Date23/05/2024 “Have a Read” Roger Harrison has advised about the latest AR Magazine featuring “Lighting Scatter” See more Here:


Date 6/05/2024 “Were off To Bundy” Some of us travelled to Bundaberg Qld, for the WIA Convention. We went to promote our Club and wares. It can be reported we did all three and more. Several enquires about our Club, also we chatted with the Icom representatives about the IC9700 and the new kid on the hills IC905. What a weekend all about radio and meeting all thought faceless contacts. 









28/04/ 2024. “M A D went ATV”  Sunday we held our M A D(Microwave Activity Day) with many of the hills activated between Melaney,Toowoomba and Deep South in VK2 (VK2SRC). Some operators equipped with the new IC905 were testing these useful rigs with VK2APV (Peter) and VK4MJF (John)making a contact on one of the modes available on the IC905 being ATV. Rain was a forecast, well go figure they got it right, and limiting some contacts. 


25/04/2024 “Star Nite” Roy (VK4ZQ) gave us talk on satellite operation last evening, highlighting the history, insights and the gear required. Very nice presentation and our thanks to Roy for the effort, all or guest speakers are available on our Utube channel, caught up with Roy and many other. 


6/04/2024 ” RedFeast Talk”  VK4CZ has reported on VK2ZRH/4(Rodger) Giving a very interesting talk on Micrwave/ Microwave Activites in the conference room @ REDFEAST 2024. Also a demonstration was conducted on the IC905 showing its Microwave ease of working, including the ATV(amateur TV) usage, with many of us rather chuffed, on its ability.








20/03/2024 ” Meeting Reminder” 27th this month. Theme for the meeting will be Show and Tell  If you have an interesting project or ideal bring them along please.


6/03/2024 “Buyers Remorse “ A post found a user Group, “It is unfortunate that so many design flaws exist in the 9700. I had a girlfriend once that was pretty but high maintenance. The 9700 brings back those memories. So, after dealing with instabilities, design that requires more cooling, and being unable to TX with my handheld while installing antennas without requiring repairs, I bid my 9700 a fond but final farewell at the last hamfest. I will miss her once in a while, but not the patchwork of requirements for operation. And the 9700 too.To answer the obvious question: A Q5 5BVUX and my TS2KX for IF. Leo bogners  I may replace the Kenwood with a 7300 or K4 if I miss her too much

6/03/2024 “Stability Question” > While Leo Bodnar claim their GPSDO is low jitter, my measurements show mine has relatively poor short term stability compared to my home made
GPSDO. This short term stability equates to approximately +/-0.5 Hz at  23 cm (4 parts in 10^10). There is a plot of the 10 MHz output at:

That makes sense of course since the short term stability of a GPSDO is
achieved with the OCXO, which the Bodnar unit doesn’t have.

!/03/2024 “24GHz Tri Out “ We would like to invite any interested parties to join us on the air for a radio test today 1st March 2024 Friday TX time approx 1600.

VK4FB(Rowland) and VK4CSD(Stephan) will primary attempt  a QSO on 24Ghz from Kamerun Lookout to Maleny McCarthy lookout.
Despite the expected high humidity we do hope to receive a weak signal.
Our intended talkback will be on 5760.1Mhz FM.
If there are any request/interest for any other frequencies we might be able to add some extra bands.
Obviously we would need to know prior departure.

28/02/2024 “10GHz Record Falls” Brisbane VHF Group was awarded VK4 State 10GHz Digital Distance Record. 

Congratulations to the Brisbane VHF Group members with Kevin VK4UH and Col VK4UV at the “other end” of the contact.

14/12/2023 “Beacon Report Update” VK4RBB – BACK ON AIR

Hi all
Our main 432MHz-47GHz beacon VK4RBB at Edens Landing is back on air
It has been MIA for several days following the failure of the 3398.440 output on 9cms band
Thanks primarily to the efforts of Doug VK4OE the faulty PLL was replaced and the system reinstalled today
Reception reports are welcomed for the outputs on all bands
(NB. The beacon antennas are not at full height at this time)
Please post reports and comments here
Seasons Greetings to all
(Kevin VK4UH)


 12/12/2023″Licence Changes” ACMA and the WIA have new ideas on our band plan and the ACMA goes ahead with Class licensing See Here: 

 12/12/2023″POMS GO MAD” Ofcom in England have made big changes to there band plans and operating conditions See Here:



6/12/2023 “Beacon Report”  Doug (VK4OE) reports VK4RBB beacons are off line for further updates. Doug had found it nessicary to utilise this period to fix the issue with the ZLpLL , hopefully the fix will be done before the holiday season.

11/11/2023 “Beacon Report” VK4CZ in QG62LP08 has reported Our Club beacons as:

Firstly, thanks for the effort – it’s truly appreciated.

I’ve just completed a check [first chance I’ve had] and the beacons 70cm through 9cm all heard from home station, but down on what I typically see.

  • 432.440 S7, typically S9++
  • 1296.440 S5, typically S9
  • 2403.440 S3, typically S7
  • 3398.440 S1, typically S2-3

Will recheck tomorrow morning when next in shack, to see if just local condx.

Happy hunting to all out there.


7/11/2023″ Our Beacon are updated “ VK4RBB is in service again after an update, thanks to all that assisted.

4/11/2023 “VK4EA Reports on Our Beacon”. VK4RTT 50.285 & 144.440 MHz on air running barefoot beaming South from QG62mo. Alternates between FSK and PI4 modes. Reports here and/or vkspotter appreciated.

16/08/2023 “Icom goes 24GHz”  Icom are about to release a 24GHz system which maybe  integrated with the recently released IC905,  See Here:









23/7/2023 “IC905 tests OK” VK4MJF(John) has reported on the IC905 being a very easy radio to run microwave bands, testing on Sundays 23 on 23/ Microwave Activity Day (M A D). With its 2 watts on 13cm and 6cm contacts were made from sea level to about 900 metres 120Kms with Colin VK4UV giving 5/7 report. With a bit more practice on peaking the external gridpaks some further distant contact would be possible, keep tuned. John also reports the radio was operated by his local Club on the UHF/VHF Winter Field day @ 1000 metres out near Warwick Queensland with the same ease to setup and operate. One of the local hams has purchased the IC905 to 3cm, John has reported some ATV and further testing/ tuning will be assistance to both stations.




23/7/2023 “PILEUP 23cm Yes on SHF”  Today’s M.A.D./ 23 on 23 has been a great success with about a dozen or so operators  on the bands used, in VK4 and VK2. All bands from 23cm-3cm were worked with the yellow jersey being shared with a 3cm SSB contact with VK4CZ/p(QG64HA) /VK4UH/P(QG61NU) 249.2Kms  and the team of VK4AFL/VK4FLR for their 3.4GHz contact on Q65 528Kms. It seems some hill top location was the place to be, with most local contacts on 23cm, the VK Spotter looked like a rainbow with the amount of contact band  colours displayed . Here most of the todays winners VK4 KLC-CZ-HF-UH-CRO-CPS-MJF-SU-VU-UV-HF-RF-KWS-AFL-FLR-EK,AK for being there. It was nice to see some new faces also testing their equipment, there was an incomplete contact on 3.4GHz between VK4UH and VK4FLR good going, Frank (VK4FLR) reported some more work to be done. See you all on the next one.  



20/7/2023″MJF TV” VK4MJF reported the IC905 will work out of the box on ATV. So far the rig has been a success in the shack and Field day(Winter). Looking forward to the 23 on 23 this Sunday for a workout.








17/7/2023 “M A D” Its 23 on 23 this Sunday 23rd. There are hills looking for the new gear test,  here you there. Click here:

Maybe its a recommended suggested retail price, Dealers price maybe($4200) will not brake the bank as much, Khune gear is looking low price at this stage. 

20/03/2023″Few out for the John Moyle FD” John Moyle Field day was a great chance to try all the mods and new gear on the week end. Although the weather was fine and clear, the heat was a telling factor which may have kept some station at home in the air-conditioning. Several Club stations braved the conditions out on location, VK4WIE, BAR and VK2SRC were some. With VK4UH, AFL,EA,UV,CZ,OE,DCM trying out 1296cm and up.



A few views of Mt Cootha







1/3/2023″ Results Confirmed” VK4AFL(Trevor) and VK4FLR (Frank) confirmed 3.4GHz QSO this morning 28/02/2023. After completing with Q65 , they followed on SSB. With excellent tropospheric conditions, SSB signals on 3.4 GHz were 5/9 plus. 

After months of watching early morning conditions on the Rockhampton to Brisbane path, both were overjoyed with the morning results. Frank headed off for a celibately breakfast. 

Their efforts were witnessed by VK4MJF, receiving both modes of Q65, +7 and SSB 5/5 +. John then celebrated with a SSB contact with Frank on 23 cm SSB.


70cm IF (3398.215MHz)


28/02/2023 “3.4GHz prize missed” In the small hours of the morning, some Hams like to try their luck at sometimes impossible contacts.

VK4AFL(Trevor) and VK4FLR(Frank) each morning brave the sandman and make what has been very successful over the last 12 months of so, contacts on 2m/23cm with Q65 digital mode, most morning around 6:30am(7:30am that other time). They reported, “as todays contacts on each band had something special, they tried their first contact on 3.4GHz”. VK4UH assisted by VK4UV and VK4AFL(Brisbane) had successfully achieved from VK4FLR ‘s deck in Emu Park, near Rockhampton about 524 Km on the 28/05/2022, claiming the distance record for that 3.4GHz band.both report:

Transcript Report  notes on first RX decodes results re propagation tests on 3,398.215 MHz   at 524km VK4AFL to VK4FLR 

Logging comments/discussions by  VK4AFL  & VK4FLR   28/2/2023 

Subject: 2m/23cm/9cm.


Trevor “Hello Frank “– Below is a prize decode & all we need now is to finish the job!  With power, pointing & other variables not previously confirmed today was very encouraging as it proved a few things not the least being it’s a goer.  As you said 23 cm conditions & when they peaked coincided with 9 cm decodes & whilst 23 cm was better than it’s been they were nowhere near what we have had e.g.  S9+.  We will never know for sure how far short we were but my guess is not all that much! 73, Trevor.


Frank”Yes Trevor”  –  The key to these  results is without doubt your 1.8 m dish which as sun noise results confirmed a few months ago is working extremely well. I cannot detect any sun noise with my  [Kevins] 1.1 m dish. I did later wonder given the time spread of the decodes if 30 second sequences would be any advantage?  Given that all previous Q65 contacts were 15  seconds perhaps stick with that?  Tnx for being there & hopefully we won`t have to wait too much longer but we might which is not a problem.

Further updated details will be posted here soon :



9/02/2023″ Club Beacons up for test” Doug VK4OE has posted.” As a kind of “soak test”, I have set up the ZLPLL and beacon controller parts of our VK4RTT beacon, transmitting at quite low power levels into external antennas.  There’s 4 mW output on 50.285 MHz, and about 12 mW on 144.440 MHz, both with vertically polarised antennas.  Location is Annerley, QG62ML.

I propose to leave this running for a week or more to see if anything untoward develops.

Reports of signal reception and clarity, noise pedestal (if you can hear that…) and anything else you can discern will be welcomed by replies to this group, or direct to Kevin (VK4UH)or myself”.

26/01/2023 “Aussie Record” It might be Australia Day,and some of us are out to lite the barrby etc, but our hobby moves on. This morning VK(AX)4UV and MJF made a landmark digital contact on 2.4GHz which we believe has been listed in the WIA records, over this distance of 63.6Klm’s. Great going boy’s look forward for the next ones. Certificate is in the mail.





17/02/2023″VHF/UHF Field day” Although we are all awaiting the last 2 Field day results with some lame excuse for why the results are not done. We found lots of competitors out some where for this years Summer field day. Many were seen (Heard) up and down the east coast great to see so many enjoying the event. Many operators were using single letter contest call signs such as (VK4I/S/Q) and a call that hasn’t t been around for some time VK4WID Toowoomba, great to see them along for the ride.

11/02/2023″SHF God” We would advise Trevor VK4AFL fell and broke his femur and hip. There was an operation and he has a blood clot in his lung. Not as reported earlier. This publication wishes to apologise for the incorrect reporting and hope for Trevors recovers quickly and returns to our Hobby very soon.





28/11/2022 “IF Melted Bunya Mt’s” Our Club call sign VK4IF was heard over the country side on the weekend from their retreat on Mt Mowbullan (Bunya Mt.) Thanks to VK4 EA (Peter)UH(Kevin) CZ(Scott) UV(Colin) nice work. See Here:

“Mt Mowbullan is at a “good distance” from Brisbane so contacts, especially on the higher bands, are challenging and a very worthwhile tests for everyone’s VHF and microwave equipment”.” UH wrote. “( CBRS has reported VK4IF with 5/9+20 as a report on most microwave banks up to 10GHz from QG62JW Mt Mee)”

26/11/2022″Kevin (VK4UH reports”)Although there is no formal club meeting in December we will again be arranging an informal lunchtime BBQ gathering on Sunday 11th December – at a suitable venue to be announced – for members and partners to meet up before the holiday.

25/11/2022 “Spring Field day” Some of us are out and about north of Brisbane 8and 24Hr see you all on the day.

24/11/2022 “Shocking Information” VK4UH(Kevin) has given a talk on shack accidents and the treatment if this mishap is confronted. See here: Dr Kevin(VK4UH) travelled with many others down to Hobart for there Reast Hamfeast in the University of Tasmania grounds , were he was asked to present a very important subject which seems to be glossed over in many and all shacks.

22/11/2022 “Big Nite Wednesday” First Our Club November Meeting on the 23rd @ Chermside library last for the year, plus 23 on 23. So take your pick or do both. Zoom in to the our club meeting and 23 on 23 as well. Like the heading states (Big Nite Wednesday.)

2/11/2022″ More Power to the people” Roger Harrison had mentioned in our October Club Meeting about the WIA getting involved with the ACMA on new power and band plan changes, ACMA proposals on Class Licensing 

1/11/2022 “All Beacons Out” Doug VK4OE reports.

Greetings to all! I have just returned home having been at the ‘RBB beacon site this morning to begin trouble shooting, as well as enjoying catching up with Rob!

I have had to shut down the whole ‘shooting match’ because the fault with the 3398 MHz beacon has been traced to the main PLL and signal generation module which is common to all of this beacon’s outputs.  Previous faults with the 3398 MHz beacon have been in the power amplification module separate to the ‘main’ module. However, this time Rob and I were able, by using Rob’s microwave signal generator, to verify that the 3398 MHz power amplifier is still in good working order. I will find out what has happened in the 3398 MHz generation department and attempt to fix it as soon as possible.

Whilst on-site today, in relation to the apparently-failed 24 GHz output, I was able to verify that the signals leaving the main frequency generation module headed for the mast-head unit where the 24 GHz output is produced, were all present and at their ‘normal’ power levels.  The fact that the 10.3 GHz output (also amplified in the mast-head unit) is working narrows down the areas where the 24 GHz fault may have happened. I will further report on the overall ‘RBB situation when there is significant information to report.

Thanks for your understanding!

1/11/2022″Beacon Report” VK4UH(Kevin) has reported on the Club beacons (VK4RBB )@Edans Landing (near Beenleigh Qld.) .

Currently 432, 1.2, 2.4, 10 GHz all received on 30/11 at expected signal levels. Following some reports of 3398.440 MHz (9cms output) being not detected, also nothing detected.  5760.440 MHz (6cm) at this time not checked. We await the update results on the undetected pair.

23/05/2022″ MEETING THIS WEEK” Don’t forget the Wednesday 25th AGM. Big nite.

10/05/2022″2/6M Beacons ” As an ongoing update to our Clubs beacons, the 2/6 metre beacons have been installed at their new location, as reported a few weeks ago. Both were under test and performing well. As a precaution they have been taken out of service owing to a few minor changes in configuration as observed will being under test. It is hoped that this will see them back in service very soon.

30/04/2022″BeamMeUpScotty” VK4CZ(Scott) has held a show and tell day at the Kingston Park demonstrating 3.4GHz and Microwave in general. He reported 20 odd from all walks in life in the district had turned up for the event with VK4 CSD, VU and ALF helping out on the receive end. More here:

24/04/2022″May M.A.D date Change” As the May M.A.D day was to be held on the 22nd May 2022, it has been rescheduled to May 29th 2022.

VK4UH has report his intention to have a 2 man team with himself and VK4UV will undertake a Microwave road-trip to Mt Archer near Rockhampton to coincide with the May 29 MAD.  

U-wave tests back to Brisbane and the South will be run over several days around the weekend of 27-29 May on bands from 1296 to 10GHz looking for Tropo or Aircraft Enhanced propagation.

we hope as many club members as possible will activate and support these tests



21/04/2022″23 on 23” Saturday 23rd April is not Aprilfools day but some of us try, 23 on 23 someone could be on try it out 7.30-8.00pm, 1296.100MHz(23cm).

18/04/2022″ Club 2metre Beacon” Peter (VK4EA) reports the Club 2 metre beacon is back service. Great stuff.

22/03/2022 “OE on Antenna’s” At our March Club meeting Doug(VK4OE) gave a very interesting presentation on antenna building or repair. For those contemplating such projects a quick glance at this UTube presentation may find it helpful. See here.

15/03/2022″THE M A D is on”Our Club is holding the next M A D on the Sunday 20th March after the John Moyle Contest.

14/03/2022″Club 2m Beacon is up” Peter VK4EA and Kevin VK4UH returned the beacons to its permanent location on Mt Coot-Tha after its long holiday, with the 2m section is now operational on-air. Sadly we identified an issue with the 6m X-dipole where the SWR was found to be raised just enough to cross the Hi-VSWR threshold of the protection circuits and tripping that transmitter intermittently.  It is possible the recent rain events in Brisbane have waterlogged the antenna. We will be returning soon to completely revise the antenna system and return the 6m beacon to operational.




Beacon new home.


24/02/2022″ Club GPSDO – OCXO – 10MHz” Last nites meeting went well, with lots of M A D Stories from the weekend past, highlighted by VK4AMG’s (George)presentation on the Clubs GPSDO – OCXO – 10MHz reference project. Which will feature here in the next few weeks

20/02/2022″MAD was great” lots of us all over the Queensland area, many contacts were on offer and I’m sure there were the odd failure due to some reason or another, odd that, but thats what a MAD is! Several operators have mentioned their adventures in the positive and are eager to take part in future M A D ‘s.


17/02/2022″ITS ON” BVHFG Meeting Wednesday 23 Feb 2022 Kevin(VK4UH) reports.

Yes the meeting IS ON at the Chermside Library and via ZOOM next week 

(After the recent changes in Q-Gov policy from Feb 7 we are now able to reopen.  Its unclear if the library is one of the venues where we still have to check in or not – but this is no big deal)

The meeting will include a presentation by George VK4AMG on the Club reference project that we have been working on.  

George will be showing prototypes of the various proposed modules which will be produced for sale.  He is donating all profit from sales to the group.

As well as employing ZOOM for members who cannot attend in person we are going to record the presentation for “wider distribution” outside our own membership, to promote the project.


14/02/2022 “WE’RE GOING MAD” Sunday 20th February 2022 is the next slotted M.A.D (Microwave Activity Day.) There has been a lot of interest in the day, with most operators offering there preferred sites(Nth Qld to Nth NSW, being some.) Suggested Bands 1296cm to 47GHz and UP?. Starting 10am till 3.00pm, using a contact Frq .100 each band for all contacting, to QSY to .150/ .200 for further communication. Also a network repeater system has been suggested for further contact verification etc, LISTED HERE: and please remember lots of us have to set up in selected locations so be patent have a coffee, 10am maybe a little early for some.

For the last few MADs we’ve enjoyed the benefits of the SE Qld Wide Area Network for liaison, and the WAN has just been made even better!




8/02/2022 “Club Shop” As 2022 has a feeling of change we have decided to include a shop Menu for some interesting Club retailing ideas. Please feel free to use the shop as all monies generated go directly to the Our Club.

12/01/2022″MEETINGS OFF” VK4UH(Kevin) has posted this important Notice, please read.

As previously posted the first group meeting for he New Year was scheduled for Wednesday Jan 26 at Chermside Library (Thats next week as this is being posted).  The Library room bookings are made for the whole year and well in advance for our meetings.

The Jan meeting date of course turned out to be on Australia Day and so the decision was made to hold over the planned presentation until the Feb meeting as we expected turnout to be low because of the clash

A lot has happened in the last week of course.  With over 20,000 new Covid cases in Queensland yesterday alone the predicted peak infection rate is proving to be a reality.  

Understandably many people are avoiding any unnecessary group contacts at present and other radio clubs have already closed their doors for face to face meetings at this time.

For January we have decided to CANCEL the Library meeting when numbers would have been low anyway 

We have the option to run the planned January meeting on ZOOM only or can postpone altogether till February


When you read this could you post a reply here to indicate if you would join in a ZOOM meeting next week.  
If there are no positive replies then we will cancel until February.


6/01/2022″Meeting changes” Kevin (VK4UH) has announced a few important changes for the January 2022 Club Meeting. We had planned a presentation by George VK4AMG on that evening to provide the technical background and an update of progress on the clubs 10MHz GPSDO / OCXO /distribution module project. As January is a very important social event, Georges presentation will now moved to the February Meeting. With a lesser formal meeting in January either at the Chermside Library or on ZOOM.

1/01/2022″ A New Year” Covid seems to be the driving force for the world today, keeping lots of our Club activities/field days to be put on hold.

First out of the blocks for 2022 is in January, John Hull Memorial VHF/UHF Contest, starting on 1st January.

Quickly followed with the Summer VHF/UHF field day on the 15/16th January 2022

And we quote: “Soon as I got home from the meeting tonight I swept one of the 360 deg. slot antennas,…… not sure if I beat Doug though. 

 Return loss at 2400.0 Mhz was about 11.5db, best up the band further for WiFi of course.

Not defeated I thought there must be a way of improving the figure.  Found the sweet spot in the bottom section just above the probe and is now better than 20db match, using just a couple of magnets!!  Looks promising”

VK4AFL with VK4FLR have been making contact on 2metres and 23cm Q65(with the SSB contact as conditions allow.) As the family is growing both ends, it maybe a worth while look. Nice screen shot of one contact.


See here for more information


6/08/2021 “IC705 Review” Icom IC705 has been available for a good six months and a test report maybe of some interest. 

As the IC705 has frequency coverage from 160MHz to 432 MHz many transmission modes, with the inclusion of some newer data modes, including DV(DStar). Being easier to interface with your PC. Most features were adopted from Icom’s first SDR, the IC9700 with the addition of HF added makes this radio a true winner for the purchaser.

As there is little out there to compete with its versatility and Architecture(IC9100 offering HF/ 1296cm maybe), the IC705 offers small but vital pluses. Being around the screen is quite amazing, with a large easy to read colourful touch screen and very few knobs, it just seems to operate with ease.

Low power on portable operation(5watts on board battery) or connect a 12volt supply giving(10) watts, also adjustable per band power (great for running transverters). It is believed the IC705 will replace the favoured FT817/818, for portable operation. 

As a field day radio/SOTA the IC705 just seems to make most challengers a breeze. Transverter operation is made easy, its on board calling function, easy read touch screen and the list just goes on. 

Some failing of many passed radios has been addressed, also in the new IC9700 was on drift on digital modes (such as whisper,JT65, FT8 etc.), this has been tested with great success with on board bands also as an IF radio on 1296cm and higher frequencies with great reports, and no reason to add further modification. 

So with a price point being validated to much higher than other radio’s used in this category , they just don’t compare.

12/07/2021 “M A D ” Activity day.

Brisbane VHF Group

From the President’s keyboard………….

Good morning everyone

The next Microwave Activity Day (MAD) falls on   Sunday 18th July – which is this coming weekend as this is being written.

Several operators have already committed to going to portable sites, based on comments posted on the groups Facebook page.

Scott VK4CZ/p

Greens Hill Boonah         QG61IW               (new site for most of us I think)

1.2, 2.4, 3.4, 10GHz

Robert VK4CLG/p

Howell’s Knob                   QG63JF

1.2, 2.4, 3.4, 5.7, 10GHz

Kevin VK4UH/p                 

Mt Mowbullan (Bunya) QG53TC

2.4, 3.4, 5.7, 10GHz   (also 24GHz if any takers)

11:00 am local time for start of activity.  (Allowing for considerable distances being driven by some operators and to allow for best conditions that day)

Weather forecast is currently fairly good for the weekend, 

zero – very low chance of any rain, temps up to 22C, Relative Humidity below 40% in the early afternoon, medium wind only

Who else is likely to be active, either from home stations or from portable locations?  

Please post your intentions (and in particular the gridsquare of your station if you know it) on either the Facebook page where everyone will see it or e-mail me and I will add it to the list.

Warm that gear up and make it work for its living!

Remember also that this is the perfect opportunity to invite other operators to come with you and get some exposure to microwave operating.


The next formal meeting of the group is also approaching

Wednesday 28th July at Chermside Library and relayed on ZOOM

The intention that evening is to have :-

Round Table Discussion on “LIAISION” during MADs and Contests

Defn.   “communication or cooperation which facilitates a close working relationship between people or organizations.”

In the hope we can all be aware of all the methods available to us for arranging and coordinating microwave contacts and getting the best “bang for our buck”

Please come along and put your point of view

Regards and 73

28/06/2021 ” Lots of Activity over the Land” This years, Winter Field Day seem to hold a bit of interest over the Week end. Great to see calls all over the country, VK4-VK6 all had a great time. VK4UH (Kevin) reported on his trip to Ocean veiw posted this : see here

20/06/2021″Message from the new Boss” Greetings to everyone

The next meeting of the BVHFG will be held:-

                                Wednesday 23rd June (from 19:00)

                                Chermside Library

                                375 Hamilton Rd, Chermside 4032

                                Entry via main door on Hamilton Rd (Call Pres on 0407 799664 for access as this door is closed out of hours)

As my first duty as the new group president I would like to express my thanks to the membership for allowing me the chance and honour to take up the reins of the group for the forthcoming year.

On everyone’s behalf I would also like to pass on an enormous vote of thanks to the outgoing president Doug Friend VK4OE who has been the voice and guide of BVFHG since its earliest days.  Very big shoes indeed to try to fill.

I intend to use both e-mail and the BVHFG FaceBook page to disseminate notices and information about club meetings and activities around the group.  I hope to be able to offer advanced notice of topics to be discussed and presented at forthcoming meetings

For the meeting this coming week I plan to give a short presentation on QRA-64

This is a new digital mode freely available in the latest versions of the free software platforms WSJTx and MSHV.   This new mode has great potential for many different modes of operation on both VHF and microwave frequencies for a variety of different modes of propagation including Tropospheric Ducting, Sporadic E, Ionoscatter and Aircraft Enhancement.  It is currently the “best of the bunch” and is in regular use by several local stations for long distance Aircraft Enhanced contacts on 23cms and has proved very effective on microwave bands right up to 24GHz for weak and obstructed paths.  It has also proved to be effective for ionoscatter (D-Layer) propagation on 6m when no other mode of propagation is present for example between Brisbane and Adelaide on 50MHz.

For the following meeting in July 28th I propose to organise a “Round Table” meeting to discuss “LIASION for Microwave and Portable Activities)

It is hoped that as many people as possible might attend this meeting to openly discuss all the possible options for Liaison and communication while out on hilltops etc

This is something that as a group we have been very bad at in the past.  Many possible contacts have been lost since we do not always know with any certainty who and where people are operating

Please come and put your ideas and suggestions forwards for everyone to discuss

You never know we might even be able to agree on a way forwards!

The winter VHF Field Day Contest falls next weekend as this is being typed (26/27 June 2021)

There are already plans in place by a number of members for portable and home based activities for that contest.

I suggest that everyone intending to operate makes their plans visible on the club Facebook page, indicating location, bands proposed and likely activity times for other members  to see

As always plenty of time will be available for “show and tell” of any underway projects and everyone is encourage to bring things along to be seen and discussed.

We look forwards to seeing as many members as possible on Wednsday as the start to a new and exciting year

Regards to all

Greetings, gentlemen!

In recent times, following some improvement of my injured hand, I have started to drive my van again.  So, this morning I have gone up to Panorama Place (in the suburb of Mt Gravatt) to listen for VK4RBB on all of its output frequencies.  It is a full-on line-of-sight path between the two sites, and it is a stupendously beautiful day today!

My report is that all output frequencies were received at good strength, 432 MHz right up to 24048 MHz, and that the ‘CW note’ was pure on all transmissions.  Of course, this is a report from today only and it is not possible to project this report back onto previous occasions.

So if anyone monitoring any of the ‘RBB outputs notices a rough tone or a noticeable reduction in signal strength where you are, please get back to me by e-mail or ‘phone (0428 191066).

Cheers and thanks in anticipation,

–Doug, ‘4OE.

Preferred digital mode on microwave bands will be QRA64 – but anything will be possible 

Liaison for contacts

The plan is to have a presence on VKSpotter and Contest Radar websites during the contest.  

We also hope to be monitoring the Brisbane VK4RBN repeater 147.000MHz as the actual Bunya Mts repeater is currently off-air

Both Col VK4MIL and I will be contactable via Mobile Phone TEXT at any time (4UH 0407 799664,  4MIL 0421 250447) to coordinate contacts

Your Group Needs YOU!

As always we will be at a significant disadvantage in VK4 due to our geography and our low amateur station density in VHF range of us when compared to contest stations in the southern call areas and states.

We make a special request for members to come up on-air, on whatever bands you have available, to work VK4IF/p during the contest. Home portable or whatever.  We just need a report, serial number and your gridsquare if you know it.

We can make contact repeatedly every two hours on every band and get full points each time 

Hope to see you in the Contest

Don’t forget we have a ZOOM BVHFG meeting this coming Wednesday evening (THIS WEEK) and can discuss this further


Date 15/11/2020 ” Spring Field Day” Plenty of activity has been noticed as we move closer to this Event.

Date 17/07/2020″Looking for Young Operators ” Interesting read.

Date 29/06/2020 “M A D EVENT iN JULY” Some keen Contesters are feeling the gap between the Winter and Summer Field days a little long time to wait. So a MAD in July has been muted (26th after the 23 on 23) seems great idea.

Date 24/05/2020 “M A D EVENT” All had a great day either at home or in the field. 1296MHz – 10GHz were heard, lots of gear failure and rare DX, great too see everyone out and about in these trying times. Our next Event will be the VHF/UHF Winter field day in June.

Date 19/05/2020″Events reminder” Club Meeting Wednesday 27th all have been notified of the venue (ON ZOOM). 24 th M A D event in conjunction with 23 on 23 except its the 24th, try out you old or new gear from a mountain near you,(we are allowed out).

Date 24/04/2020 “23 on 23” Covid 19 has had an affect on lots of things, but 23cm; has to be the oddest.

Approximately 12 Hams made it to the 8.00pm session, VK4CZ<AMG<AL<GU>LHD>NA>EA>DDG>MJF>ADM>MIL>KAY as too VK2MAX. 

Not a bad role up for 23cm event, most of the signals were extreme, 59+ for most. Maybe the meteorological event or just a nite for it; lots of fun was had by all.

23/04/2020 “Z00M Save the meeting” Our Club, like many others have reverted to the ZOOM system to conduct there monthly meetings, during this lockdown event. Great meeting very well attended and some really interesting topics, all from the comfort of home.

This is a Club community announcement, Thanks for your response.

24/02/2020 “M A D Report” About 10 plus call signs were heard, North, South,West and a bit East, hills and home based. As we were all spread so far the weather caught some and not others. Some had shelter, it was great to see and hear the microwave bands rocking most of the day. Full, Standard and F calls were out trying their best to make the day. Lots of gear failure, but thats what its about 23 on 23 M A D, don’t miss the next one. 


Col made good with the portable shelter.

22/02/2020″A Visual Map” VK4CZ has posted a map of those suggested sites for the M A D. As per the list on the post dated 16/02/2020 below.

18/02/2020 “A M A D Entry” Stephen will be packing some higher bands.

VK4CSD will be active from Panorama place Mt Gravatt working Doug OE on 24, 47 and 76GHz. Due to high humidty 76Ghz will be bit of a challange. Never less, lets try it. Afterwards I can relocate if anyone wants to have a QSO I can relocate to  MtGravatt Lookout and work stations north, east, and west. on 2.4 3.4 5.7 24 47 76GHz. I might also have 10Ghz mixer level only. 

16/02/2020 “M A D is on the move” As we will be holding the Microwave Activity Day (MAD) 

the 23rd of this month in conjunction with 23 on 23, many operators are jockeying for the best hilltop location. How about you?.

Bands available: 2M/70/23cm/2.4/5.8/3.4/10/24/76/122 GHz, modes SSB, or as per liaison.

Times: 10:00am to Stumps was a starting point, some operators are going to travel longer distances, so some patients would help with there ability to be on air. Some are running 3-4 bands, others are running 8 plus, so it will be a big day.

A list so far VK4 UH/p() MIL/p(MtWoolvi) OE/p(Kamaru l/out) NE(Home) MJF(Home) CZ/p(GusBuetell) CDI/p(GormansGap) EA/p(Gantry D’Agular StateForest) KAY(Home) AFL(Home) ADC(Home)

Also a list will be published on VK Logger.

22/01/2020 “January Meeting a Blast” Many subjects were discussed Beacon repair, which has mystified thoughs charged with the repair.

Club call sign (VK4IF), has been active for the VHF/UHF Spring and Summer field days with outstanding results. 

‘Stephen(VK4CSD) gave an update on 24/76/122/245 GHz and higher bands, with a simple easy method of building these bands for fun or competition. 

MAD( Microwave Activity Day) will have the support of many club members heading to a hill near them, in conjunction with the 23 on 23 in February 2020, with all microwave bands to be activated. 

12/01/2020 “February MAD Event is coming” VK4CZ has asked for a MAD be held as per this paste.”
