It has been a busy week, so I will pass you over to Peter VK7PD to start the update.
“John Moyle Weekend
What a weekend it was too! March 19 and 20 saw at least 3 things of significance happen to VK7s: The John Moyle Memorial Field Day (JMMFD), The Meet the Voice (MTV) picnic at Ross and the Kentish Equine Endurance event.
For the JMMFD, NTARC had 2 member groups operating portable stations of which the writer is aware:
One at the ‘new site of ‘Drivers Run above Waverley on Saturday only, and the other, an all-weekend event, at the Ross Caravan Park, site of the MTV picnic.
The Drivers Run operators were Andrew VK7DW and James VK7JAM with VK7PD acting as ‘roadie. A photo of this station has been posted on the VK7 Amateur Radio Facebook page.
Andrew and James were QRV on 5 HF bands plus 7 VHF/UHF/microwave bands. HF contacts were made to interstate and ZL. VHF/UHF/microwave contacts were made to VK7ZBX and VK7ZMS on Mt Wellington and VK7MO at Tolmans Hill. Local contacts were also made on some of the above bands.
Meanwhile Peter VK7KPC was using his station at the Ross Caravan Park adjacent to Dick VK7DIK from Ulverstone. Peters lineup of gear included some ex-military equipment; he was heard making contacts on VHF/UHF to the Mt Wellington pair and HF contacts much wider afield.
In all the JMMFD participation was successful despite the small number of field stations. The weather was kind to all and the Drivers Run site appears to be worth a future visit (VK7DW had close to 80 contacts). Thanks go out to all those home stations around VK7 who participated and gave out numbers for the contest. We hope that they too will submit logs.
73,
Peter VK7PD”
Thanks Peter for the John Moyle Memorial Field Day update. I must also agree that Peter VK7KPC did indeed have a very respectable setup, operating from the back of his vehicle, encompassing modern amateur to ex-military equipment, rumor has it that he also made about a dozen CW contacts from this location.
Well done Peter, obviously the Morse Code practice nights have paid off. HiHi
The NTARC Safety Communications Team that helped at the Kentish Endurance ride also had an enjoyable time, if not an early Saturday morning start at six am on site at Sheffield. From both providing safety communications for the Equine event point of view and meeting up with the North West crew headed by David VK7DC it was a good days outing. It allowed some of us to finally put faces to call signs and have a chat. Thank you to our crew, Roger VK7ARN, Peter VK7SP, Idris VK7ZIR, Andre VK7ZAB and Stefan VK7ZSB for lending a helping hand. Even after a long Saturday over half our crew made it to Ross and along with other NTARC members once again had an enjoyable day renewing acquaintances from all over the state, a very fitting end to the weekend.
Once again it was a club Tech night this week, so over to Idris for another update.
“Tech Session Report for Wednesday 23rd March 2022
Tonight we had a plethora of displays which ignited much discussion and many covers were removed!
Ross VK7ALH arrived with a like new Yaesu FT 101EX. It was actually a New Old Stock 1970s item which still had the protective plastic film on the front panel. The FT-101EX was the Extreme Economy FT-101E type which had all FT-101E specifications without speech processor, DC converter for mobile use, microphone, DC cord, fan or 160m crystal. Ross had scoured his online sources for the available options and installed them all, except the DC converter, the result being a near fully specified working radio. An immaculate job. Thanks Ross.
Peter VK7KPC had recently acquired a British Army Larkspur wireless set B47 FM VHF transceiver, 39 to 56 MHz powered by 24 Volt. These were made by Plessey in the 1950s and used for communications between armoured fighting vehicles and infantry. Peters example was in immaculate condition and included headphones, microphone and remote gain control. We were treated to a peek under the covers revealing the amazing rugged layout in these radios. Definitely built for the battlefield. Thanks Peter.
At this point I would like to say a huge thank you to our members with amazing collections of radio equipment who bring us interesting examples for display and discussion at Tech Nights. This also goes for all our members who enjoy the Tech nights and bring along the many and varied items of interest and projects for us to enjoy. Thats what its all about, getting maximum enjoyment and learning from our great hobby.
Also on the menu was a Codan marine transceiver from Idris VK7ZIR, really only suitable for spares but an interesting example of an Australian made radio nonetheless. Quickly snapped up!
Stuart VK7FEAT had a very intriguing item which looked very much like an aircraft remote head for direction finding equipment, vintage unknown. It had a large frequency dial marked in kilocycles and controls for antenna direction and range. With a tuning meter, this item was made by Marconi and labeled Receiver Controller. There was some head scratching and inspired guesses from observers. Thanks Stuart, maybe someone will have more of a clue next time,
To round off the line-up, Lionel VK7LB had a more modern exhibit for us in the form of a computer bulk data storage drive using DDS tape cartridges. Non-operational, but the entire mechanism could be examined in all its amazing miniaturisation and precision.
Another stimulating and enjoyable evening.
73 de Idris VK7ZIR“
Thank you for the update Idris. It was indeed a very full evening and midnight approached all too rapidly!
By the time this goes to air, hopefully Bernie VK7BR will be out of hospital and recovering at home from a non Covid 19 related problem. We are all concerned and wish you a speedy recovery.
UPCOMING EVENTS
TestNet and TechNet – Wednesday 30th March. TestNet/CW course on 3.580MHz from 7pm till 7.30pm….and a TechNet on 3.567MHz from 7.30pm till about 8.30pm. Your host for the evening will again be Nic VK7WW.

North West Tasmania Amateur Radio Club
Kentish Equine Endurance Ride – out of Sheffield
Saturday 19th March - Dave VK7DC, Matt VK7ML, Ross VKWP, Ric VK7RI and Roger VK7ARN together with a contingent from NTARC – Idris VK7ZIR, André VK7ZAB and Stefan ZK7ZSB provided tracking and safety communications between four ride checkpoints and Base. Some early concerns about simplex coverage proved to be unfounded. The weather demanded a multi-layered approach for the first few coolish hours from setting up at 06:00, but a clear sky later sent all looking for shade. The riders had to put up with hot sun above and a hot horse underneath!
The day was relatively uneventful with only rider progress reports and only two calls for assistance – one for a float to pick up a horse with a thrown shoe and another for a replacement stirrup.
There were 57 entries – 32 entering the 80km ride, being two legs of the 40km track; 22 completed. 15 did 40km, 12 completing and 10 20km, 9 of who completed.

DATV Experimenter's Night
Our DATV Experimenters night broadcast started with Rex Moncur VK7MO in the studio with a wonderful description of the latest AR magazine article featuring Rexs Dad Len VK3LN and his Mum Phyl. Len was one of the first amateurs in Australia to build a TV transmitter and receiver and transmit and receive pictures via radio.
Rexs Mum wrote a column in AR magazine in the 50s called YL Corner and Rex showed a 1957 YL Corner called “The harmonic” which was written about Rex growing up through his teenage years. Great memories thanks Rex.
Rex then took us through his time as Director of the Antarctic Division when Dick Smith asked for permission and assistance for his flight to Antarctica. Rex related the delicate situation with the United States and their position on providing assistance to outsiders.
Rex then outlined his article about the VK-ZL contacts made by himself and Richard VK7ZBX and the learnings about tropospheric ducting - definitely more to come in this space, thanks Rex.
We then got Richard into the Studio and went through the AR magazine article on Richards 1.8m EME portable rig. Thanks Richard.
Richard and Justin VK7TW then went through a summary of the John Moyle Memorial Field Day operation and the Meet the Voice event at Ross.
Justin then showed the final matching network arrangement for the 30m end fed with pictures and the NanoVNA results.
Justin showed the Vacuum Capacitor he bought from Bryan VK3KWB at the Meet the Voice event and the plans he has for a 30m / 10MHz Magnetic Loop and there will be more about this in the next show.
We wrapped up with a reminder of the future events.
https://www.youtube.com/watch?v=FcnGVmKQATc
This week we will be having a quiet night in the clubrooms with the DATV night streaming coming from the quarantined shack of Justin VK7TW!
We will only be going out with a streamed show from the REAST YouTube channel.

Australian document on VDSL2 interference problem
Australia's National Broadband Network (NBN) has produced a document that suggests radio amateurs cause interference to VDSL2 - reality is it's VDSL2 and the RF pollution it can produce that is the problem!
The introduction says:
“This document is intended for technically-minded users or those providing technical support to users connected to the nbn network who are experiencing signal interference between their nbn service and amateur radio transmissions. It is assumed that the people referencing this document will have a reasonable understanding of electronics, wireless transmission and broadband transmission technology including digital subscriber line (DSL) and very high-speed DSL (VDSL). With that in mind, this document would be suitable for licensed cablers, telecommunications network technicians, operational support staff, network engineers and amateur radio operators.”
