Miena Hamfest is Back!

Its been a long time between drinks but after four years the Miena Hamfest returns in 2022 and at this stage it will be on Saturday 19th November. Please note we have bought the day forward one weekend to miss the VHF and Above Spring Field Day and may be bringing it forward another week so we can get vendors down to the VK7. Watch this space! 

Held at the very well appointed (and heated) Great Lake Community Hall at Miena in the central highlands of Tasmania.

We have all amateur radio clubs in VK7 involved in the organising group to promote this as the pre-eminent biennial VK7 Hamfest. 

Do you have an idea to make the Hamfest an even better event? Would you like to see something in particular at the Hamfest - let us know at

We are talking with many suppliers to try and get them down and bring lots of goodies! There will also be pre-loved tables available.

BBQ lunch will also be available for purchase and a raffle with some very nice prizes will also be on offer.

Mark it in your diary and make it a day out in the highlands.

More details as they come to hand.

Northern Tasmanian Amateur Radio Club Incorporated

We begin this week by wishing all the mothers among our listeners and all our mother members a Happy Mothers Day. As this is written on Friday, hopefully by Sunday the harsh weather in the south of the state has eased off or preferably stopped and there has been minimal damage caused by the storms. 

Now a quick round up of the previous weeks happenings. The Technical Night at the club rooms on Wednesday evening saw nearly twenty people braving the cold weather. For a brief rundown it is over to Idris.

“Our Wednesday night Session contained a veritable banquet of technical items for those braving the cold to feast their eyes on. The advance guard Peter VK7KPC had arrived and, once he had done his Duty by lighting the fire and turning the urns on, had settled himself in the radio shack to participate in the co-occurring Test Net and Tech Net being hosted by Nic VK7WW. To do this, he had brought along a modified Codan Type 6801 Mk 2 SSB transceiver. Peter had built up an American DDS kit as a VFO with a LCD frequency display, and injected the output in place of one of the Codans crystals to enable that selector position to be tuned over a range. A very neat unit and with the cover removed, revealed a unique feature, namely a three quarter inch Whitworth steel nut attached to the oscillator crystal as a thermal mass to provide some temperature stability. Not only that, but the front panel boasted a 3D printed tuning knob with a finger turner. Well done Peter.

Colin VK7ZCF had scored well in an online auction, and showed us a very nice Panduit model LS3E cable label hand held printer in a nice case with accessories and extra labels. 

Idris VK7ZIR brought in a SDR module with a frequency range of 0.1 to 2,000MHz. Connected to a computer running the manufacturers software via USB, many actions are available. The software is excellent and most importantly its free. Idris also demonstrated the latest Windows incarnation, Windows eleven, which for most aspects is a real improvement over Windows 10, particularly the User Interface.

Next is Ross VK7ALH with his usual interesting selection. Another of his Dentron Linear amplifiers, which he has left at the Club-rooms for anyone to inspect. For those who like the Eddystone marque, here was a short wave radio model EC10, in beautiful condition, powered by D size batteries in a rear compartment. The type of radio which would not look out of place on a mantelpiece in a living room. Ross intends to install a mains power supply in the battery compartment. We will no doubt see the result at a later date. He had just acquired a home-brew antenna matcher from a recent sale, which was very well built with what looked like military grade components including a very nice roller inductor.  Thanks Ross.

Our new power distribution and monitoring unit was on display before being installed on Mt. Arthur Repeater site to enable disconnection of power remotely to anything misbehaving and keeping an eye on current and voltage levels via the network from anywhere.

Stuart VK7FEAT had some interesting high current DC circuit breakers for his vehicle which were IP67 rated. He also showed a crystal oven he had found in one of his many boxes, made by GEC with an octal base, powered by 6 or 12 volts. Thanks also for splitting firewood for us, Stuart.

Before winding up, thanks must go to Jill, sister of David VK7YY, who supplied the most delicious sandwiches, as she has done on many occasions, and to Bernie VK7BR who is back on deck after convalescence and brought his delectable sandwiches too. So no one went home hungry and had to prepare a plate of food. All were satisfied in every way from an enjoyable evening.

73, Idris VK7ZIR”

Thank you Idris, it was excellent to see such a cross section of equipment brought along. Not every item being a transmitter, receiver or antenna, but never the less all parts that when combined make for a working and usable communications installation and station. Even Collins humble Panduit label maker, the once “Industry gold standard” in cable labelling has its part to play, now be truthful, who hasnt at some time had to re-identify which actual antenna goes to the connector that is in your hand?  

Thank you to those at the club room working bee last Saturday. Jobs ranged from repairing, cleaning, gardening and building works. Well done Brendan VK7VIP, Stuart VK7FEAT, Ros, Norm VK7KTN, Lorraine, Bernie VK7BR, Idris VK7ZIR, Andre VK&ZAB and Stefan VK7ZSB.  

Also last weekend Tony VK7YBG, saw a possible break in the weather and quickly organised a party to climb Mt. Arthur to visit VK7RAA on Sunday. This resulted in the re-installation of the repaired DMR antenna and wind generator. Thanks go to Tony, Peter VK7SP, Rosco VK7RC and Andre VK7ZAB for their somewhat slippery climb up and back again.


TestNet and TechNet – Wednesday 11th May. 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. 

Club Tech night – Wednesday 18th May. Held at the NTARC Club rooms, 7.30pm until whenever.

Malcolm White Presentation – 15th June about 20:00 Apart from being a licensed amateur at an early age, and a CW aficionado, the major topic is to be his association with Ray Naughton VK3ATN at the time of Rays pioneering Earth Moon Earth (EME) achievements in the 1960s on the 2 metre band.

Coffee Morning – held every Friday in the NTARC Club rooms. Catch up time is from 10am to noon and we look forward to seeing you all there. These coffee events represent a good opportunity to collect your QSL cards. We currently have cards awaiting collection, so why not pop in and check the QSL box and join us for a cuppa and chat.

FINALLY – A reminder to all members that if you have any items of news you would like added to our weekly roundup, no matter how trivial, then please email them to the Secretary at the following address news(at) all items to be received no later than 5pm on the Friday prior to the Broadcast.

Thats all folks,

Bar B Que and Fox Hunt

A Bar-B-Que and Fox Hunt is to be held on the 14th May 2022.

We plan to start with a Bar B Que commencing at Midday at Legion Park, off The Esplanade behind the Showgrounds at West Ulverstone. 

This is accessed by turning East into Maud Street off Queen Street, following road to river and BBQ facilities. This is a BYO food & drinks, Onsite there are two electric Bar B Ques, toilets, running water and some seating and tables under cover. 

Then at 2pm, if there are sufficient numbers, we will commence the Fox Hunt, which will be along the style of the old-fashioned CB Fox hunts, where the Foxs hides, and then the chasers using signal strength and clues, attempt to locate the Fox. 

The person who finds the Fox, then goes and hides, and we start the chase again, to assist any amateur to participate, it will be run on Channel 50, 146.500 MHz and operate in the Ulverstone Township. We will continue while there are chasers for the Fox. 

If the weather is inclement, VK7EV will be on 2m VK7RMD in the morning, to advise if event is still proceeding, if canceled we may reschedule to the following Saturday.

Local activity on 2M SSTV in Hobart

In the Hobart area there has been some SSTV happening on the local 2M repeater on 146.700 Mhz. The last couple of Thursday evenings at 19:30 local time, the familiar sounds of SSTV in various modes could be heard across Hobart. 

This is an opportunity to experiment with this mode and allows for testing of setup parameters for the many and varied setups from smart phone apps making use of acoustic coupling that managed to achieve very good results up to the SSTV pros that were able to send perfect pictures with their optimised systems. Last week we had 6 locals exchanging various pictures over some 90 minutes. 

There were many things learned and all enjoyed the evening. We plan to make this a regular event if interest continues. So if you are in the Hobart area and want to join in, join us at 19:30 local time and see how you go. 

Of course you can just listen and see if you can decode some of the pictures. Thanks to Ken vk7krj the pictures exchanged can be seen on the internet via the local SSTV reflector at the link on the email edition of the broadcast.

DATV Experimenter's Night

Last Wednesday night Justin VK7TW and Larry VK7WLH demonstrated Inverted or Scrambling Speech. Thanks to Peter Parker VK3YE who dug out an old article about inverted speech using SSB and demonstrated the effect in the above video.

By taking an upper side band and placing it on the low frequency side of the carrier - tuning receiver on the high frequency side of the upper sideband  - low pitches are high and vice versa.

Justin transmitted a 10.119MHz USB signal into a dummy load using the IC-705 and Larry received the signal on this BELKA-DX SSB SDR Receiver by tuning 10.122 LSB. Justin played a recording of an inverted SSB signal which became uninverted and became understandable. Thanks to Larry for bringing in the Receiver for the demonstration.

Hayden VK7HH of Ham Radio DX fame came into the studio and reviewed the latest QST.

Justin then took the audience through the construction of the small vertical 160m antenna results. The antenna is a Drew Diamond VK3XU - short vertical with top loading coil and capacitive hat. Justin showed pictures of the construction method. It repurposes  an Adcock Direction Finding vertical antenna. The top loading capacitive radials at 120 degrees spacing are about 1m long with insulators to create guy ropes. The tuning process is shortening the capacitive radials and Justin showed the NanoVNA results.

Hayden and Justin then promoted the WIA Virtual Conference on 7 May 2022 that happened yesterday and there will be a report in this weeks DATV Experimenters night.

This week we will have more report on how the small 160m vertical performed, a wrap-up of WIA AGM and Conference, some more interesting facts on SSB, an interesting 30m interference issue and much more.

We go out on RF on 445.5MHz DVB-T 7MHz Standard Definition. So, if you have a TV, Set-top box or USB DTV Dongle that you can tune and scan 445.5MHz and you can see the Queens Domain, then you have a good chance of receiving the DATV Experimenter's Night Signal. Look out for VK7OTC. We also stream the nights on the REAST YouTube channel.

Technology News
Chinese astronauts rely on Hytera for safe return

Inner Mongolia, China, saw the Shenzhou-13 spacecraft safely land on 16 April 2022, after six months aboard Chinas newest orbital station in the longest crewed mission to date for the countrys space program. The spacecraft carrying three astronauts landed in northern Chinas Inner Mongolia Autonomous Region, about nine hours after departing from the core Tianhe module of Tiangong space station.

Hytera provided communication support for both the safe landing of the Shenzhou-13 return capsule, as well as the astronauts. With the capsule landing site in Gobi Desert, the largest desert in Asia where cellular coverage can be patchy or even non-existent, the ground rescue and recovery team was in need of a reliable and portable communication system to coordinate and dispatch team members efficiently.

Adopting a Hytera DMR communication system, the team can be divided into convenient talk groups, so only the relevant group needs to hear the call, ensuring smooth and discreet operations.

Inner Mongolia constitutes approximately 12% of Chinas total land area, due to its long span from east to west along the northern Chinese border; yet its population accounts for only 1.84% of the total Chinese population.

Jiuquan Satellite Launch Centre has documented more launches than any other launch facility in China and is the only launch site for the Shenzhou manned space missions. Inner Mongolia is also home to the only two space vehicles landing sites in China.

The Hytera system also integrates GPS function to enable team members to be monitored and located outdoors, while Bluetooth or RFID technology in the radio can be integrated with beacons and RFID tags to provide indoor location fixes. Location technology means users can be quickly located in the case of trouble by pressing the emergency button or if a preset automatic alarm is triggered.

Hytera DMR radio systems can also be integrated with fixed telephony systems, cellular networks, CCTV platforms and Internet of Things (IoT) sensor data to provide access to a wider range of data and to enable communications with people without radios or outside the DMR coverage area.
