Accessible Radio

By Joe VK7JS

Blind ham, and software engineer, Joseph Stephen VK7JS, from north Tasmania has been extending the open GD77 firmware source project over the past year. This firmware runs on the Radioddity GD77, GD77S, Baofeng DM1801, DM1801A and RD5R handheld radios. Joseph’s version of the firmware, known as AccessibleGD77, to distinguish it from OpenGD77, adds dozens of new features and fixes over and above the official Open GD77 firmware. While it is designed primarily for blind and low vision amateur radio operators and those with dexterity issues, it is also used by many sighted amateurs.

Some of the features it offers over and above the official OpenGD77 firmware include:

    The ability to reorder and delete channels from the radio in the field (without a computer),

    A one handed mode (SK2 Latch) and DTMF latch for people with dexterity issues,

    A more consistent editing experience ,

    Priority channel and dual channel scans,

    The ability to add, edit, and delete DTMF as well as DMR contacts from the radio, and

    An AutoZones feature which optionally adds channelized frequency tables and rules (without having to program them in your codeplug) for popular bands like the Australian UHF CB, international marine, and US GMRS/FRS/MURS/NOAA/rail, and UK PMR446 frequency bands.

    The GD77S, the model without a Keypad, now has a virtual keypad mode and VFO so that many of the features previously only available on the GD77 are now also available on the GD77S model. 

The latest version of this firmware can be downloaded from the “Accessible GD77 Stableö link on the Blind Hams website at:

New beta versions are released frequently and can be downloaded from the “BETA TEST Accessible GD77ö link at the same site.

Joseph is very responsive to new ideas, adding features and fixing bugs. For more information, you can contact him at joestephen(at)

AR Promotion
Amateurs appearing in unlikely locations!

There is a series of innovative television advertisements for the Tasmanian Building and Construction Industry that feature Sergio Giudici projected onto a hydroelectric dam wall.

Sergio is sadly silent key however he was a hydro engineer and an amateur radio operator - VK7SG.

Sergio lived in Landsdowne Crescent West Hobart with a high tower and beam in the backyard.   Richard VK7RO remembers him saying that the council asked for the design figures so he gave them the static numbers, but not the dynamic.   

We suspect he thought they wouldn't be able to understand the latter and there were probably not many outside of the engineering fraternity who could!  Sergio was of course a very big noise in the design of the Gordon system and other hydro electric schemes.

Sergio bought the house next to him in Landsdowne Cresent and Richard remembers VK7AZ suggesting that it was to avoid having to suffer complaints about TVI...HIHI.

The link to the YouTube video of the advertisement is available on the email edition of the broadcast.

Contest News
Oceania DX Contest

The Oceania DX phone contest happened last weekend and this weekend the Oceania DX CW contest is happening from 9 October at 0600 UTC to 10 October at 0600 UTC.

For more information take a look at the website.

There are multipliers for each prefix in Oceania and also different points for each band, creating opportunities for high scores for a few contacts. 

This is also a great opportunity to increase your dxcc countries contact list, as all the stations have their beams pointed to Oceania.

Don’t forget to put in your log for the contests you enter!

Last weekend five club members and their family enjoyed a trip to Sheffield to the Redwater Creek Steam Railway for a BBQ lunch, train ride, and get together. 

The addition of family members  made a nice day of it and the added families made a nice gathering, all appeared to enjoy the trip and lunch. 

The driver for the day was VK7GS Graham, who also gave us a guided tour of the big steam engines and told us their history which was interesting and answered our questions, also about the place doing other jobs we got to say hello to Ross VK7ALH.

Following that some of us went to see Mr Allen Braids commercial radio collection and we were not disappointed with what we were shown. The fun part being confusing instructions on direction which gave us a ride to the foot of Mt. Roland and back, just to go to the opposite end of town and try again.

In all a nice day a very impressive radio collection, and just a light sprinkle of rain that didn't harm us.

This item is being sent by me in the absence of our News Officer Eric VK7EV who was supposed to be with us for the day, but is a guest of the Burnie hospital where he has been for a while, and now showing some progress so to Eric our best wishes for a good recovery and hoping you are home again now.

JOTA Call for volunteers

The Club is operating two JOTA sites, at the Scout Camp at Paton Park behind North Motton , and the Spreyton Scout Hall in Spreyton on Saturday 16th October.

Unfortunately we are short some volunteers and was wondering if there are any amateur’s able to assist. We need one operator from 8am till 4pm at Spreyton, it will be on 2m & 70cm with all equipment supplied.

At Paton Park, it would be great to have two extra volunteers, 9am to 5pm all equipment supplied,  at this stage we will be on 2m & 70cm, but HF if we have more amateur’s attend. We have a HF radio - an FT101E and on site Triband HF beam & OCF Dipole.

There has also been a request to operate the site on Saturday night if we had someone available, this can be on 2m/70cm and/or HF.

If available please contact Eric VK7EV on email: ericvdneut1(at) or mobile: 0418572183

73, Eric VK7EV, JOTA Coordinator

Northern Tasmanian Amateur Radio Club Incorporated

My goodness, we’re nearly half way through the month of October. How time flies. Yesterday, Saturday the 9th NTARC held its October general meeting. I will be able to provide you all with a report next week, but in the meantime I hand over to Idris VK7ZIR to provide you with a summary of events of the Club Tech night held last Wednesday the 6th;

“Peter VK7KPC was an early starter tonight working away in the Radio Shack after lighting the fire and getting the urns going. Peter was in full preparation mode for the upcoming JOTA/JOTI next weekend, and was fine tuning his Echolink equipment in readiness. Also on his agenda was completing the fault-finding on our antenna matcher, which if you remember, had the collywobbles in the metering department. Still a work in progress, but getting closer.

Nic VK7WW attended for a while, taking a break from his Slow Morse instructor role. It was good to see him that evening.

Meanwhile, Ross VK7ALH staggered in with his Heathkit HW101 SSB transceiver. A lovely example of the marque, in the process of restoration. Ross took us through his activities with this radio which has a compliment of 20 valves, or tubes if you’re from the east side of the Atlantic. He has made some modifications to enhance the performance, Thanks Ross.

Idris VK7ZIR had some treasures recovered during a spot of dumpster-diving at the back of a local education institution. They consisted of some old electrical measurement equipment, namely a poly-phase wattmeter and a power factor meter. Both in relatively good condition but judging by the layer of dust and their age, had probably been the victims of not being of used for some time, and therefore no longer required. Also retrieved were some examples of microwave components, in the form of flexible waveguide with dry gas injection ports. Well scored Idris, some repurposing maybe?

Much discussion was had for organising radio equipment for JOTA, testing antennae and working out what would go where in the Clubroom and hall, and the order in which activities would occur, to comply with the current COVID procedures. Everybody was kept fairly busy through the evening and the time passed quickly.

All for now.

73, Idris VK7ZIRö

Thank you Idris for that update. Sounds like another good night out for all.

The following item of interest is from Peter Dodd, VK7KPC in his capacity as Project Commissioner Radio and Electronics, Scouts Tasmania. Peter says;

“On behalf of Scouts Tasmania I wish to thank my fellow Amateurs who are donating their time and in some cases equipment for the upcoming JOTA/JOTI weekend. Huonville and Cygnet Scouts are planning to be on air noon till noon over the weekend with their home grown youth member licensed operators. Amateurs from the North West have been doing upgrade work at the Paton Park Scout camp and should be on air from there and Spreyton. NTARC will be on air from noon till late on Saturday and on Sunday from 10.00 am to 3.00pm.

Also, fairly hot off the press, Huonville Scouts, Lakia using her callsign VK7LJB assisted by Aiva (who is still waiting for her callsign to be granted) won the Top scoring Foundation Licence ALARA member (Trophy) in the recent ALARA contest. The VK7HSD station operated by the boys also received an honourable mention. Thanks to Michael VK7MRS for encouraging these scouts to get their licences and to participate in the contest.

Again thank you

Peter, VK7KPCö 

On behalf of NTARC we also extend our congratulations to Huonville Scouts and also to Michael for his ongoing encouragement of these scouts and generally assisting them to achieve their goals in the field of amateur radio.


TestNet and TECHNET – Wednesday 13th October. TestNet/CW course on 3580 from 7pm till 7.30pm….and a TECHNET on 3567 from 7.30pm till about 8.30pm. Your host for the evening is Nic VK7WW.

JOTA/JOTI 2021 – takes place from 15th to 17th October. Setting up will happen in the afternoon after coffee session Friday 15th. , Peter has lined up a number of events that will be taking place at the Rocherlea Scout Hall, commencing on Saturday 16th at noon and will run through until 8.00pm with the possibility of the Venturers attending after 8.00pm. Sunday 17th October will see groups arriving from 10.00am up to 3.00pm. Plan is they will visit for about 2 hours and the breakdown will see them spend half an hour utilising radio, this will be followed by half an hour on the Internet and a further half an hour outside locating those elusive foxes. Some Skype and JOTI TV will be thrown into the mix, plus 10 minutes being allowed for cleaning up between activities. Also on offer will be how to make a morse code trainer and this activity doesn’t require any soldering, so hopefully the first aid kit won’t need to be opened.

If anyone can assist on Saturday and Sunday, Peter would love to hear from you. He can be contacted by email; dodd.pc(at) or mobile 0408 805 086. 

TECH NIGHT – Wednesday 20th October at the NTARC Club rooms, 19:30 hours until whenever. 


Plenty of notice this time. NTARC will be holding a Christmas dinner on Wednesday 15th December. Venue Mowbray Hotel, meet time is 6.00pm. Tables has been booked under the name of NTARC. Menu is a-la-carte and there is plenty of parking at the rear.

A number of members have already advised notice of attending, obviously eager for another night out.

COFFEE MORNINGS – currently held every Friday in the NTARC Club rooms. Catch up time is from 10.00 am to noon and we look forward to seeing you all.

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.

    Tasmanian Maritime Radio museum and operation

    Much more!

There will be many other general displays and interesting and fascinating things that amateurs get up to as well as a Sausage Sizzle (with onion!), coffee and cake available on the day.

Who could pass up an opportunity such as that!

Please share this event with your friends, family and anyone who would be interested in learning about all things electronic, technology or radio!

The day runs from 9:00am to 3:00pm up at the Queens Domain Clubrooms

See you there.

October Presentation 
Military Radio and Antennas

It was a standing room only presentation from Peter, Kim and Denis last Sunday.

Peter VK7KPC started with FSE-58 section radio from Germany with Helmet antenna - It is crystal locked - mode is FM and runs at 24 Volt - Batteries are a 4 x 6 volt NiCd batteries. Peter shared the Italian schematics with the audience. This radio is cold war era.

We then went across the channel with a Clansman PRC-50 VHF section radio comes with handset or headset, flexible or rigid antenna and is currently on the local 6m repeater transmit frequency. There is a whisper function - low audio level and power. 14V NiCd or C-Cell battery packs.

Peter then showed a Clansman PRC-351/352 VHF manpack with carrying frame - NiCd battery pack - either 4/20W with remote antenna, similar function to the PRC-50. Comes with a hand generator and can link to a vehicle, remote operation, etc. There was also a ground spike antenna demonstrated.

We then went to a PRC-320 HF manpack. Similar batteries and functions to the PRC-351. Has a built-in ATU, comes with a leg morse key, 5/30W power settings with many aerial options. Wire antenna with tunable counterpoises, elements with metric distance/frequency tags. There was also a carry backpack and is only on USB and there are modifications available on the net.

Over to Kim VK7KB - with an Australian AWA A-510 - 1940/50s AM/CW HF valve set in two boxes on your hips with interconnecting cable, crystal locked - four crystals, handset or headset, toolkit, light communicator, many dipole antennas.

Over to an early 1960s Racal SquadCal manpack in a plastic case that actually floats! Came with handset, 5W power, HF AM/SSB/CW and was one of the early manpacks from the UK.

The next manpack was the 1970s RACAL Sencal 30 with synthesised operation - decade dials to set frequency - similar functionality to the SquadCall and was a very popular radio. There were many antenna options and some built in ATU. NiCd battery pack that screws on the base and the radio came from the Royal Australian Air Force.

Move to more modern radios - the QMac HF-90 - HF radios - 1990-2000s - these are built as a system much like earlier radios with sets of antennas, batteries, tuner, etc. 12-28V operation. The ground connections are interesting where the manpack actually capacitively couple to the person carrying the radio for connections to ground.

Kim then moved to an American - General Dynamics GRC-106 mobile radio with RTTY terminal option, 400W power amplifier, receiver/exciter - fully synthesised HF radio. Kim pointed out they use surface connections with no pins. Known as RattRigs by the Americans. Runs on 24-28V built in late 1960-early 70s.

Denis Jackson then showed the back-up radio from boat - Morana - this is 1939 AWA WS-101 ex-military valve radio featuring a door at the base of the radio that opens to access all the eight valves - low HF frequencies and built in morse key. There was the accompanying power supply converter with vibrator DC-DC converter and battery box.

Denis then moved to the 1945 - 122 set - this was a transportable radio with separate vibrator power unit. It has two bands: 2 to 4 MHz and 4 to 8 MHz. The transmitter could be either crystal or VFO controlled.

We then moved to the Domain compound for a demo of some of the accompanying antennas by Peter and Kim.

There is an accompanying video showing high resolution photos of each radio and video of Peter VK7KPC talking about some of the military radios -

A huge thank you to Peter, Kim and Denis for showing us their collection of radios.

73, REAST Committee

November Presentation
Digital Voice Hotspots

REAST's November presentation will be about Digital Voice (DV) hotspots with a focus on pi-star and openspot3.

DATV Experimenter's Night

We started with Ben VK7BEN showing his recent Kickstarter purchase a Storm 2 Power Pack. This is a 100W passthrough power pack. 27,600mAh or 99.36Wh which is within the limits of carry-on luggage on airplanes (remember them!). Can supply voltage from 3.3-25.2V DC Out. It has 2 USB-C and one USB-A+DC. It is a Compact Battery Bank With See-Through Design. We showed the energy control operating system on the small OLED colour screen. The battery bank comes with two connecting cables. Thanks Ben.

Richard VK7ZBX then showed off his very impressive first place in the 6 hour phone section of the John Moyle Memorial Field Day and we discussed the contest, thanks Richard.

We then discussed last weekend's Oceania DX Phone contest and participation. We showed Paul VK5PAS' website and the many contacts he made on 20m, thanks Paul.

Justin VK7TW then showed the inside of a 3.4GHz panel antenna. These are from the Geelong ARC club conversion project. They are basically a 300mm square phased array of PCB patch antennas.

We then showed the latest addition to the Pawsey Supercomputing centre that Andrew Elwell talked about in the REAST April 2021 Presentation

Justin then showed the TAPR WSPR RaspberryPi Transmitter. This is a simple transmitter circuit and low pass filter with the RF and WSPR signal being generated in the RaspberryPi.

We finished the night with a reminder of the November ( Wed 3 Nov) presentation titled "All about Digital Voice Hotspots" with Scott VK7HSE.

A recording of the night is available on the REAST YouTube Channel.

This week at the DATV Experimenter’s night we will have a focus on resonance, review of the latest Low Key Magazine, 3.4GHz experimentation and much more. See you then. 

We get underway from 7:30pm in the Queen’s Domain clubrooms.

Keep an eye on the REAST Facebook Events for more details. Why not come up to the Queens Domain COVID-safe clubrooms and see what we get up to.

And a reminder that 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.
