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)skymesh.com.au

NEWS FROM THE NORTH WEST
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)bigpond.com or mobile: 0418572183

Northern Tasmanian Amateur Radio Club Incorporated
JOTA/JOTI 2021 has arrived and as we all know, it is the world’s largest single Scout event, these days taking place both online and over the air. As this news goes to air many amateurs around Australia and across the world will be busy assisting scout groups. Next week I’m sure our member Peter Dodd, VK7KPC, in his capacity as Project Commissioner Radio and Electronics, Scouts Tasmania will provide us all with an update of events that occurred in Tasmania and hopefully some greater detail on the activity at the NTARC JOTA/JOTI station.
Last Saturday, 9th October NTARC held its October general meeting. We had a good attendance and the agenda was again worked through in a timely manner. The main discussions in general business was the issue of the 2022 Membership fees. A requirement of our Rules is that the existing fees remain in place until specifically varied by a majority vote at a General meeting, with that vote ordinarily to be considered at such a meeting in the final quarter of each Club year.
Idris advised that the Committee has discussed this matter and felt that for the period 1 January to 31 December 2022 membership fees should be increased by the amount of $5, which would mean that for a full voting member the current fee of $35.00 would be increased to $40.00 but the fee of $5.00 for each family member would remain. The treasurer noted in his report that there have been significant increases in operating costs during the year, not matched by similar increases in revenue.
Idris then sought any questions or comments about this item and the general consensus was that this was a reasonable increase. A motion to that effect was put to the members and the vote by show of hands was unanimous. Renewal notices will be sent out in November to the address held on the membership register but if you wish to renew your fees before then please note that the NTARC website has a renewal notice and our bank details.
The meeting was followed by a presentation by member Ian Hart VK7IH. For those that don’t know him, Ian is a Paramedic with Ambulance Tasmania and volunteered his time to come along and give a presentation on how to use the Automated external defibrillator (AED), now a fixture in the NTARC clubrooms. His presentation ran for about an hour, as he stepped through the process of operating the unit. As Ian said, the machine does all the hard work for you, telling you what to do, when to do it and insists on the required breaks when appropriate. No, I can assure you we didn’t practice on a live body. The machine is so smart that if it detects that patient doesn’t need defibrillation it simply won’t do it. A very interesting and vital presentation and for those in attendance we now know how to use the box on the wall. If you haven’t noticed it, it is located on the wall, right hand side of the door leading into the kitchen. Great to have it on hand. Hopefully we never have to use it but then again, much of our membership is in age groups where this is more likely, so it is undoubtedly better to be prepared.
The presentation was followed up with afternoon tea and a chat.
TECH NIGHT – Wednesday 20th October at the NTARC Club rooms, 19:30 hours until whenever.
TestNet and TECHNET – Wednesday 27th 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 will again be Nic VK7WW.
Equine Endurance Event – The NTARC Safety Communications Team has been asked to provide safety comms at the Tasmanian State Equine Endurance Championships at Merseylea on the 13th of November. The rides will be 160km, 95km and 50 Km. The 160km is a 24 hour ride that starts at 00:00 hours Saturday. We will be providing Base Comms, checkpoints and RFID tracking. We will need additional crew members to handle this event so if you can spare some time on that Saturday why not pop down to Merseylea, a pleasant 1 hour or so drive from Launceston and utilise your radio skills. Please advise if you are able to assist by emailing secretary(at)ntarc.net or catch up with Idris at a coffee session.
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. Please RSVP the secretary at either of these email addresses news(at)ntarc.net or ypmaxwell(at)bigpond.com or jot your name down on the sheet next to the sign in register on a Wednesday night session or coffee morning. We will need to confirm final numbers with the Hotel on Tuesday 14th December, so please ensure you get your name on the list before that date. 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.
Just a friendly reminder, please demonstrate your appreciation of all the effort that goes into operating the club, its facilities and the other services we provide, especially in these abnormal and very trying times, enjoying the company, coffee, biscuits and cake, by leaving a gold coin or two, or even a small bank note, in the jar to assist in our on-going operations.
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 me at the following address news(at)ntarc.net all items to be received no later than 17:00 on the Friday prior to the Broadcast.
Your continued cooperation in this regard will be greatly appreciated.
We will bring you all such contributions next Sunday morning.

DATV Experimenter's Night
Last Wednesday night we started a series of articles on resonance.
We started with some resonance happening with some antennas at the QTH of VK7TW. Justin VK7TW played an audio recording of the resonance setup by the wind.
We moved to what is the definition of resonance namely it describes the phenomenon of increased amplitude that occurs when the frequency of a periodically applied force is equal or close to a natural frequency of the system on which it acts. Natural frequency - is the frequency at which a system tends to oscillate in the absence of any driving or damping force
There are some famous examples like the Millenium Bridge 2000, before that there was the Broughton Suspension Bridge 1931 from which British soldiers always break step when marching across a bridge, Angers Bridge in France 1850 and of course the Tacoma Bridge Washington 1940. - myth busters
We moved to Ernst Florens Friedrich Chladni German Physicist and Musician - Father of Acoustics and the calculation of the speed of sound in different gases - he did go on to found the study of meteorities called meteoritics!
Chladni invented his plates which he resonated using a violin bow - we have a slightly different electronic method of vibrating the plate - series of nodes and antinodes across the plate - size and shape combined with different frequencies define the resonant patterns of the salt the plate - the salt self-organises to the nodes and antinodes on the vibrating plate.
Justin then demonstrated salt on the plate and different frequencies on his homebrew Chaldni plate.
Next week we will explore RF resonance and how it helps us in Amateur Radio in a bit more detail with some interesting hands on equipment. Stay Tuned!
We then did a review of the Sept 2021 Low-Key Magazine.
We moved to 3.4GHz SG-Labs Transverter tests update with the comparison of the large and small austar gridpack antennas with 3.4GHz feeds.
Justin started with photos of the small Austar gridpack and got results similar to the GARC 300mm panel antenna - FM quietening with signal reports of no more the S3 although the QSB was significant.
Justin then moved to the larger gridpack - lent from Steve VK7OO and significant improvement - full quietening however QSB peaks were above 5/9 - definite improvement. The directivity was also sharper with not much azimuth movement to lose full quietening.
I went back to the small Austar dish and confirmed my original results.
Richard VK7ZBX showed his 23cm and 3.4GHz setup via photos, thanks Richard.
STOP PRESS - REAST will be hosting the half day virtual conference with a theme of Antarctic Gateway - more to come in the near future.
We finished with a reminder of this Saturday 16th October which is the REAST Open Day and our November presentation on 3 Nov is 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 RF resonance, more 3.4GHz experimentation and much more. Dependent on what happens with the lock-down it may be coming to you from the Queen’s Domain clubrooms or the QTH of VK7TW.
We get underway from 7:30pm.
Keep an eye on the REAST Facebook Events for more details.
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.
