23 cm QSO Party
Record Numbers Participating
Last Sunday morning 15 stations participated from Hobart and 2 from up North to produce a new record of 17 stations.
The challenge is to get to 23 on 23 so we need another 6 stations.
Richard VK7ZBX worked Bryan VK7KWB for the first time on digital with signals levels of -15 dB.
And a reminder that during the week if you are feeling socially isolated a group of stations are monitoring 1296.150 FM most of the day ready for a chat.
Just put out a call on 1296.15MHz and you never know who might come back.

Here we are, another week has gone by and isolation continues for us all. We trust everyone is taking care in the current environment, not only looking after your physical health but also as importantly coping with your mental wellbeing.
The challenges confronting us all are not easy but luckily we participate in a hobby that allows you to talk to many amateurs not only in your own State, other parts of Australia but also around the world. How many other hobbies gives you this opportunity? Ironically, at this QTH which is in plain site of most of the NTARC repeaters, we have numerous hand held radios lying around but with all seeming to have flat batteries. I will need to sort that problem.
I have been busy sewing, mind you not always to plan. I managed to damage my big expensive Janome MB4 embroidery machine so have had to put a call in for a new part. Hoping to hear from the company soon to get it back in action. In the absence of the OM, I luckily have the service manual to hand which steps you through repairs required. I will therefore now have to learn how to pull it apart, make the necessary repair and then put it all back together again, as she is too heavy and big to take for service. We have no local service agent but even if we did, I doubt that a trip there would be classed as an essential service. Mind you, given its size and weight, lifting and carrying it must surely constitute physical exercise but seemingly not. As a sewer and hoarder of machines and fabric I find that very amusing but in the circumstances, it falls to my little lot to sort out.
Well enough of the trivial stuff. By now NTARC members should have received a newsletter from Idris VK7ZIR, President of NTARC, bringing all up to date on what we are doing every Wednesday night in lieu of technical sessions held at the club room. A radio TechNet has been established for these evenings. The net commences at 19:30 (7.30pm) on 3.56 MHz LSB and is being hosted by Nic VK7BEE. Yes, Nic wears more than one hat, listeners may recall that he last popped up as our club Auctioneer.
In parallel with the radio net, an online chat server using Discord is being run. This allows participants to join in the forum in ways the radio net may not allow. The Discord net controller is Paul VK7KPA who is available for any questions and assistance in getting online.
To join this group, you will need to receive an invite from the server owner. Once you have that you can sign up to Discord and then join the group with the specific invite provided. Ok? Well the invite link you need is Discord NTARC Tech Net
To use Discord, you can either use it via a web browser or download the application for your system environment, so either GNU/Linux, OSX, iOS, Android or Windows. To download the application, go to their download page: discord download page
As I have yet to join the group I have no firsthand knowledge but I have been advised that last Wednesday the 15th all went well, this being our second night. Once again this occurred on 3.567 MHz LSB at 7:30pm local time (19:30 AEST or 05:30 GMT), with many participants getting involved. Once again all stations had moderate to good signals which improved as the evening progressed.
Next Wednesday we will be on at the same time, same channel so see you there.
John Moyle Field Day contest - the following is courtesy of Andrew VK7DW and he advises the following:-
“In the WIA results from the recent John Moyle Field Day Contest, our Club callsign VK7TAZ is recorded in second place for Six Hour Portable Operation – Multiple Operator (phone-all bands).
Well done and congratulations to all participants.ö
To Andrew and all those other NTARC Members who took part in this event congratulations to you all.
Sadly though, that must be all from NTARC this week. Take care and if you don’t need to go out, stay home and read, listen to music, get on the radio and talk to the world or warm up that soldering iron and get on with those projects. Above all though, please keep well.
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 - it is always good to have something new with which to entertain the troops - then please email them to either of the following addresses ntarc.emails@... or ypmaxwell@... For some time to come, the weekly news will become the medium for informing all about happenings, or lack thereof, in the local amateur radio world. It would be appreciated if any news, no matter how insignificant, could be sent no later than 17:00 hours on the Friday prior to broadcast, to allow its timely insertion into the NTARC segment.
That gives all a chance to get the NTARC segment together and off to Hobart in time for collation into the VK7 Broadcast. Your continued cooperation in this regard will be gratefully appreciated.

REAST Club Virtual Gathering
Last Wednesday night the REAST club held it's first virtual club gathering using the marvels of the Zoom meeting and collaboration software.
The night attracted 16 members and comments about the gathering were good.
We kicked off with a run down from the members of the REAST Committee on what we planning with the zoom trial from Richard VK7ZBX and Larry VK7WLH and then moved to a "What has the REAST Committee been up to" segment with Tony VK7VKT and Hayden 7HH.
There was then a broad discussion on the various virtual gatherings that take place that included:
The 4:30pm Net on the 6m repeater (TX 53.835MHz RX 52.825) each day
There are a group of people who monitor the 1296.15MHz during the day and so you will most likely get someone come back for a chat.
There is the 1296.15 QSO Party each Sunday after the Broadcast that you heard about earlier.
There is the Sewing Circle Net that us now on 3.64MHz from 5:00-6:00pm each day - http://meetthevoice.org/meet-the-voice
There is Dave VK7OB's Trout Net on 7.115MHz from around 5:00 pm each day.
There is a 10m on 28.680MHz and 20m 14.230MHz Slow Scan Television cam hosted here in Southern Tasmania and this is monitored by Steve VK7OO's and Rob VK7MAG's SSTV Cams at:
SSTV Cam 10m - https://vk7oo.tasme.com/sstv10m/index.html
SSTV Cam 20m - https://vk7oo.tasme.com/sstv20m/index.html
There are many Talk Groups on DMR at Global, National (TG-5) and Local (3807) that there is usually someone you can talk with.
We also discussed having short presentations on subjects of interest for our virtual audience and some ideas were floated.
The members of group who usually attend the Wednesday afternoon group were particularly excited about being able to meet face-to-face again via the zoom facility.
We then opened it up for attendees to put in comments and there was some great feedback, ideas and comments.
We thank Hayden VK7HH and the University of Tasmania for allowing us to host the meeting using the Zoom platform.
Considering the positive feedback from members, the REAST committee is looking to setup regular zoom meetings for the Wednesday Afternoon Group so they can meet from 12-3pm on a Wednesday and an email with details will be sent to all club members very soon.
We are also looking to setup a monthly whole of club virtual meeting on the first Wednesday night of the month and we will have someone presenting. Watch your email for more details.
We look forward to seeing you online next time.
73, REAST Committee

New guidelines for non-ionising radiation protection
The International Commission on Non-Ionizing Radiation Protection (ICNIRP) has released new guidelines for the protection of humans exposed to RF electromagnetic fields.
The guidelines cover the 5G technologies, as well as AM and DAB radio, Wi-Fi, Bluetooth and current 3G/4G mobile phones.
ICNIRP Chairman Dr Eric van Rongen said the new electromagnetic field guidelines have taken seven years to develop and are more appropriate than the 1998 guidelines for the higher frequencies that will be used for 5G in the future.
“We know parts of the community are concerned about the safety of 5G and we hope the updated guidelines will help put people at ease,ö he said.
“The guidelines have been developed after a thorough review of all relevant scientific literature, scientific workshops and an extensive public consultation process. They provide protection against all scientifically substantiated adverse health effects due to EMF exposure in the 100 kHz to 300 GHz range.ö
The main changes in the 2020 guidelines that are relevant to 5G exposures are for frequencies above 6 GHz. These include:
the addition of a restriction for exposure to the whole body;
the addition of a restriction for brief (less than 6 min) exposures to small regions of the body; and
the reduction of the maximum exposure permitted over a small region of the body.
“When we revised the guidelines, we looked at the adequacy of the ones we published in 1998. We found that the previous ones were conservative in most cases, and they’d still provide adequate protection for current technologies,ö Dr van Rongen said.
“However, the new guidelines provide better and more detailed exposure guidance in particular for the higher frequency range, above 6 GHz, which is of importance to 5G and future technologies using these higher frequencies. The most important thing for people to remember is that 5G technologies will not be able to cause harm when these new guidelines are adhered to.ö
Other minor changes to the guidelines include:
greater transparency to make the logic and scientific basis of the guidelines easier for the health protection community to engage with;
additional means of assessing compliance with the guidelines; and
greater specification of how to assess complicated exposure scenarios.

AMSA reminds industry of DGPS discontinuation
The Australian Maritime Safety Authority (AMSA) has outlined the feedback it has received regarding the pending discontinuation of Australia’s differential global positioning system (DGPS).
It also has outlined steps that can be taken by DGPS users to move to alternate positioning system arrangements which, it says, will result in improved service.
According to the AMSA website, “DGPS is a ground-based GPS augmentation system, operating in the 285 to 325 kHz frequency range. It was introduced in the 1990s, to improve the accuracy and integrity of GPS information for ships navigating off the coast of Australia.
“A network of 16 DGPS stations … each with a reference unit that generates corrections and provides integrity monitoring for GPS signals, makes up AMSA’s DGPS service. Their location was chosen based on the volume of traffic and degree of risk.ö
The stations compute the difference between the stations’ accurately known position and GPS-provided position and provide users within range of the DGPS radio beacon the ‘differential’ amount, thereby enabling shipboard receivers to improve positional accuracy to better than 10 metres.
However, the nature of the signal means that its range is limited and does not cover all of Australia’s coastal waters or the EEZ.
Thus, for a variety of reasons, the DGPS service is being discontinued. Of particular importance is that the accuracy of GPS now exceeds the accuracy provided by the DGPS service.
In addition, modern GPS receivers incorporate automated integrity monitoring functions to warn the user when GPS information is degraded.
AMSA called for feedback from industry and users regarding the pending discontinuation. Only four submissions expressing concern were made.
Full details of the DGPS and its impending withdrawal can be found on the AMSA website.
