One week of daylight savings has just passed. Hopefully all have now adjusted and are coping with the change, even if some may have missed last Sunday’s broadcast, having forgotten to put the clock forward one hour?
We have no new items of a general nature this week but thankfully last Wednesday was Tech night at the club rooms so without further ado, we will hand over to Idris VK7ZIR to let us know how things went,
“We kicked off at about 07:00 for an early start, with all services fired up for when members started arriving. Soon the room was full of conversations and coffee.
Discord was up and running on big and small screens to link our Club room session with the 80m Tech Net frequency, monitored by Nic VK7WW aka Double Scotch, for those who couldn’t attend. Peter VK7KPC brought along his AN/PRC64 covert military radio set, manufactured by the Delco Division of General Motors. This was demonstrated by Peter, operating on the 80m Tech Net. Paul VK7KPA, our Discord master, had set up a Tech Net audio channel on the Discord session, so we were getting a time delay between that and Peter’s transmissions! His PRC64 came in a field pack with its own antenna components and a compact Morse key, which Peter ably demonstrated. Thanks Peter for an interesting presentation.
Meanwhile, Peter VK7PD brought in a kit, obtained from VK5TM which was a noise canceller. One of these kits had previously been built by Phil VK7ZPD, and apparently delivers good results. Peter set to work slaving over a hot soldering iron on a spare bench, and completed the PCB population in good time. His next move is to mount it all in a suitable diecast enclosure, which we will see next time. We’ll get you a better light for your next project Peter!!
Ross VK7ALH brought in a Kenwood TS2000 for some operating instruction. Thanks Ross.
André VK7ZAB was working on fox transmitters to be used in the coming JOTA/JOTI for the ever popular fox hunting event. He gave interested onlookers an impromptu talk as he was working. Well done Andre’. We hope the weather is kind for this activity on the day.
With the COVID-19 room capacities posted on every door, there was a constant rotation of bodies to the Radio Shack and the kitchen. Quite amusing at times, but necessary precautions for these sessions and for JOTA.
All for now,
73, Idris VK7ZIRö.
Thanks Idris, it is great to see a good roll up attending these nights.
Now we hand over to our Technet Coordinator Nic VK7WW to let us know how things went on the No formal Net of last Wednesday night,
“The TestNet started on 3580 at 7pm local time with FOUR stations.
Nic VK7WW (The Major, Double Scotch) - was the sort of net controller...whipping the troops to order!.....and was joined by:
• Peter, VK7KPC/P from the NTARC Clubrooms on 2w of AM and CW using an ex SAS 64 Set, which was crystal locked on 3580;
• Graham, VK7KT from Burnie, also on AM; and
• Roy, VK7ROY from Birralee, again on AM!
Suddenly it was an AM Net! Band conditions were excellent with signals at Nic’s Legana location between 5/9+15 up to 5/9+40.
No formal TechNet followed at 7:30pm local time on 3.567, with the following 7 stations having a group discussion:
• Nic, VK7WW
• Peter, VK7KPC/P as VK7TAZ
• Graham, VK7KT
• Roy, VK7ROY
• Paul, VK7KPA
• Phil, VK7ZPD; and
• Rodney, VK7HAM.
Details of the technical discussions became CLASSIFIED by the Major this week - all because of Idris’s tutu! Those who want to gain some insight, need to log into Discord! If you haven’t got access please contact President Idris, VK7ZIR, or Paul, VK7KPA.
The variety of topics and photos on Discord was a sight to behold - but classified!
And now for a separate news item:
Nic VK7WW has been running the special event station VI75WW2 during the last week! It was a great success. (Sponsored by the Tablelands Radio and Electronics Group and Fred VK4FE in Far North Queensland.
20m and 15m propagation was very poor, so Nic worked 160, 80 and 40m, with the majority on 80m - total of 187 contacts.
VK1,2,3,4,5,6,7 but no VK8 or 9s, 14 ZLs, Several US stations on 40m, but the best DX (and to Nic, most surprising) was U.S.A. from Rhode Island, who gave Nic 5/8. Also, a contact into Norfolk, England 5/7 both ways - both on 80m LSB!
Nic says it’s his Double-Extended Zepp for 80m that did it!
But quite apart from the number of contacts, it was very interesting to contact ex-military and serving members. Then there were also the stories of family members in WW2. One particular poignant contact was with a radio Amateur who is the son of an Italian POW, who was placed at Korumburra (Vic) during WW2.
eQSLs are now available on silvertrain.com.au
Nic also submitted a log today to the Oceania SSB log people, as he gave out about 30 numbers with the special event call VI75WW2.
Thank you to all who participated, 73 Nic VK7WWö
Thanks Nic. We turn now to,
Future events
Fortnightly TechNet – Wednesday 14th October. Nic VK7WW will once again be in the chair hosting a “TestNetö on 3.580 MHz at 19:00 local time, with the TechNet for NTARC following on 3.567 MHz at 19:30 local time. Paul VK7KPA will be hosting the accompanying Discord session on the net.
JOTA/JOTI 2020 - Scouts Tas JOTA/JOTI at NTARC Club rooms Rocherlea on Saturday17th and Sunday 18th October.
Physical set-up will start following the coffee morning on Friday 16th, with a shuffle of seats and tables. HF radio etc will be placed on a table just outside its normal home and connected to the antenna system. This is because of scout safe requirements that youth members should be in open areas when interacting with adults. DMR and VHF and UHF transceivers will also be set up in the main room to access repeaters plus a dedicated 2m radio for echolink access to VK7KPC-L local node at Rocherlea.
Tables in the large hall should have been set up for the JOTI activation by then taking into account physical distancing requirements. Northern Area Rover Crew are again providing staffing for this operation along with some Venturer scouts who are planning late night operation. The large screen Skype terminal will also be in operation.
2m fox hunting will also be run in the neighbouring bushland again with foxes being in cute stuffed animal finger puppets.
Billy carts will also be running, probably on the opposite side of the oval.
Room occupancy signs have been revisited for the weekend plus movement direction signage. More hand sanitising stations (thanks to Ian VK7IH) to be set-up along with signage.
Finishing touches will occur on Saturday 17th from about 9am with first visitors already booked in at noon. Radio section will be operational until Saturday evening and will restart Sunday at 10am. Last groups will depart just after 3pm.
No BBQ this year but some soft drinks plus coffee and tea being available.
We have 2 operators, Stuart VK7FEAT and Stefan VK7ZSB available to operate from Tamar Scout hall, but we are still waiting on required operating time info. They should be on echolink via Rocherlea and possibly HF.
Another station at Spreyton Scout Hall is planned with Andrew VK7DW as operator for several hours on the Saturday morning for the local Joey Mob. Hoping Shirley VK7HSC may also be able to attend, but if not, she has indicated that she may be on air to talk to scouts.
See you at the hall, even if only for an hour or so.

Peter VK7KPC, JOTA/JOTI Coordinator.
Fortnightly Tech Night – Wednesday 21st October at the NTARC Club rooms 19:30 hours until whenever. Continuous tea and coffee, although a gold coin donation for the evening would be appreciated. The Discord on-line session that normally accompanies the TechNet 80 meter event will also be alive, Murphy permitting, to allow members who cannot be present in person to continue their participation via that medium.
Equine Endurance event - State Championships Santarena Park, Scottsdale November 20-21. Rides over the days will be a 160km, 95Km, 40km and 15km. The 160Km ride is a 24 Hour ride.
We will need additional crew members to handle this event. Please advise if you are able to assist please email Norm VK7KTN: safetycomms.ntarc @ gmail.com or catch up at coffee session.
Coffee mornings – currently 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.
Please remember that aside from the good company, freely offered philosophical views, maybe less than expert political analysis, tall tales, funny stories and genuinely good fare on offer, these coffee events in the past have been normally a good opportunity to collect your QSL cards. Currently we have a few cards awaiting collection from past deliveries.
As I remind all each week, 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 and leaving a gold coin or two, or even a small bank note, in the jar to assist in our on-going operations.
Once again though, this must be all from NTARC for this week. Please bear with us as we attempt to bring club life back to normal, while balancing the need for continuing caution and with all complying with the social distancing requirements.
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 either of the following addresses ntarc.emails @ gmail.com Please note that it would be appreciated if any items for the weekly news could be sent in Times New Roman, 12 pt Font format.
For some time to come, with the exception of the occasional club emailed newsletter, the weekly broadcast news segment will continue as 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.
We will bring you all such contributions next Sunday morning.
73, Yvonne VK7FYMX, Secretary NTARC Inc

October REAST Presentation Night
Steve VK7OO took the audience through his obsession (his words!) with SSTV and SSTVCams.
Steve started with his amateur radio journey and him coming to VK7 as VK2XOR which was a limited callsign in VK2. He became VK7XOR and then with the licence realignment he became VK7OO.
Steve started SSTV back in 2007 and the went on to explain what a SSTVCam actually is. Basically it is a person who receives the SSTV signal and then uploads them to a website.
It took Steve 24 hours to work out how to do this and getting a website up and going and the rest is as they say is "history"!
Steve has updated his website a few times to make it more contemporary.
He then went into what you need to run a SSTV station and the what you need to run an SSTVCam and the additional equipment and software.
Steve then went into the Challenges of SSTVCams including dedication and uptime, bandwidth, receiver sensitivity, FTP access, QRM & QSB and moving house!
How much power do you need? Not much - 10W can certainly get you out and heard.
Steve has sat on one frequency for 13 years and related his experiences - including a map of VK propagation.
Steve's favourite contact was with VK5HJS and best DX was FM5CD in Martinique.
Working SSTV from the ISS is easy and Steve explained how.
Steve then went into the antennas he used overtime from a G5RV, Beveridge, EFHW and magnetic loop.
Steve then went into his experiments with magnetic loops including building a VK5SFA 160/80m mag loop.
Steve showed his VK5JST Pex-Aluminium-Pex (gas pipe) loop from the AR magazine published design. Steve showed the pipe and the trumpet capacitor design and calculations to match the loop.
Steve summed up with SSTV in 2020 and took questions from the audience.
Thanks Steve.
The presentation was recorded and will be available soon on the REAST YouTube Channel.

We apologise for those who expected a streaming channel - things went a bit wrong with the streaming and didn't happen on the night!

TECHNICAL ARTICLES
Security for mobile and wearable devices
By Jonathan Nally
Potential security vulnerabilities inherent in smart devices being used by first responders are reviewed in a new NIST report.
First responders around the world are making increasing use of the latest mobile communications and computing technologies. Sometimes this usage is officially sanctioned and formally delivered, while at other times individual first responders might make use of personal equipment.
In either case, many newer technologies being employed are consumer grade rather than mission-critical grade. Examples include Bluetooth headsets, body cameras, smart glasses and vital-sign monitors/body sensors.
The employment of such devices, while enhancing operational effectiveness, also carries risk in the form of potential security vulnerabilities.
That risk will only increase as more countries deploy public safety broadband networks.
To analyse that risk, the US National Institute of Standards and Technology (NIST) undertook a review of public safety mobile and wearable devices and their current capabilities, assessing them against the security objectives identified in NIST Interagency Report (NISTIR) 8196, ‘Security Analysis of First Responder Mobile and Wearable Devices’.
NISTIR 8196 was produced during a previous study to understand the security needs of smart devices for first responders.
“The ultimate goal of this effort is to provide guidance that enables jurisdictions to select and purchase secure devices and assist industry to design and build secure devices tailored to the needs of first responders,ö the review’s authors said in the new report.
“As with any new technology, there are security concerns, such as the vulnerabilities and threats to their users. In the case of public safety there are concerns that exploits of vulnerabilities may inhibit first responders from performing their duties and put their safety at risk.ö
The report assesses the various use cases of public safety mobile and wearable devices, reviews known attacks on such devices and includes information from interviews with public safety officials.
“Mass production of mobile and wearable smart devices makes it easy to find and buy any device that may meet one’s wants and needs. Technology is primarily produced for the general consumer or enterprise and not specifically designed with public safety in mind,ö the report says.
“This could lead to potential repercussions if the appropriate device is procured without consideration of the security and safety of first responders.
“When it comes to selecting mobile and wearable devices, there is little security guidance that focuses on the particular needs of public safety. During an emergency, a first responder should have some assurance that their devices are reliable and secure.ö
The report shares a “high-level overview of the current capabilities of public safety mobile and wearable devicesö and gives an insight into the security capabilities of today’s devices. It also provides guidance for procuring and designing secure mobile and wearable devices specifically for public safety.
Additionally, it includes a list of tests developed to analyse public safety mobile and wearable devices, with each test providing an overview of the outcome and the analysis derived from observation of that outcome; and a collection of best practices and guidance for the use of such devices.
You can read the report at https://csrc.nist.gov/publications/detail/nistir/8235/draft.

Satellite-enabled connectivity for energy, utilities and mining
Inmarsat, AST and Harvest Technology Group have signed an agreement that will give the latter’s customers the ability to remotely monitor assets, coordinate site surveys and conduct maintenance operations using real-time video and audio transmitted via ultra-low-bandwidth satellite communications.
Harvest’s Wearwolf wearable headset and ‘data-anywhere’ solutions can transmit high-quality synchronised video and audio between technicians, engineers and site managers who may be in widely separated locations — even on different continents — via Inmarsat’s Explorer 710 BGAN (Broadband Global Area Network) terminal.
Steven Tompkins, Director of Sector Development at Inmarsat, said that the coronavirus pandemic has meant that “there has never been a greater need for affordable solutions that help organisations collaborate, work together and improve operations, no matter where they are locatedö.
“This alliance will not only allow for the implementation of existing technology, but will further fuel the innovation for future cutting-edge communication initiatives,ö said Harvest’s Managing Director, Paul Guilfoyle.
