Northern Tasmanian Amateur Radio Club Incorporated
www.ntarc.net
This month has marched on but I must admit each day is a bit like Groundhog Day, as we grind our way through this seemingly e
ndless social-distancing regime. Not that I can really recall the Groundhog Day movie but somehow the mental picture the title
conjures up seems apt. If I am mistaken in my recollection of the movie's title, please accept my apologies and insert your own
choice of title. Nobody will be any the wiser.
As mentioned last week, the Club is really looking forward to Stage 2 again coming into effect as that is touted to allow gathe
rings of up to 20 people to meet indoors, so hopefully after 15 June we may be able to reopen the clubrooms for coffee mornings
. We will keep you posted via this weekly Broadcast segment as we move forward towards that happy happening.
As for your scribe, the NTARC news segment will be even shorter than in recent weeks, as I have nothing newsworthy to report fr
om the home front and nothing about club happenings from further afield has reached me.
The one noteworthy development from further afield is that at long last, the ACMA has apparently called for submissions about h
ow it might go about making the 60 metre allocation available to Australian amateur radio operators and a number of options are
being canvassed. This will no doubt have been featured in the National news segment from the WIA, so if you have an interest i
n seeing VK obtain access to this additional HF band, I suggest you take a look at the WIA and/or the ACMA websites and let the
ACMA know how you feel about this issue. I understand that there are some tricky considerations involved, not least the narrow
width of the possible allocation and the limited power likely to be permitted, not to mention the ongoing but surely time-limi
ted non-amateur uses of that band at present, particularly in Queensland. Whatever, here is a very limited chance for you to ha
ve your say.
On the local front though, while face to face sessions remain beyond the pale, we still have the Wednesday night Tech Session 8
0 meter and Discord nets running, so Ill now hand over to Nic VK7BEE, our Net Coordinator to give you a run down on last Wed
nesday 20th May Tech Net session:
THIS WEEK IT WAS A NIGHT OF "POURING RAIN, THUMPS BANGS AND STATIC CRASHES!"
The net had 10 stations. Conditions were poor with high levels of static crashes and heavy rain!
The usual tests on the QRP frequency of 3.580 MHz at 19:00 AEST had two stations, Nic VK7BEE with 3.8watts CW and Kevin VK7HKN
initially with 1watt, then up to 4.7 watts LSB. The circuit and a photo of Nic's QRP transmitter was posted on Discord. Some op
erators again used SDRs via the internet to receive because of high local noise, using their rigs to transmit on. Robin VK7RH g
ave Nic VK7TAZ a report of 5 and 7 from an SDR in New Zealand. He switched to a local SDR, then one in Melbourne. However, the
Melbourne SDR suddenly disappeared!
“DISCORD” online communications with Paul VK7KPA as host of the NTARC Tech Net Group, was very well used to give signal and
condition reports this evening.
Eight VK7s joined Discord, some also on the TechNet at the same time, sharing pics and information whilst on-air.
Nic VK7BEE took over as VK7TAZ Net Control of the NTARC Tech Net Group at 19:30 AEST on 3.567 MHz LSB.
Kevin VK7HKN again with a very good QRP signal running 4.7 watts, and a picture of his loop antenna posted on Discord.
Ross VK7ALH, using his magnificent Heath Kit Marauder HX-10, a very early SSB transmitter from 1964, came and went suddenly! He
later reappeared using his TS950, telling us a problem capacitor caused his disappearance. But on the bright side he has locat
ed a companion Heath Kit Mohican Receiver, which is on its way from Canada!
Phil VK7ZPD had a great signal, and he is now building his QRM eliminator to combat power line noise.
James VK7JAM had very low signal strength and posted a message on Discord saying he will not stay on due to static QRN but will
try and make antenna improvements.
Andrew VK7DW, aka Mr Satellite, has had great success with SSB contacts via satellites using the VHF and UHF uplinks and downli
nks. Congratulations Andrew!
Kerry VK7PAK with his IC7400 at St Leonards, called in to give reports.
Peter VK7KPC had very low signal strength. Difficult to copy due to the conditions.
Peter VK7PD posted a circuit and picture of his 70cm to 13cm transverter/amplifier wiring, and told us how he was going to make
a VK7 presence on 2.4 GHz for the Field Day on June 20th and 21st. Peter says that he is willing to help any amateur wishing t
o use these bands.
Peter VK7ZPE called in for a quick signal report.
Nic closed the net after two “rounds” due to poor conditions after thanking those stations who called in. He also said he w
ould be trying out AM on 3.580 MHz before the TechNet next week, and would also try AM during next week's TechNet on 3.567 MHz.
73 and keep warm and dry
Nic VK7BEE.
Thanks Nic for that update. Once again it appears another interesting night had by all.
Once again, this must be all from NTARC for this week. As we have been saying for the past month or more, 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 iro
n and get on with those projects.
Above all though, please keep well and keep as watchful an eye on the wellbeing of your immediate circle as is possible in the
circumstances.
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 followin
g addresses
ntarc.emails @ gmail.com or ypmaxwell @ bigpond.com
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.
73, Yvonne VK7FYMX, Secretary NTARC Inc.

DATV Experimenter's Night - Working from the Shack #7
Last Wednesday evening saw an online interview with Paul VK7FPCL. Born in America, Paul's lifelong interest in electronics and
eventually radio began at an early age with his mother working for many high-tech companies like Cal-Tech, JPL, MRI and Aerovir
onment. Paul visited Oldwig von Roos who was a scientist at JPL and he was a ham radio operator. Paul had Electronics sets, mad
e a crystal set and played with many items to find out how they worked.
Paul at working age joined the US Navy as a Fire Control Technician. This role on a ship is to use a mechanical calculator to w
ork out the azimuth and elevation to deliver a payload and this supplemented his interest in computers. Paul eventually visited
Hobart on a Navy ship and a year later hooked up with a local woman and ended up marrying her further year later.
He left the Navy and worked for a company called Aerovironment on installation of sampling equipment and studied digital electr
onics. Paul moved to Hobart in 1990 and started working for Management Technologies (the Apple Shop at the time). Then, 9 years
later, moved to network management at Friend's School where he is now.
His interest in electronics and radio then took off with hobby electronics and building some projects including an Electronics
Australia power supply. Paul bought an SDR and started playing with it and came up to REAST and found his interest in radio exp
loded!
Paul recently got his Foundation Licence as VK7FPCL. With encouragement from Richard VK7ZBX, Murray VK7ZMS and Ben VK7BEN, Paul
participated in the RD Contest. The contest provided some of Paul's first contacts and he took out the Foundation Section in 2
019.
Paul talks in the interview about his experience as a recent foundation licensee and contesting along with his involvement with
the REAST club.
A huge thank you to Paul for his time.
This week we have an interview with Peter VK7PD from the North. Peter is a lifelong educator and microwave experimenter and has
put a lot of work into an accompanying powerpoint that he will show during the interview. So, this is one not to be missed.
We get underway from 7:30pm and we will be taking questions via Repeater Two (146.700), DMR Talkgroup 3807 and the Youtube Chat
channel.
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 Do
ngle 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 E
xperimenter's Night Signal. Look out for VK7OTC. We also stream the nights on the REAST YouTube channel and Facebook.

We get underway with the DATV Experimenter's "Working from the Shack" Night #8 from 7:30pm this Wednesday 27th.

TECHNICAL ARTICLES
Private cellular networks growing in popularity
The popularity of private cellular networks is growing among enterprises globally, with initiatives in 15 countries currently,
according to tech market advisory firm ABI Research.
This includes arrangements for enterprises to acquire spectrum from the regulator, as well as spectrum assets held by MNOs that
focus entirely on providing private cellular networks for enterprises.
Either way, private cellular network operators are a growing threat to traditional telcos, said Leo Gergs, Research Analyst for
5G Markets at ABI Research.
"With the very economic pricing, we will see even more enterprises expressing interest, as the ecosystem for 5G connectivity ma
tures," he said.
"Specialist operators " will disrupt the market by offering business models to enterprises that follow an ‘everything-as-a-se
rvice" (XaaS) approach," Gergs added.
"Since all these specialist network operators have a system integrator background, they have the vertical-specific knowledge ab
out requirements, pain points and deployment complexity.
"These specialist network operators, therefore, enjoy an incumbent advantage over traditional telcos in bringing connectivity t
o enterprises."
While large enterprises might have the manpower and the necessary financial resources to manage the network on their own, "Glob
ally, there are only round 10 million enterprises with more than 500 employees, while there are more than 700 million small and
medium-sized enterprises with up to 500 members of staff, which will look for third parties to manage a private cellular netwo
rk," Gergs said.
"To realise this immense revenue opportunity with SMEs, network operators need to leave their comfort zone and offer appealing
solutions to them, which are fundamentally different from the offerings in the consumer domain," Gergs suggested.
These should centre around monetising services such as the provision of a particularly high bandwidth, certain low latency or t
he provision of additional capabilities like network slicing.
"ll these costs should be captured in regularly occurring subscription fees to keep the amount of upfront financial investment
as low as possible," Gergs concluded.
These findings are from ABI Research's Private Wireless Spectrum Tracker market data report.

AMSA issues float-free EPIRB reminder
By Amy Sarcevic
Float-free EPIRBs will be required on certain types of commercial vessels from 1st January 2021, and operators are being urged
to upgrade or purchase new units now to prevent a supply shortfall and meet their obligations in time.
Australian Maritime Safety Authority Chair, Stuart Richey, said the cost of a float-free EPIRB pales in comparison to the cost
of an unassisted incident at sea.
"A float-free EPIRB retails for about $800 the lives of your crew and passengers are worth far more than that," Richey said.
New Zealand mandated float-free EPIRBs in January 2019. Just two months later, three commercial fishermen were saved when their
boat was swamped by a wave and their float-free EPIRB activated.

Victoria's SCC reaches eight-month milestone
By Amy Sarcevic
Victoria's primary control centre for managing state emergencies, the State Control Centre (SCC), is celebrating a long stint o
f operational success after eight continuous months of activation.
At the outset, in September 2019, the SCC was staffed to support interstate deployment of Victorian firefighters in NSW and Que
ensland. But its operations haven't slowed down, with disasters such as COVID-19 and extreme weather events demanding its ongoi
ng input.
Since September, more than 13,000 staff have been deployed to support the SCC's key functions including intelligence, public in
formation and logistics, as well as supporting the State Response Controller, the State Air Desk and Room Management, among oth
er key roles.
Emergency Management Commissioner Andrew Crisp said that, given the range of emergency incidents under its remit, the SCC and i
ts members have had to be agile and diligent in their efforts to keep the community safe.
"The SCC has been stood up for more than 200 consecutive days, which has never happened before in its history,” he said.
"Every member of the team has played a part in keeping the community safe not only the Victorian community, but also our inter
state colleagues and communities too and I sincerely thank you for that. It's been an incredible team effort."
