ANZAC Day 2022
Winnie the War Winner

World War II saw the need for skilled radio people to operate and maintain defence radio equipment. Amateurs filled this need and many helped in the creation of a communications infrastructure for the Australian Defence Forces.

One such person was Signalman Max Loveless VK7ML SK. He was an amateur before WWII and became involved as a signals operator with "Sparrowforce" on Dutch Timor with the AIF.

Fighting as guerillas against overwhelming odds, deficient in supplies and out of touch with Australia, it was imperative for the small force to re-establish communications with the mainland. 

Members of the 2/2nd Australian Independent Company, fortress signals section and members of 8th Division Signals, pooled their resources to build a set capable of raising Darwin.

After many trials and much revision a radio was devised from pieces of other sets and from parts scrounged among the troops or stolen from the enemy and on the 20th April 1942, Darwin was made aware that the Australians in Timor were alive and well. The bulk of the work was undertaken by Signallers Max Loveless and Keith Richards, assisted by Jack Sargent and John Donovan.

The set was affectionately named "Winnie the War Winner" after Winston Churchill and after several days of answering some personal questions – like  "What is the Christian name of Jack Sargent's wife?" The signaller at the Timor end was Jack Sargent and he sent back the message "Kathleen", which established the bona fides of the original message and Darwin was convinced of the authenticity of the signals, and was able to arrange for much-needed supplies to be delivered to the isolated troops.

A wonderful story of ordinary people doing extraordinary things in time of war.

There is the original Winnie the War Winner transmitter on display in the Australian War Memorial in Canberra and there is a replica that Barry Riseley VK7RS (SK) made in the Anglesea Barracks Military Museum in Hobart. Barry worked with Max Loveless in the PMG.

Northern Tasmanian Amateur Radio Club Incorporated

At the time of writing, the NTARC Safety Communications Team is at Wattlewood Park, Sassafras on an Equine Endurance Ride. We traveled down Friday morning and have established the Ride Base, set up a 2 meter and 70cm repeater for voice and data communications and are in the process of testing communications to field check points. The rides will be 160km, 85km, 50km and 25km spread over the two day event. The first of the rides start at 03:00 Saturday morning, it looks as though it is going to be a cold start.   If it is Sunday when you hear this then hopefully we are packing up and making our way back to Launceston. An update to follow in the next broadcast.

Now over to Idris VK7ZIR to bring you up to speed on the happenings at last Wednesday club Tech night; “Peter VK7KPC was first on the scene and had the fire burning welcomingly when we arrived. That completed he was off conducting measurements on the clubs multi band vertical antenna. He selected the 80 metre band for his test and measurements using his RigExpert analyser. This obtained the values of resistive and reactive values at a particular frequency. Peter patiently took groups of club members through the use of the software to calculate passive component values needed to achieve a match and the results were shown graphically as a Smith Chart. The name of the software is SimNEC. For further information see the link that is available in the text version of the broadcast. http://www.ae6ty.com

Thank you Peter for your patience and enthusiasm. He also brought in a mystery item, a weighty brown wax covered box about the size of a modern mobile radio… On turning it over the manufacturer was revealed as “Crompton and Parkinson” of South Shields in the United Kingdom.  On further examination it had a list of voltages, 135, 67.5, 6 and1.5 Volts. Considering the evidence it turned out to be a multi voltage battery for a military valve radio. Peter confirmed it was the battery pack from an A41 LarkSpur type Man Pack field radio. The weight of the battery constituted half the weight of the combined radio set. It could also be used in the American equivalent PRC8, 9 and 10. All capable of operating in the amateur VHF band.

Also on show was a Dentron GLA1000, a 500Watt HF linear amplifier brought in by Ross VK7ALH. True to form the cover was removed, and it was noticed that all the screws were Allen keyed, a mark of quality. It was powered by a four valve arrangement. Ross has several of these amplifiers he is considering to part with. Thank Ross, for bringing it in.

Peter VK7PD brought in a 23cm nineteen element Yagi antenna he had assembled from parts intended for a club antenna workshop. Another RigExpert analyser was quickly produced and connected to the Yagi. The results were pleasing. The said Yagi quickly disappeared into Rosss ute to be used on the next 1296 local “QSO party.” 

Thank you Idris for the update. I must admit Peters battery did have that waxy feel and smell associated with military waterproofing.

UPCOMING EVENTS

TestNet and TechNet – Wednesday 27th April. TestNet/CW course on 3.580MHz from 7pm till 7.30pm….and a TechNet on 3.567MHz from 7.30pm till about 8.30pm. Your host for the evening will again be Nic VK7WW.

DATV Experimenter's Night

https://fb.me/e/1t3WKZEx0

Last Wednesday night Richard VK7ZBX and Justin VK7TW reviewed the ISS SSTV - Women in Space postcards that were uploaded to the ARISS Website.

https://www.spaceflightsoftware.com/ARISS_SSTV/

https://www.youtube.com/watch?v=2nhsK7MFl7Q

Justin and Richard then covered the important aspects of how to do SSTV. Starting with acoustically coupled method which can be as easy as a Smart Phone and Wide band receiver.

This method tends to be susceptible to noise and external influence. On the iPhone you can use the Black Cat Systems application and on the Android platform you can use - SSTV Encoder, Droid SSTV, Robot36 SSTV, etc 

For the electrically coupled method for transceivers like the IC-705 / IC7300 / IC9700 you can use a USB cable to the Computer. For rigs without USB or Ethernet like the FT-847/817 you can use a DigiRig USB for CAT control and Audio Conversion, there is also a SignalRig  for CAT and Audio USB Sound Card.

For the SSTV application on Windoze the most popular is MMSSTV - MixW - SSTV WX Fax, EasyPAL, JBComms. On Linux - QSSTV. On MacOS - MultiScan 3B.

There are many SSTV Frequencies and consult your local band plan - for example 7.033, 7.171, 14.230, 21.340, 28.680, 144.450 MHz. The SSTV Modes are many with the low resolution at the B/W8 and Robot24 upto High Res - P7 - ML320 modes.

There is both Analogue and Digital SSTV - with the digital application including EasyPAL - DRM, JMSK and KG-STV. It is important to get the audio in/out levels correct and most applications have indicators.

We then got Rex Moncur VK7MO into the studio and discuss the VK7/ZL 10GHz contacts article in the latest DUBUS.

We then reviewed the remaining articles in the latest DUBUS magazine.

We then reviewed the New ANZAC Day Contest

https://www.cqcontest.info/anzac-day-contest

And finished with a reminder of the event ahead.

https://www.youtube.com/watch?v=TpYPfshummg

This week we will have a focus on small 160m antennas, more on the VK5JST SWR Power Meter and much more.

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.

Jam-Resistant Waveform for Safer Battlefield Communications to Get First In-Space Test

Onboard an undisclosed host satellite launching in 2024, a Boeing-built prototype processor could become the “first space-based hub” of the militarys Protected Tactical Waveform for jam-resistant battlefield communications, the company says.

Boeings Protected Tactical SATCOM Prototype, or PTS-P, is meant to demonstrate better standoff distance, less latency, “and other mission-enabling capabilities” over existing tactical satellite communications, according to a statement by the company. The prototype has passed its critical design review, and Boeing predicts it will become the “first space-based hub of the U.S. militarys jam-resistant waveform.”

The Space Forces Space Systems Commandin its prior incarnation as the Space and Missile Systems Centerawarded contracts in 2021 for in-space demonstrations to both Boeing and Northrop Grumman under the Protected Tactical SATCOM rapid prototyping program.

“Were making great progress on this pacesetter program,” said Lt. Col. Ryan Rose, the deputy chief of Space Systems Commands Tactical SATCOM Division, in the statement. “Weve asked all industry partners to move fastto build, iterate, demonstrate, and improve performance so we can deploy much faster than we typically would.”

Boeings subsidiary Millennium Space Systems is helping with the rapid prototyping. Part of the prototyping has been to make sure PTS-P is interoperable with other government equipment. The software-implemented Protected Tactical Waveform is expected to run on the militarys Wideband Global SATCOM constellation. Boeing also recently announced the next satellite in that constellation passed its critical design review as well.

The process of placing the PTS-P payload on the host satellite, and the associated testing, will start in 2023.
