Friday coffee morning once again started with Ros arriving early, turning on the urn and making everything “ship shapeö and bringing her extra special treat of magnificent lemon slice. Our members were also treated to the Fire Service conducting a training session behind the football club. It involved a helicopter repeatedly coming in and hovering about a metre above ground. One group of fire fighter would disembark and the next group would board. The helicopter would then fly off on a fifteen minute return trip and repeat the same procedure again. This continued for a couple of hours and provided visual entertainment for many. As to be expected of amateurs, out came the smart phones as they fired up their flight tracking software. This in turn prompted a discussion of amateur oriented phone apps, with Peter VK7KPC going through some of his collection, covering the usual Slow Scan TV, Morse code, and RTTY with their various water fall displays. One that will certainly need re-visiting was “Loud Bangö. According to the manufacturer “F-Droidö it is the “First WSPR client for Android that can not only transmit beacon signals using the phone’s audio output, but also receive and decode beacons using the phone’s audio inputö with many other features. All in all a great morning.
Last Wednesday was TechNet night, but Nic VK7WW had a prior commitment and was unable to be our host for the night. However, once again he left yet another incarnation of the ‘QRP Nic beacon’, this time in the 160 Metre band on 1.843 MHz. This version also came with a massive power increase from 100 to 200 mW, but still based on a single transistor design. Apart from local reception it was copied in the Northern Suburbs of Melbourne by Greg VK3CN on an indoor frame antenna. The recording showed that the Morse code was indeed very readable above the abundant local noise. The next night Nic received a reception reports from Central Victoria, coming in at a very respectable 599, from Luke VK3HJ. Thanks once again Nic.
When you hear this, the NTARC Safety Communications crew will be recovering after helping Dave VK7DC and his crew at the Kentish Equine Endurance event held on Saturday. Hopefully all went well and some may even make it to Ross today.

DATV Experimenter's Night
It was great to see Harry VK7HXT and Ron Cullen beavering away with soldering iron and laptop. Harry working on his broadcast patch box and Ron working on internet controlled mains switches.
Ron demonstrated his four remotely controlled devices after the DATV presentation.
In the DATV studio we started the night with Larry VK7WLH and his very impressive little credit card sized Belka-DX SDR Rx. This is a 1.5-31 MHz fully functioning receiver has a large LiPo battery and antenna. It has an option for a speaker and slightly smaller battery. Normally it is run with headphones, it also has an I/Q output as well. Thanks Larry.

Justin VK7TW then showed his home brewed Handi-finder Direction Finding Antenna with two out of phase loops and a switching circuit that switched between each loop at an audio frequency effectively causing phase modulation at audio frequencies with a stronger tone from the loop pointed toward the signal source.
https://www.handi-finder.com/
Justin and Larry then demonstrated the Handi-Finder antenna using the Microfox from last week.

We then showed the Calibration Certificates for the Pyranometer he showed a few weeks ago. Kim VK7KB was able to pull in a favour and source the certificates. We were able to confirm that the Pyranometer came from the Hydro one.
Justin then took the audience through how to manually determine the matching network using a paper Smith Chart using the technique from Alan Wolke W2AEW.

Impedance chart - https://www.acs.psu.edu/drussell/Demos/SWR/SmithChart.pdf

Justin then did the same exercise using the SimSmith application to demonstrate arrive at similar results and Justin show the physical matching network using the results.

We finished with reminders of future events.
https://www.youtube.com/watch?v=hjobZAur8uU
This week we continue our look at what you can use Smith Charts for, the results from the physical matching network, the latest AR Magaazine, RF interference created by Class D audio amplifiers thanks to VK7JUF 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.

Russian soldiers uses Chinese portable radios during Kremlin’s invasion of Ukraine
Dylan Malyasov writes on the Defence Blog website that
The Russian military has used civilian mobile phones and radios for their communications, including Chinese-made civilian handheld radio, during the ongoing Kremlin’s invasion of Ukraine.
According to the Defense Express magazine, the Russian military is using the BaoFeng UV-82HP radios for communication within the frontline units currently stationed in Ukraine.
The Ukrainian military manages to seize Russian combat vehicles and equipment, among which were frequent Chinese radio stations and documents with call signs and radio frequencies for communication in a highly congested and dynamic operating environment.
The Royal United Services Institute (RUSI) noted that the BaoFeng UV-82HP radio uses V/UHF wavebands and lacks military-grade encryption. Why it was reportedly in the possession of Russian troops is unknown. However, this triggered immediate speculation on the health and performance of Russian Armed Forces radio communications.
RUSI says that evidence of Russian communications in Ukraine indicates that the modernization of the Russian Armed Forces has been troubled, causing operational and tactical challenges.
“Open-source intelligence and Ukrainian reports suggest that radio communications across the Russian forces are poor, leading to makeshift solutions including the use of unencrypted high frequency (HF) radio for long-range communications and mobile phones to communicate,ö said RUSI’s report.
At the same time, Russian soldiers themselves note that the Ukrainian army uses the latest tactical radios manufactured by Harris, Motorola and Aselsan.
For pictures and the full story take a look at the website address on the email edition of this broadcast.

Half of world's neon output for chips halted by two leading suppliers based in Ukraine.
Alexandra Alper in IT News writes…
Ukraine's two leading suppliers of neon, which produce about half the world's supply of the key ingredient for making chips, have halted their operations as Moscow has sharpened its attack on the country, threatening to raise prices and aggravate the semiconductor shortage.
Some 45-54 percent of the world's semiconductor grade neon, critical for the lasers used to make chips, comes from two Ukrainian companies, Ingas and Cryoin, according to Reuters calculations based on figures from the companies and market research firm Techcet.
Global neon consumption for chip production reached about 540 metric tons last year, Techcet estimates.
Both firms have shuttered their operations, according to company representatives contacted by Reuters, as Russian troops have escalated their attacks on cities throughout Ukraine, killing civilians and destroying key infrastructure.
The stoppage casts a cloud over the worldwide output of chips, already in short supply after the coronavirus pandemic drove up demand for cell phones, laptops and new cars, forcing some firms to scale back production.
Before the invasion, Ingas produced 15,000 to 20,000 cubic meters of neon per month for customers in Taiwan, Korea, China, the United States and Germany, with about 75 percent going to the chip industry, Nikolay Avdzhy, the company's chief commercial officer, said in an email to Reuters.
Cryoin, which produced roughly 10,000 to 15,000 cubic meters of neon per month, and is located in Odessa, halted operations on February 24 when the attacks began to keep employees safe, according to business development director Larissa Bondarenko.
Ukrainian neon is a byproduct of Russian steel manufacturing. The gas, which is also used in laser eye surgery, is produced in China as well, but Chinese prices are rising steadily.
Neon prices rose 600 percent in the run-up to Russia's 2014 annexation of the Crimean peninsula from Ukraine, according to the US International Trade Commission.
