As this item was penned late on Friday, the NTARC Safety Communications crew has already traveled to Santarena Park at Scottsdale, to prepare for Saturdayâ€Ös Equine Endurance Ride. We have established our Ride Base, set up 2 meter and 70cm repeaters for voice and data communications and trialed communications to field check points in readiness. If it is Sunday when you hear this then hopefully we have packed up and are making our way back to Launceston.
As mentioned in one of last monthâ€Ös broadcasts, Andreâ€Ö VK7ZAB noticed a new RF signal about 206MHz. This was later identified to be the test transmissions of the ABCâ€Ös new Digital Audio Broadcasting Plus service for the Launceston area. Phil VK7ZPD soon tracked down an open source software programme called “wello.io” which is capable of decoding the signal. Various versions support differing operating systems and computers. Well Phil has done it again, not sure if he tracked it down or stumbled across it this time, but he located a pile of Sony DAB+ compatible radios that are brand new in boxes. Phil found them at a local recycling depot very near the NTARC club rooms at Rocherlea. They are less than one seventh their current retail price. At $20 you canâ€Öt go wrong with a standalone FM and DAB+ radio that has battery backup and automatically locks to the DAB stream, extracts data and configures time and date on the clock. I know of a dozen that have already been snapped up. So if you are interested in dabbling in digital radio and are a typical amateur, these certainly tick the “cost-effective box”.
Still on the broadcast theme, but now we change from the latest digital radio and head back to early analogue black and white video recording prior to VHS and Beta formats. So over to Andreâ€Ö VK7ZAB for a quick recap on one of the many diverse topics of conversation covered by club members over a drink.
At the last couple of morning teas there has been discussion of domestic Video Tape Recorders that came before the VHS and Beta systems. In particular Stephen, VK7SVG remembers the Philips N1500 system introduced in the early 1970s, being mainly seen in the education institutions before home use. Unlike the rectangular VHS cassettes, Philips used a square cassette, where one reel of tape sits on top of the other.
On the last club morning tea Lionel, VK7ZLB brought in a photo he took in the 1980s of the first broadcast Video Recorder in Adelaide, at the new Channel 7 TV station. It was made by RCA and had been installed in about 1959. This machine was not a free standing trolley style unit but occupied five full height equipment racks.
It was for black and white pictures and used 2 inch wide tape on separate spools, like a large reel to reel audio recorder. The audio and control tracks were recorded along the length of the tape, the same as audio recorders and used 15 inches per second tape speed. The video used a spinning head-wheel that had 4 video heads that swept across the width of tape and was commonly called the “Quad format”. The head-wheel spun at 15,000 RPM and used air bearings. Each head pass only laid down 16 lines of vision – so no paused freeze frames! To curve the tape around the section of the head-wheel a Vacuum guide system was used. Extra station equipment required was a cooling system for the all those thermionic valves, air compressor and a vacuum pump.
These machines were later replaced in the mid-1980s with compact and standalone recorders that used Type C format, a “Helical scan” method using one inch wide tapes. This is the type used in VHS and Beta domestic VCRs. The Helical scan allows full picture pause and variable speed forward and reverse. Note that 2 inch wide tape didnâ€Öt disappear, but lived on for use in the music and post-production studios as the classic 24 track analogue recorder.
Thank you Andreâ€Ö for also contributing to the discussion. From my school days, I remember the Shibaden, a black and white video recorder from the early 1970â€Ös. It was a half inch width tape “reel to reel” unit using two 5 inch tape spools mounted at different heights with a helical scan head located between. They were replaced with the modern colour Philips machines. Video recording systems certainly have come a long way in size and picture quality.
Welcome back Nic VK7WW, to the Hosting reins of Wednesday nightâ€Ös TestNet and TechNet sessions. Once again many thanks to Phil VK7ZPD for stepping in and holding the reins during Nicâ€Ös absence.
Equipment pictures are available on the NTARC Web site under “Blogs” for this broadcast. Now back to the house keeping.

DATV Experimenter's Night
https://fb.me/e/33Wa7PKnF
Our last DATV night demonstrated the diversity of our hobby of amateur radio. We started with Richard VK7ZBX and the Earth-Moon-Earth Contests he has recently been operating in. These included the ARRL and Russian EME Contests. Richard showed a range of screen shots from WSJTX and also some novel pictures through the viewfinder of this rifle scope. He explained the finer points of making contacts using WSJTx during an EME contest and described a number of very impressive European stations.
Justin VK7TW then moved to his Magnetic Loop Tuner designed by Dave Trewren G7IYK. There was a description of the unit including the precision SWR bridge with DDS that disconnects the transceiver and scans the antenna to find out where it is currently tuned and then put in frequency you want to go to and it tunes the loop to that frequency for you - Nice!
You can navigate using the buttons and LCD screen on the unit or use the USB interface on a PC.
Justin then described his challenges with getting this board up and going because of fake chips being sourced from the internet.
This led Justin into a segment on the Fake Chips Scourge that is impacting the electronics industry to the tune of over $7Billion per year.
What is a counterfeit chip - Iâ€Öm glad you asked….
It can be many things including:
unauthorised copies,
not conforming with original manufacturers design, model or performance standard
not produced by the original manufacturer
off specification - used, defective or misleadingly labeled as new or
incorrectly marked or with wrong documentation.
We went into some examples of fake chips causing problems and even death of an Air Force Pilot.
There are some designs for counterfeit measures being used like unique ID and unique Physical Unclonable Feature (PUF) and blockchain also being considered.
Thanks to Asianometry for this information.

We finished with a reminder about the DATV QSO Party last Friday night and the up and coming Sept Presentation Night on the 6th Sept from 7:30pm with Ben VK7BEN about Cyber Threats.
The video of the night is available at the REAST YouTube DATV playlist and the link is on the email version of this broadcast.
https://www.youtube.com/watch?v=4aMKqEFbnx0
This week will see another DATV Experimenterâ€Ös night with some interesting experimentation and equipment reviews.
We stream the nights on the REAST YouTube channel.

https://www.reast.asn.au/special-interest-groups/amateur-tv/
https://www.youtube.com/c/ReastHobart/
We also go out on RF - DVB-T 7MHz Standard Definition on 445.5MHz. 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.
