I guess it must be this one:

The beautiful photos in the previous post show the French Cold War spy radio set TR-TG-2A. See:

Morse Code / Morse Mania

Using a great phone app called Morse Mania ...

Puzzled to find that this great software hasn't been mentioned in the forum until today. Here is the developer's site:

https://www.blackcatsystems.com/index.html

I started using Morse Mania on my desktop Mac more than 20 years ago:

The desktop/laptop version is Mac only, but for cellphones they have made it for both dominant systems:

Additional information in the Wikipedia article about the British Clansman military radio system:

https://en.wikipedia.org/wiki/Clansman_(military_radio)#UK/PRC_316


QuoteClansman HF radio sets
UK/PRC 316
A late introduction to the Larkspur range, its original designation was A16 Lightweight HF Radio Station. Deployed in tropical or high temperature climates, it was powered by either a standard 12V battery that connected directly to the set or if issued, a Leclanche Battery that connected directly to the set. It was compatible with most D10 or R4 copper stranded antenna systems that were fielded at that time, examples being the Shirley, Jamaica, Half Jamaica and Yagi.

Despite not being of the Clansman family, its late introduction to service coupled with its Clansman equivalent, the PRC/RT320 not being ready, meant the PRC 316 survived for just over five years after Clansman was introduced. Once the PRC/RT320 was completed and fully fielded, the PRC 316 was rapidly withdrawn. Another reason cited for its retention was that it was relatively easy to operate and was inter-operable with the other HF Radios in the Clansman family.

This radio has been mentioned once before in this forum, with reference to the same PDF:

when I was working in Kuching, Sarawak, Malaysia , I picked-up a locally published book; "SAS In Malaya" and, like you said, Gil - the jungle warfare people did amazing things.  They Malay campaign drove the development of a far better radio;  the PRC-316 and STRONG reliance on NVIS.  Here is a link to an interesting article from your mates at VMARS, describing it's use.

I wanted you to see the beauty of this one. And in that PDF you can see the PRC 316 and accessories.

I wonder if you can buy this radio somewhere?

QuoteThe UK PRC 316 / A-16
by John Teague, G3GTJ

INTRODUCTION

This paper describes the PRC 316 and is an expanded version of an earlier contribution to the Centre for the History of Defence Electronics (CHiDE) colloquium on Military Communications, held in September 1999.

The radio was designed and developed for the British Army in the mid-sixties by the Signals Research & Development Establishment (SRDE) at Christchurch. Designated X3145 in the experimental phase it became "Station Radio A-16"; later it was given the Clansman style designation of "UK/PRC 316", which is how it was generally known in service.

To quote from the November 1968 edition of the User Handbook: "The lightweight HF patrol radio PRC 316 is a compact, simple to operate transmitter-receiver developed primarily for use at the halt. It provides 45 crystal controlled communication channels in the band 2 - 7MHz . . . . (It) is intended to operate at ranges up to about 800 km using CW."

When will QSX be available?
We don't have an exact date, it depends how long it takes to finish all the above features and manufacture it etc. *Hopefully* something like November 2018, but this could change. Any updates will be published on this page.

Update 25-Jan-2019:
Development continues, progress is being made but there are a lot of details to take care of. Still no update on projected completion dates yet.

Update 05-Nov-2018:
We have some delays due to poor health, see https://groups.io/g/QRPLabs/message/27851 - recovering nicely now so will make more progress soon and update on this page.


Regarding the last link in there -- I wish Hans Summers the very best health recovery!

If the QSX kit wasn't coming out, presumably soon, I might have bought one already.


The thread about that one: http://radiopreppers.com/index.php?topic=1507.0
[... looks interesting - QRPlabs QSX all mode, all HF bands, 10 watts - $150 !!!!]

This $350 transceiver from Odessa in Ukraine looks very interesting and affordable to me.

• "This is a small-size 10 band short-wave QRP transceiver."
• "The transceiver has small dimensions of 100x103x30 mm. and a light weight of 430 grams. It will suit both for work on the field trip, on nature, at the dacha .... So for everyday work, at home."
[...]
• "Power supply voltage: 9-14.8V (Rated supply voltage 13.8V)".
• "Consumed current in the "RX" receiving mode and 25% loudness: ~ 120mA. At 100% loudness: up to  ~ 250mA."

-- They say nothing about batteries -- so what would be an optimal battery taking this set for hiking in the mountains?

Also, any comment, such as user experience, will be valuable to me.

An interesting thread has shown up on the SKCC Google Groups mail list.


That Google group is history by now (my bolding):

Quote from: https://groups.io/g/skccThe Straight Key Century Club is the fastest growing group of  straight key Morse code operators and enthusiasts in the world. Organized in January 2006 the club has thousands of members around the globe. This Groups.io group is a meeting place for general discussion by SKCC members of all topics related to manually keyed Morse code, including mechanical bugs and sideswipers. It is the successor to the Yahoo SKCC group as of September 2017.
