- Wed 29-Mar-2017 – 5th Wed: HF Show & Tell
HF Show & Tell with the usual voting for the best piece.
We saw homebrew, unusual commercial radios; QRP and portable radios; Old radios with some valves, a transformerless linear amplifier, etc.
And the winner was Russell with his ??? marine HF … and obviously the story that came with it!
Some people have asked me about the Transworld TW100 transceiver that I brought up for “HF show and Tell” on Wednesday night.
These are a synthesised HF transceiver of 1980s vintage, offers LSB/USB/AM/CW/Data transceiver rated at a very conservative 125 watts from 1.6-30mhz with scanning and a possible 100 programmable channels. They were used in military and commercial operation (often in combination with the Transworld T1000 (a 1kW solid state amplifier) and were made in California. The Company is now Datron: http://www.dtwc.com/
As a really, really strange coincidence the first contact I ever had on my TW100 was on 40m with VK2BLC in Dubbo. And he was also running one of these Transworlds!! Here is his webpage, and you can see (one of) his TW100 in the rack next to his operating position: https://www.qrz.com/db/VK2BLC
I have looked further down his webpage, and see that he must be a “special” type of ham, as he has another TW100 and T1000 combination in his Kombi van. (Although he says that the amplifier only runs 400W to keep within the amateur licencing regulations). That is not too extreme I hear you say – BUT he also tows a trailer with a generator to supply the necessary power while he operates HF mobile (surely he means stationary NOT mobile????)!
