Well I don't regret, but the TEN-TEC ARGOSY MODEL 525-D was the one I loved very much
and one that I kept 15 years of very good service and I had really lot of fun with it doint thousands of QSO's
It was a very simple, construction and to operate as well.
The Argosy was only SSB/CW transceiver, with 5 watts/50 watts, or anywhere in between, as low as one watt out.
The only reason I sold it, was at the time, to have a new transceiver with more features such as the new WARC bands, the addition of 6 meters and also all modes, which are a must.
But sometimes it is a question of finance, and new technology.
Finally new technologies, yes, but I'm still doing the same good CW day after day.-
