Kenwood Trio TR-1200 50MHz 1W AM/FM Portable transceiver (With a transceive VFO) Made with transitors. I had to purchase three sets till I finally got a good luck to get a complete one looks brandnew being kept in a original carton box for 30 some years.
This series of radio were the best line and dream in those days, and I used to see them visting old-timer's shack in local. I was just impressed and excited looking at him working Europes after another on AM with a 21MHz dipole antenna put up in the garden.
It was very common that strong stations on 50MHz were also using TX88A. Those who put modification on final, changing final tube to 6146B, supplying extra electric power from homebrew external powersupply, using external modulator putting out a "big power" of 50W, were Court nobles. A viblation noise from the modulation transformer of TX-88A for its AM modulation work used to freak me out.
