Vintage Transmitter de W2GUM

A "HOLLOW STATE" rig.
A "QRP" [low pwr] one-tube, free-running oscillator transmitter.
This method/style of building radios is called "breadboarding" because that literally was what was often used. Atlanticon Hamfest [radio exposition/flea market] Note the one-turn loop to a #47 bulb tuning aid. It also has DSP - Da Same Principle. It don't get prettier than this my fellow hams. "GUM" himself was displaying it! ...And I did not dare to ask if it was for sale for fear that he may have either justifiably slugged me or just politely smilied. You can't be sure when good stuff like this is displayed. Casio 3000EX florescent lighting.
