Vintage tube QRP rigs
ve3lyx:
At a local antique store I picked up a 1943 ARRL handbook. There is a breadboard transmitter in the transmitter chapter that looked interesting. I checked my junk box only to discover I had everything to build it except the breadboard. So I am underway. It is a crystal controlled 6v6or 6l6 rig Cw only. Low power tube rigs are for me a great source of fun. I am building it for 80M although the article has specs for 160M and 40M ops as well.

It is up and running. Very stable with a nice note. I tried it both with a 6v6 and a 6l6. Despite the lower voltage supply I have it on (246v key down) which should favour the 6v6 the 6l6 still performs noticeably better. Am testing on 3561KHZ (3561 crystal) when the band is open. CW only.
