Good question and answers here I did the same as don suggested up till recently. I have a Heathkit TX1. I had no receiver until recently when I got the RX1 to go with it. bit of a crappy reciever but its still a fun to do the nostalgia thing. The TX1 will crank out a whole lot more power on AM and CW than the K3 and it warms the shack in the winter. Its not all DX and contests sometimes its fun to get out the old and tinker. next up is 1930 era two tube push pull UX-245 40m transmitter now were talking chirp!.

I've built it and it works FB.


As far as why one would want to do this: It's just downright "fun" to build a homebrew tube rig, for QRP or otherwise, and to restore a vintage transmitter. If we already have a good, modern transceiver in the shack, then half the problem is solved.


I've had much fun with my Xtal controlled 6C4-5763 rig, chirps and all....

Eric,

Although I am not certain why you would want to do that, it can be done - Elecraft gear offers seamless transceive operation all by itself, so I do not understand the fascination with an external tube type transmitter. OTOH, if you really want to do that --
