Know this is a bit off topic but does anyone know of plans/build it articles using the 1625 tube for a simple one tube crystal controlled low power cw ...
Hi Lynn - I see you like a variety of Yahoo groups. I can't answer your question on Tx circuits but thought you'd enjoy these 1625 based recievers. ...
Lynn, why don't you just find a single tube transmitter circuit and substitute a 1625 in it? If you stay with a B+ of 300 to 400 volts, you will barely be...
Chris Thanks for the reply. I have a regen in the works using the 1625. I like the looks of it. Now want to build a cw qrp transmitter using the same tube....
Shouldn't be a problem. Look up any of the vintage 1950's Novice transmitters. Cathode keying, crystal oscillator, Pi tank output. Only parameters that might...
Hi, Folks: Happy Fourth Anniversary to the List! The first message was posted 17 November 2004, from whence this list has grown to over 600. Glad to see...

Jeff, Paul and others. The two best web sites for finding construction articles for simple tube transmitters, will be found at these two places: You will also...
Hi, The noise bypass capacitor that goes from the wiper to ground. There seems to be a lot of variations. In Rockey's regen radio book he says (1.0)mfd...
Hi Jennifer, My 6J7-6C5 Jones autodyne works well with a prescribed 0.25 mfd. I have seen other authors use up to 5.0 mfd for the screen pot. I find either the...
... I'm with Bob. I rarely if ever find a need for anything larger than 0.25 mf. The way I calculate it is that if the pot is THAT noisy then it needs to be...
Hi, Thanks for the replys. So .25-.5 mfd seems popular. The subject of screen was mentioned. What if it's a triode. Any different ?. Or is it a case of it's...
... In the old days the main purpose of the cap was to mitigate the noise from a scratchy pot. I guess it still is but I haven't encountered recommendations...
Alan, Which Kitchin regen are you looking for? Far Circuits sells at least two different Kitchin regen boards and one of his superregens that I know of. I have...
... I was just thinking of building one myself as part of a portable transmitter/ receiver for a winter project. Far Circuits has the Boards and there aren't...

John Thanks for the reply, appreciate it. I've got a few homebrew tube regens, but have neglected the solid state versions. I'll take the lot, like to play...
... [deletions] ... Keeping in mind that the purpose of this cap is only to shunt regen-control noise to ground, I'd use as small a value as possible for this...
