one tube xtal tx
 

Hello

I am looking for schematics and any other help in making one tube CW QRP
transmitter for 80m band, BATTERY operated. I think about 3s4t or 1t4t
(DL96, df96).
What is minimal anode voltage (typical is 67,5v) which I can use with
this lamp?

You'll probably get better answers, but...

I once had an old MW radio that used tubes of this kind. It worked fine
with only 18V on the anodes. (two 9V batteries in series)

Many thanks to Doug and Richard.
Of course I will take with pleasure any other help or informations.
After my success with cubic incher, pixie and aquarius i want to try (or
rather return) to tubes. My first transmitter was ECL82 ;-)

Doing an altavista search on "glowbug" will turn up at least one battery
powered transmitter project, and lots of fun tube stuff.

It was the KEYword that I was looking for ;-)
Thank You

19 tube should be fun, I'd go with around 67 or greater for the plate.
