Nice idea - I looked at this too - but it is CW only, I think.

If I could build it, then Iād have a go. Just need the time to do it
Yes, CW only, but I think a small mod and a simple AF amp and you could apply grid modulation at the cost of reducing output. I havenāt played with a regenerative detector for years, the idea is getting quite attractive!
Temptingā¦ I have just found 2x NOS ECL82 in their boxes and a possibly NOS ECL82 unboxed in the component stores.
