Sidetone etc. - DX-60 monitor circuit from Harry SM0VPO

[Fred Finster]

Harry's Homebrew Homepage   SM0vpo Has a Code Practice/ Transmission Monitor
Here is a little novelty circuit that I found in some time ago, dug out of
the archives after an E-mail request. The circuit was given to me by the
late G8ABZ in about
1967 as a circuit that will oscillate first-time every-time. I have added a
diode detector so that it will generate a sound when a transmitter is keyed.
