good evening guys
I would like to ask for advice on the repair of a pair of drake t-4XC that have
a similar problem.
During transmission in cw, sidetone returns normally, except that in addition
to the manipulation telegraph with a normal note, has a second whistle with the
same frequency note, that should not be there ...
I know there is some problem on the circuit sidetone but I would like an
opinion on who is more experienced than me.
The second t-4XC (that is, what iuse every day as main rig) recently has the
sidetone note it moves a few dozen hertz up and down (only the sidetone
note….not in air) few things; only an attentive ear can find….
For me a bit annoying though, and if possible I would like to fix it.
can somebody help me?
Many Many thanks
