Hi all
Thanks to Martin and Dave for the advice so far.
One thing is puzzling me with the radio and that is this, When I switch
to SSB (upper or lower) the radio transmits what ever power level has
been set with the drive control, I have always thought that it only
transmitted with audio is applied via the mic, or have I got it wrong!.
I am wondering if I have additional problems.
The voltage levels on the 4558 appear to be correct, I have changed it
anyway but the voltage on U1 pin 1 is only <3v not what is written, all
other pin voltages are correct.
So more head scratching today ( I must be careful of getting splinters
ha ha).
stay well and happy
