Elmar V?ller
 

Hello,
this famous trx produce annoying chrash during rx/tx switching.
I combined a simple agc curcuit together with muting system to get
rid of any cracks.
Is anyone interested ?

When you say solder 1n4148 t0 +12v not RX, which one are we talking about?

from junction r111/r113 solder a 1n4148 diode direct to the 12volt rail
(LM368 is now alltime connected with 12volt)
