Re: BAD SWITCH ???
There seem to be multiple causes of an initial RF pulse on PTT activation.toggle quoted messageShow quoted text
1) AF caused by PTT switch operation
2) Voltage changes as circuits are powered up...or down
3) momentary reflections toward balanced modulator, caused by
bi-directional IF amplifiers changing direction.
In past messages several persons have indicated they have partial fixes
for some of these problems. Those individuals may point you toward
their posts, or you could search the older messages for this subject.
