Elecrafters,
a little while ago i had an issue with loss of rf-power.
I thought i had found the problem. I hadn't.
Symptom now:
Power out only about 3 Watts.
I removed the 100W-PA, changed the Menue to 'not inst'.
With TUN PWR set to 12W i can achieve about 2.5W .
Only 1 of the 3 Transistors on the low-Power PA gets warm during (short)
transmissions with the bottom cover removed.
There are 2 RD15HVF1 and 1 RD06HHF1. How can i check if a transistor is
defective?
Any help welcome.
I think the 100W PA is ok. Well , i hope .
