KX1 STILL NO TX! Help Please.
Still can't work out where my TX fault is, I have a tiny amount of RF at the antenna out.
A Few measurements made using an RF probe and dc voltmeter
At T1 Pin1 5 volts
Pin2 0 volts
Pin3 0 volts
Pin4 1.9 volts
Q6 Base 1.9 volts
Collector 0 volts
Emitter 1.8 volts
DC voltages seem about right, tried lots of stuff remove rewind T1 replaced q4 q5 q6.
Anyone who can help guide me where to look with the RF probe to narrow the problem down a bit,
I don't seem to have enough knowledge to move forward.
Thanks Mike G0HIO
