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
