Bill,
Voltage at the drain of Q24 will only appear during transmit, TUNE or when
you have selected CAL FCTR in the menu. Try it in one of these states and
see if you have a signal at TP2 - the expected level is in the 0.25 to 0.70
volts RMS range (if measuring with an RF probe) - if you are measu
Hi Group,
I have been struggling for a month to figure why I have no BFO at TP2. Also,
Q24 voltages measure zero all around. The gate has a very small (10 mV peak)
distorted version of the nice sine wave on U11's nice 1V peak sinewave.
I have traced all the way back to Control Board U8 pin 2
