Re: SoftRock RXTXv6.2 40m _30m PTT Stuck on
- I finally had some time last night to look more at the Stuck PTT
problem last night. I pulled resistor R37 out and the voltage at the
base of Q10 went up and the collector Voltage (s12v) dropped to 0. I
replaced the FETS Q7 and Q8, but with R37 back in the base of Q10 was
12.1 again and s12v was back up to 12.69v. I pulled R38 and C24 to
isolate the circuit but s12v stayed up. I suspected C61 and pulled it
but at 1:30 this morning I was having difficulty reading the meter
and quit, so I don't know the results yet. I've verified all the
component values and checked for any shorts or bad solder joints
under the magnifier.
Am I on the right track?
Anyone have any other Ideas what could be pulling down the base of
