Folks,
A friend of mine gave me his President Jackson to look at because of no RX or TX. The Jackson is a 5 band AM/FM/SSB transceiver.
This radio has special meaning to him, as was his late Father's.
Anyway, radio lights up and works good on PA mode, but no TX or RX. Last time the radio had trouble (1997?) it was for cold joints in the VCO area. Checked for same and 'resoldered' everything in the area.... nothing.
I also replaced the oscillator crystal..... nothing.
Should've checked the caps and/or transmit/rx transistor (if so equipped), as the RX light works on RX, but the TX light does NOT come on when I key the mic in any mode.
The service manual on CB tricks is pretty 'light' for this radio... dunno WHERE to start.
Any suggestions before I start swapping components to find the fault? (I'd really like to help him out w/this.)
Thanks
