View Full Version : 142 GTL No Transmit on am

09-28-2013, 09:52 PM
I picked up a 142 GTL on Craigslist and it has transmit on SSB but no carrier on am. frequency counter showing slightly off frequency on key up and when I talk into mike, I am using a D104M6B, It swings from nothing to about 6 watts. Unit has two toggles on back obvious channel conversion done. Receive is good. I replaced driver and final did no good. The voltage on the driver and final flange is 13.05 on am and 13,78 on ssb when on receive, driver drops to negative reading on transmit and final goes down to .20 what would cause the over voltage and drop? any help would be appreciated. Thank you in advance. JIM

Check the voltage regulator
