I'm using a different Cobra 29 with it and I have the carrier set at 1 watt...
I may have figured out what potentially ruined the driver and/or final. Tonight I was using a brand new 29 from my pickup as a reference radio. I checked the receive and transmit voltages on IC3, TR16, TR15, and TR14. Everything was pretty much a match between the two except for the...
If I unsolder them there is no continuity from the modulation to the amplification. I physically cut the trace in the circuit board for my Mauldulator install. That circuit had been working for a few days before this happened. I checked all around those wires for shorts and proper continuity...
Hey there, first post, long time random looker...
I have a circa 2015 Cobra 29 that has lost transmit, presumably because of me. I've got a Swiss cheese, generalized knowledge of electronics, but not a great understanding of circuit tracing and fault finding. So here we are with my back...
