Ok I looked up TR4 and TR11 and found them to be 2sc945 NPN type transistors. it didn't help much at all!!Ĭould someone please help me diagnose and doctor this nice little unit up?Īnd if I can get the RX side fixed I would be interested in knowing how to install variable power in this radio as well! I have already gone through the schematics I found on another site and turned the AM RX gain variable resistor up. The bad: It is pretty week on the RX side of things! I have another older comparitive base here.an 86xlr and there is a 3 to 5 db difference in the 'ear' on these radios! The 86 is stock so I don't think there should be that kind of difference with the same antenna, coax, meter, etc.!! AM, USB, and LSB all sound really good on another radio and shows good modulation on a mod meter! the good: it seems to do really well on TX. So here is what I have that I need help with. I am a little new to this troubleshooting side of the radio biz!! I have a little basic knowlege of how circuits work and how to peak and tune and all that and I follow directions well!!
