2970 dx carrier balance


Moleculo..didnt realy see what i was hunting for there..whats going on is when i turn the mic gain on the radio all the way off and key the mic im showing about a half watt of carrier whilst in ssb mode..from what i understand there should be 0 watts on a deadkey on ssb....
 
You need to start with the PLL/Oscillator Alignment procedure. That will likely solve it. If it doensn't, you probalby have a diode going bad or one with a bad solder joint around the balanced modulator. I haven't personally dealt with this problem on that radio, but this is a place to start.
 
Yes, and you must do each step in the order listed. Should solve 90% of any misguided attempts from prior tune-ups.

    Hello gentlemen and Ladies. I have the dreaded RCI-2990 receive issue where my radio gets distorted when people get close to my location. I found the C90 Capacitor, but I can not for the life of me find the C89 capacitor. Can or does anyone have a picture of the exact location of C89 ? Thank you in advance, Wes
