Picked up another 2990 (why?, I don't know) with problems. Here is what is wrong.

Low RX on ssb, tx is perfect
No AM RX audio, signals are coming in perfect. TX is Perfect
Scratchy noise, not whooshing on all modes...mostly on AM though
"ON AIR" led is always lit on RX, TX is turns off

I have replaced the audio chip with a known working, same issues. Voltages on IC6 and IC15 are good. All connections check on board are good. Radio looks all stock, but noticed SWR board is removed? Not sure if all Saturn Turbos and 2990's had this removed...but just to note.

Help is appreciated!
Thanks

    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
