Good morning everyone. I finally got all the mods on my radio straighten out. I've done every thing i could find down to the ekl final and trim pot volting the gate. I have it set up for 3.5 v on tx and its swinging pretty good. The variable power brings the dead key from 0 to almost 10 watts for use of an amp.

I changed the 1k pot from rf gain to 5k thinking i could decrease sensitivity on the control but I'm wondering if that is throwing any thing off i might not realize. This is the tip 120 transistor mod. 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
