how would I go about applying a ring modulator to my cobra 2000? Guessing tp7 and tp8 have something to do with it.. what other things are needed? Radio is already direct injected just curious what the gains are? Thanks a lot any input would be great

Never heard of it. Where did you read about it or see it. Some additional context as to what you're after would be helpful.

discrete diode modulators are a bit archaic but so am I .
If you want to play with dual sideband suppressed carrier that's fine.
It's actually a step backwards in most cases.

    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

    Wes, it's better if you start a thread on the main forum, more people are going to see your question.
  • @ heartbreaker3473:
    Okay, sorry, will put in a forum
  • @ heartbreaker3473:
    I put it in the general disscution help area and started a new thread. Thank you for letting me know.
