I have a Connex 4600 Turbo mounted in the headliner of a W900L Kenworth using Wilson 2000 twin antennas and a RK56 mic. When trying to use the "talk-back" feature all I hear is constant "sqealing". This radio was tuned & peeked when bought new 1 yr ago. Any solution?

Had the same problem. Try backing off the RF gain just a bit (about 4 o'clock ) and set mic gain 2 o'clock or lower ...that worked for mine ..it is still plenty loud
Strange. You shouldn't have a squealing problem with an RK56 noise canceling mic.
Unfortunately there is no way to change the volume of the talkback. Its too loud. The only solution is to turn the mic gain down.
The only reason you need to have talkback on is to check your audio. Make sure the echo is good and what not. After that you really don't need it on. So turn down the mic gain, then check the echo, then turn off the Talkback and turn the gain back up.
The squeal is feedback from the talkback being to loud and being heard by the mic. So the only way to solve it is to lower the volume of the talkback, (Which is not possible in this radio) lowering the mic gain(which lowers your audio level) or turning it off.
