It's probably a bad ground connection at the antenna. The coax shield needs to have a good ground (ground plane) or else you'll have RF feedback through the mic cable due to excessive RF traveling back down the outside of the coax and making the radio "hot".

Every tech. knows and every Connex owner Knows that once a Connex has been peaked and tuned and also had any mods done to it that the stock microphone that comes with it will not work as it should and then you will have bad feed back!! The best solution for this is buy a good Noise canceling microphone!! Such as an RK-56 or an Astatic 636-L Noice canceling microphone!! This usually will correct most of tghe feedback if not all of it!! And it will also let you keep most of your Mic gain turned uo too.

Bad RX/TX Transistor? I don't have a diagram for the 4600. Sorry!

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
SOURCE: I have a connex 4600 turbo very good radio!! But
check for any loose power connections.. ground connections.. loose coax.. also make sure vehicle is on so not to drain battery down when TXing. if it was off it may have dropped battery voltage down lower than it should... and turned off.. RX doesn't use hardly any ampres..
