Batboard

I have a CDM 1550 LS that I am using on conventional mode. I have programmed it and have two issues that I can not seem to resolve.

When the radio is on talk around mode, the transmitter makes an awful screeching sound on the receiving radio.
I had the same problem at first on regular repeater mode, but when I turned the transmit power down to 25 watts from 40 it stopped.

The other problem is receiver squelch, I set the reverse burst to " non- standard", as we are using a Kenwood TKR-8400 system, and set the muting to "And/Or" but I still get a large squelch crash at the end of recieving.

Is there an internal squelch gate adjustment inside this radio? If so where, and how do you adjust it??

Thanks

the reverse burst is for transmit, not recieve so that wouldn't affect your screeching sound. the and/or setting is for more than 1 option on recieve like quick call so it will unmute for your dpl/tpl and/or qcII. put a meter on your antennae and make shure it isn't grounding out and see how much is being rejected back to the radio.
