I have the Dynamic squelch control on this radio and I know it was talked about before. But does anybody know if it can be adjusted. Stock it squelches way to much, it may be useful if I could adjust it a little.
 

I can read thru the 32 page manual but I am not a teck and dont have all the equipment. I was hopeing that there was a simple adjustment or a quick fix to adjust. As it is now it is an on off switch tha kills the receive. I cant be the first to want to adjust this! Others say it makes a good switch for talk back.
 
Here's a review from Amazon and no,I don't know how to adjust one yet
" Could Not Hear Anybody - Squelch Defective
By Lux Camper - June 9, 2010
Purchased the radio new, and installed in the same place my old radio was mounted.
My first impression was: "Wow is this thing quiet, compared to my old radio."
Well, that is because the squelch circuit was defective, and a person had to be within 100 ft of my car for me to hear them. Took it to my local CB repair shop, just to make sure it was the radio, before sending it back, and it was. The repair shop said this is not the first time they had seen this problem. Did not have anything to do with the Dynamic Squelch.
Sent the radio back and received a refund.
Never did get to run it through its paces to compare perfomance. Now I'm a bit gun-shy to try a Uniden 68 again.

What I did like, was the good sound of the speaker, and the microphone. The front panel lights and meter were not too bright at night. Overall, had the radio worked, I would have given it a high rating.

Just the luck of the draw, I received a bad one."
 
Thanks! Mine isn't defective but not useable at the present setting. It would be nice to be able to adjust inside the radio. Be able to turn it on or off at the setting I want?
Thanks again

    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
