Seems that I read some time ago about some of the earlier model CB radios having problems. I have the opportunity to purchase a CCA-1010 model built in 2004. Anyone remember what those issues were that the newer CCA-1020 fixed?
The early CBs had a problem with the squelch adjustment. If I remember correctly, the range of adjustment was too narrow, so the radio received everything or nothing. Early CBs were replaced or repaired. The improved radios were identified by a blue dot printed near the serial number on the box.
A Service Bulletin was issued for the CBs.
