I am troubleshooting why I can't hear CB input but can transmit from my headset. When I bought the 2000SE in Dec '12, it had the same cb antenna as the am/fm radio antenna. There was no black plastic in middle of cb antenna. Could this style be correct for 2000? The am/fm ant looks exactly like the CB ant.. Do I have the wrong cb ant? Does anyone else have exact matching antennas? thx Again,,,the problem is that I can barely hear the squelch or incoming signal.
