OK, I have two cobra 29 LTD‘s . One is from Taiwan and the other is from the Philippines. My Taiwan radio when receiving, sits at zero. The Philippines model sits at about three. When people talk, I get the same signal. The problem here is that, people who give me about 3 pounds I have a hard time hearing them because I’m getting 3 pounds of static where as the other radio is quiet and sits at 0 pounds . Does the radio need an alignment for the meter to sit at zero even though people give me the same signals on both radios?
