I am in the market to replace my Uniden 396T. I listen mostly to AACo and USNA, however I do travel around the region, up to Baltimore City, and west to Montgomery County. The P25 decoding with the 396T (hence the audio performance) is not the best, so I'm looking for recommendations between the various Uniden and GRE radios. Another question: is there any perceptible difference in receive performance between the current handhelds and mobiles?
