I have a pro-164 and I have some trouble programming some edacs and ltr for the metro albuquerque area. I put in the frequencies listed in the database for new mexico exactly, then double checked them, but still trouble. Motorola works good though. I'm pleased that my 164 has the uhf airband. Years ago I had a 300 channel scanner with uhf airband, but it got messed up after I unknowingly recharged nonrechargable batteries in it.
