Using my BCD436HP in Georgetown I have MARCS sites for Brown/Clairmont/Adams and the analog channels for FD/PD. Most of what I hear is MARCS not much on the older analog freqs. The paging is working with tones very clear. I am also catching the airport traffic from approaching small airplanes. I’d say in my opinion the BCD436HP does better than my PSR-500 in this area. Last trip was 2 years ago. Just making a local observation. Out here deer hunting for a few.
