I've found the HP1 is deaf. Receive isn't as hot as I believe it should be.
I'm curious if anyone can comment on the new Unidens receive performance compared to the HP1.
Side by side test with my BCD996XT & BCD536HP shows that the 536 is more sensitive in the aircraft, VHF-HI and UHF bands. Receives distant stations more clearly using the same antenna outdoors on 60ft tower. As for the digital systems the decoding sounds the same to me so as far as I can tell there is no change in the sound quality for digital transmissions.
