I tried this many times with both sentinals (both HP & SDS) to no avail. Neither append to favorites or delete from favorites were highlighted. The radio went back to Scanner master this morning. I'm keeping the Uniden scanners BC785D and BCD396XT, yes old radios but DEPENDABLE
No, I don't think so, HP-2 sentinal does not let me add or delete frequencies, I tried that last night. I'm using the antenna that came with the radio. How do I download sentinal for SDS, maybe that would work for me ???
