My DV-1 was hanging on a frequency after scanning for a few minutes. I patiently loaded and tested every firmware from 1907B - 2205A. Same issues. My order of banks by mode was 1-P25, 2-FM, 3 TETRA, 4-AM. I found that the DV-1 was hanging on an AM bank of memories (specifically 121.5 AM) which followed an 800 MHz TETRA bank. I swapped banks - AM first then TETRA as the last bank, and no more hanging on AM. I run 1907B so I can run the eSPYonARD software.


My DV-1 also sometimes "hangs" on a frequency after scanning for a few minutes too.

My DV1 is always in Memory Scan and every so often I find it stopped with a low carrier and a sort of roaring noise. Every time lately that it happens I have noticed that it seems to be on a channel in the FM mode (regardless of the bandwidth used). I have been switching these channels as I find them over to Auto mode. Hopefully this maybe a cure. So far ive not seen a lock up on other modes apart from FM. Maybe something to note next time yours locks up?

Yep, I need to investigate this issue further...
