I have been setting up the scanner since Pro Scan made NXDN support available, and have been seeing this oddity continue. I don't have DSD+ running, but on some random talk groups if a conversation is occurring, it flashes the talk group for a split second, then continues to scan (ID Scan Mode), when it returns to the talk group, I'll hear the end of the conversation. Non-specific talk groups it occurs on too.That would make it appear to me it's ignoring conversations in progress and none of the talk groups are encrypted.
I'm sure their will be future firmware upgrades, and hopefully this along with a few other tweaks can make this nearly perfect. This is a NXDN 4800 system, and don't know of any 9600 systems I can try this on in close proximity.
Other than that, I continue to be impressed of how good this decodes and follows conversations with the rare exception of whet I described. By no means is this a complaint, but a suggestion for the future upgrades which will probably occur.
