Soooo all that new mult-tone activity is NOT US hams but operators from other
countries.. they seem to have very strong signals in DM97nx
Using HRD-DM780? I am unable to decode 95% of these signals. Guess those years
working telecom for a major multi-national and ASA-NSA prior to that were
wasted.

If the RMS had working busy channel detection and actually had it enabled,
against the directive of the network admin, the connection should not take
place if the frequency is occupied. I could be wrong though.
