What needs done on the amateur radio digs? Happy to help.

Depending on the repeaters capabilities he can make anonymous phone calls via this repeater.
If there is a way to check the phone records of those repeaters (assuming they have this capability) you may have multiple smoking guns. That's my initial hunch on why he's using them. The spread and reach of those repeaters also would give him more anonymity. Higher frequency ham bands result in shorter distances allowable from repeater physical location. What bands are they? 10m, 2m,…?
