How far is your 2M antenna from your P3?

A suggestion. Try adding several clamp-on ferrite cores to the power 
cable and the BNC, placing them as close to the P3 as practical.  These 
should be a SINGLE TURN for 2M (that is, simply clamped onto the cable), 
two turns for 6M. IF these cables are radiating the trash, the cores can 
help reduce it.
