[Scan-DC] Surveillance in Prince William County

[John Wilson]

    What you are hearing is the FBI Academy and/or DEA Academy
agents in training at or near Quantico MCAS.  The correct
frequency is 172.200 mhz. and can be either a repeater mode with
171.450 mhz. input and 167.9 pl. or simplex on 172.200 mhz.,
167.9 pl.  This is one of several 170 mhz. range infrequently
used frequencies for training agents in surveillance activities.
It is a fox and hound type activity where agents in training role
play and track a mock suspect.  What you hear depends upon the
training requirement for that particular day/week time period, if
any.   I am sure they now have the capability to go DVP, but
possibility are using older non-DVP equipment dedicated for agent
training.   When they use the repeater mode I can hear it at my
location approximately 90 miles south southwest of
Fredericksburg.  Don't get excited, it's all pretend.  For "real
life" situations, it is unlikely agents in training would
participate and actual agents involved would use DVP comms.
