COMMENT:  Using Grove's "Federal Frequency Directory" 2nd edition
as a reference source:
172.7750 Looks like it might be an assignment to USCG (homeland security) or 
the Interior Department/ National Parks Service.  Might be some sort of 
remote security or maintenance type alarm.
170.7750 Could be FBI, ICE, USPS, again perhaps some sort of remote alarm?
163.750 Could be FBI, ICE, etc, again some sort of remote alarm?

Not sure how curious folks are on trying to figure out what agency/building 
is sending out data signals BUT this would be a very significant 
challenge!!!! :) ;)
