From The RadioReference Wiki
One wonders if the University of Harvard Police department is DES/OFB encrypted as a "challenge" to the students. :) --Blantonl 18:24, 20 May 2009 (CDT)
Doesnt Philadelphia PA FD encrypt their fireground channels? (I see San Francisco FD listed with 2 encrypted channels).
Forney PD in Kaufman County Texas is listed as encrypted in the radioreference database.
