The California Highway Patrol

The Fall low band skip season is upon us, and if you live on the EastCoast, you will frequently get daily skip reception from the famous CaliforniaHighway Patrol (CHP). This month's Service Search profiles the CHP lowband radio system. Information presented is courtesy of the VHF Skip (www.egroups.com)internet newsgroup via Ian Julian, CRS Government Radio Systems (CaliforniaState Agencies) from Mobile Radio Services by Robert Kelty, and the 2000Police Call Southern California Detail Edition by Gene Hughes.
