(From the March 2000 "Service Search" column by Larry Van Horn, MT Assistant Editor)
The Fall low band skip season is upon us, and if you live on the East
Coast, you will frequently get daily skip reception from the famous California
Highway Patrol (CHP). This month's Service Search profiles the CHP low
band radio system. Information presented is courtesy of the VHF Skip (www.egroups.com)
internet newsgroup via Ian Julian, CRS Government Radio Systems (California
State Agencies) from Mobile Radio Services by Robert Kelty, and the 2000
Police Call Southern California Detail Edition by Gene Hughes.
