In an effort to conform to the undocumented convention of placing repeater output frequencies in
the VHF high band on the low side of a transmit/receive pair, in 2011 the County of Monterey filed for
license modifications to implement this convention. By doing so, the County anticipated that the radio
infrastructure would place it in a situation to reduce frequency confusion and possible interference issues
with other agencies. Funding and sites have been approved for this effort and
Goal
The users have agreed to fully support the changes mandated by narrow banding and the program to
rearrange the frequencies in a more compatible fashion. While most of the equipment is in place, the
inversion of the mobile relay frequencies is a very difficult transition due to the complexity of scheduling,
programming and installation of the radio equipment. This has made the original one year implementation
phase of critical concern.
Each County agency will have to be handled independently of the others. For instance, the Sheriff’s
office with their 500 radios, pose a major difficulty. The existing radios will have to be reprogrammed to
work with the inverted frequencies while not affecting communications as the repeaters are installed or
retuned.
There are 1300 mobile radios involved in this effort plus another 2500 portables throughout the
County and the cities therein.
While ordered in a timely fashion, the vendor for base stations has delayed delivery of their products
by 6 to 9 months due to being a victim of counterfeit components that adversely affect their operation and
reliability. This is beyond our control and has resulted in unanticipated delays.
Waiver Request
As has been shown, the County of Monterey must, and hereby does, request a waiver for the
construction deadline as listed on the applicable licenses to address this most daunting task.
