SUBJECT: OPS - Why simplex frequencies? Part 2/2
The solution is to use non-standard frequencies in the 2-
Meter band and other bands if necessary.
The simplex 2-Meter RACES plan was accomplished for
California by Dr. Dave Tyler, Ph.D., N6DRT. It has seven cells
(or groups) of thirteen frequencies each and every county is
assigned a specific group in letters A through G. Frequency 1
through 4 and 146.52 are common to all groups, as well as a
common alert frequency 145.695. The remaining 7 simplex
frequencies are unique to a particular group. County groups are
typically separated from one another by over a hundred miles.
The overall effect is somewhat like a very large cellular
frequency plan. In total, there are 57 frequencies and each is
identified by a frequency number, should you wish to maintain
frequency confidentiality over the air. For a copy, send a SASE
with fifty-two cents postage. It can be adopted in any state.
Most of the frequencies in the 2-Meter band are purposely
uncommon frequencies. Some fall on channels identified for
exotic and experimental purposes. We feel that the very limited
emergency-only use takes priority and there have been no
complaints.
Footnote: This plan is not usable in Southern California
because of the proliferation on non-standard repeater pairs and
link frequencies.
EOM
[AA4RE editorial footnote] The cellular plan is a great concept.
However the actual channels chosen don't work in Northern California
anymore.
