FRS and the higher powered GMRS operate in the 450 MHz range with analog FM.
Only individuals can obtain GMRS licenses, not associations or commercial
users. The range is strictly line of sight and can be shortened by tees
which absorb the signals.

Check with your public safety agency to see what systems they use. You want
to be able to talk back to the search base and to others in the field. We
used to call this communicating, now it is called interoperability.

In woods and moderate terrain 150MHz simplex (non-repeater) FM seems to work
best. It is not affected by trees as much as higher frequencies, the radios
are relatively cheap to obtain, they are public safety radios and the
channels are often already licensed by a public safety agency in the area
that will let you use their license on calls. Another advantage is that
these radios are stocked in the National Fire Cache and can be made
available on request from the NFS.

Newer systems, such as trunked radio, are exceedingly expensive per unit and
require that all units be registered with the system controller. My home
county is providing 2 800MHz trunk portables to every response agency that
agrees to a region wide response plan. This is a $5000 incentive in radios
alone.

Subject: Re: [MSAR] GPS training


I think everyone should - at minimum - know the basic use of the GPS,
including being able to note the Lat/Long and translating that across to a
paper map location. Hands-on training, repeated periodically to reinforce
the training.

Basic uses for Garmin Rino in SAR include:
- You can program a search route to follow.
- You can program the GPS to track where you actually go, which can be
downloaded into a laptop later as a record for that search.
- Use the radio function to communicate within / between teams. (Consider
investing $80 in a GMRS license to use the longer distance transmission
capability.)
- Use the locator function to keep track of where the personnel are (this
transmits only on FRS)
- Make a habit of reporting the team's Lat/Long when you call in
