NOTES

1) A star * shows that the frequency is shared with another government
user nationwide and the CAP has second priority on that frequency.

2) Most CAP units are equipped with radios that can
operate on frequencies outside the government bands.
For example: a CAP aircraft may have a CAP radio, a
137-174 MHz VHF-FM radio (used to talk to other
SAR agencies) and a VHF-AM radio.  The VHF-AM radio
would cover 118-137 MHz, this way the aircraft can
talk to other aircraft that only have standard VHF-AM
aircraft band radios (usally on the 119.35, 120.85, 122.90,
and 123.10 MHz search and rescue frequencies.)

3) Most CAP vans and trucks have radios that operate
in the 143, 148, and 149 segments only, so these
are by far the most active of the channels.

4) CAP and NTIA have just begun installing the new
26 MHz AM radio gear in CAP vans, so right now, there
is very little activity on those channels, as well
as the 419 MHz channels.

5) The ISR (Inter-Squad Radio) channels are used nationwide by nearly every
government agency for low-power point-to-point communcations.
The NTIA issued these channels because FRS/GMRS radios are not allowed to be used
for government communications.  You may hear other government communcations
on the ISR frequencies. !DSPAM:435c29ac256001078415427!
