This was posted on another group a while back.
I have no idea how accurate is is.

NOTES
1) A Star (*) indicates that that frequency is not
active in all states, or may be shared with another
NTIA Government-band user.
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 (usually on the 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, 149 and 163 MHz 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.
