CAP uses 100.0 hz PL as a nationwide standard. All CAP repeaters have to
respond to this tone but it is only to be used by low power portables (less
than 6 watts with internal antennas) and when out of your home area. Each
repeater also has a normal tone (one of the 32 standard PL tones) which is
what you will normally hear. Some CAP repeaters do not tranmsit PL tone
but do require it before repeating.

CAP uses 148.1375 as a Ground channel and 149.5375 as Air-Ground. Both of
these are supposed to transmit 100.0 hz also but some radios may not be
programmed correctly.

CAP still has 26.620 but it is little used. They also have several HF
freqs from 2 to 14 MHz and these are used for long range communications in
USB.

Finally, CAP also has some "inter-squad" radios. These are basically the
same as FRS except they are on federal freqs right around 400 MHz.

Oh yeah, CAP also operates practice ELTs on 121.775 for training.

The Civil Air Patrol (CAP), an auxiliary of the U. S. Air Force,
has conducted several drills on the
two frequencies attributed to them , CH 1 148.150 and CH 2 148.125,
with a PL for the
New Hampshire wing of 136.5 hz ( Mass Wing and others may us the PL
tone of 100.00 hz)
this past month in Southern New Hampshire.

You may also want to plug 143.9 MHz in -- that's the input frequency for
the 148.15 repeater output. I don't remember the other VHF input, but
it's pretty close to 143.9. MARS repeaters use frequencies very close
to these, also.

Also, if I remember correctly, 123.1 is a common frequency in the VHF
aircraft band for "tactical" use by CAP aircraft and for air-to-ground
communications. And of course, ALWAYS keep 121.5 programmed in, along
with 243.0 if your scanner covers that band -- those are the VHF and UHF
"GUARD" frequencies for aircraft emergency communications.

Long, long ago, CAP also used 26.620 MHz. This was made available by
using old crystal-controlled CB radios and putting the channel 10 CB
crystals in backwards (put the Rx crystal in the Tx slot, and vice
versa). I believe this frequency has long since been dis-used, with the
advent of less expensive VHF FM gear and the passing of crystal-
controlled CB equipment into the sands of time.

Good point about the FRS frequencies. I'll remember that tip, thanks.
