    NOTES:
  1. The Missouri Wing (in the "North Central Region" [NCR]) uses CAPFlight call signs 2301 - 2399, Illinois (in the Great Lakes Region [GLR] ) uses CAPFlight call signs 1101 - 1199.
  2. (*) This frequency is not active in all states, or may be shared with another NTIA Government-band user.
  3. HF frequencies are window (or carrier); the center of the intelligence is 1.5 KHz above the listed frequency.
  4. (**)CTCSS tone of 203.5 Hz has been reserved as the input tone for transportable repeaters.
  5. 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.)
  6. 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.
  7. CAP and NTIA have just begun installing the new 26 MHz AM radio gear in CAP vans, so right now (December 2002), there is very little activity on those channels, as well as the 419 MHz channels.
  8. In the spring of 2003 CAP signed a $1 million contract with EF Johnson of Waseca, MN, for their 5300 series digital (P25) capable VHF radios.
