Northeast Region including Maine, New Hampshire, Vermont, New York and Pennsylvania

This is the most complex and restricted area for CAP. Close attention must be paid to proximity to the Border Zone.
Simplex: Within the Border Zone, ONLY AIR 1 and CAPGUARD are authorized at full power and without restrictions, other than the 3000 foot AGL limitation. Note that there are extensive paging operations in Canada on AIR 1 and interference is likely, particularly in the vicinity of population centers.
All of the other CAP Simplex channels, with the exception of TAC 1, may be used within the Border Zone at 5 watts output power or less; however, airborne operation, even at 5 watts or less, has the potential to interfere with Canadian operations, and airborne use of Simplex channels other than AIR 1 and CAPGUARD should be minimized for this reason.
TAC 1 is in use throughout the NER area as a CAP repeater input, and operations on this channel must conform to the recommendations of the Region Repeater Committee or other Region authority.
Repeater: Within the Border Zone, CAP’s standard repeater input frequencies are not authorized, including the inputs to the Tactical repeater channels. Repeaters located within or immediately adjacent to the Border Zone have special, different input frequencies, and these channels can be identified by the use of Designators from R101 thru R108. These channels may be used by all CAP stations to communicate through the Border Zone repeaters, regardless of whether the station is inside the Border Zone or not.
Note that use of the Tactical repeater channels is also not authorized within the Border Zone, and only the special Border Zone tactical channel is authorized.
CAP aircraft are authorized to access Border Zone repeaters while within the Border Zone, however there is a 3000 foot AGL restriction on all such operations while within the Border Zone.
Altitude Restrictions: Within the Border Zone, CAP aircraft are only authorized to transmit below 3000 feet AGL.
Outside of the Border Zone, CAP is authorized to operate “occasionally” up to 12,500 feet AGL, HOWEVER -- CAP aircraft that access the normal CAP repeaters or utilize Simplex channels other than AIR 1, TAC 1 or CAPGUARD should be aware of the potential for interference to Canadian operations, particularly if they operate above 3000 feet AGL. Guidance from NHQ should be sought if a proposed activity has the potential to interfere with Canadian operations.

Great Lakes Region including Ohio, Michigan, and Wisconsin

Simplex: CAPGUARD and TAC 1 may be used without restriction within the Border Zone. CC 1, AIR 1 and AIR 2 may be used within the Border Zone, however Canadian operations at several locations must be avoided. These areas are defined as follows:
CC 1: 60 km fron Sault Ste. Marie, Leamington, Chatam, and Oxford (red)
AIR 1: 120 km from Sault Ste. Marie, Sarnia, Wallace Bug, and Windsor (green)
AIR 2: 220 km from Tehkummah, Watford, and Brantford (blue)

Note: Use of CC 2 is not authorized within the Border Zone, and airborne operations outside the Border Zone should ensure that interference to Canadian Operations is minimized.

All of the other CAP Simplex channels may be used within the Border Zone at 5 watts output power or less; however, airborne operation, even at 5 watts or less, has the potential to interfere with Canadian operations, and airborne use of Simplex channels other than TAC 1 and CAPGUARD should be minimized for this reason.

Operations on TAC 1 in Ohio and Michigan need to be aware of the use of this channel as a repeater input in Pennsylvania and restrict their use of it to preclude interference to CAP repeaters there.

Repeater: Operation on the input to CAP Repeater Channel 1 and the Tactical repeater are not authorized within the Border Zone, and all repeaters located in or near the Border Zone have been moved to Channel 2. Operations using the tactical repeaters within the Border Zone MUST utilize R64 or other authorized Channel 2 repeater frequencies ONLY.
Altitude Restrictions: Within the Border Zone CAP aircraft are only authorized to transmit below 3,000 feet AGL. Outside of the Border Zone, CAP is authorized to operate “occasionally” up to 12,500 feet AGL, HOWEVER --CAP aircraft that access Channel 1 CAP repeaters or utilize Simplex channels other than AIR 1, TAC 1 or CAPGUARD should be aware of the potential for interference to Canadian operations, particularly if they operate above 3,000 feet AGL. Guidance from NHQ should be sought if a proposed activity has the potential to interfere with Canadian operations.

North Central Region including Minnesota and North Dakota.

Simplex: Channels TAC 1 and AIR 1 may be used without restriction within the Border Zone. CC 1 and CAPGUARD may be used within the Border Zone with the following restrictions:
CC 1: 120 km of Minton (red)
CAPGUARD: 120 km of Halbrite (blue)
All of the other CAP Simplex channels may be used within the Border Zone at 5 watts output power or less; however, airborne operation, even at 5 watts or less, has the potential to interfere with Canadian operations, and airborne use of Simplex channels other than TAC 1 and AIR 1 should be minimized for this reason.
Repeater: The input frequency used for CAP Channel 2 repeaters is not authorized within the Border Zone and therefore all CAP repeaters within or near the Border Zone have been moved to Channel 1. Use of Channel 1 and Tactical repeaters is authorized within the Border Zone.
Altitude Restrictions: Within the Border Zone, CAP aircraft are only authorized to transmit below 3,000 feet AGL.
Outside of the Border Zone, CAP is authorized to operate “occasionally” up to 12,500 feet AGL, HOWEVER -- CAP aircraft that access Channel 2 CAP repeaters or utilize Simplex channels other than AIR 1 or TAC 1 should be aware of the potential for interference to Canadian operations, particularly if they operate above 3000 feet AGL. Guidance from NHQ should be sought if a proposed activity has the potential to interfere with Canadian operations.

Rocky Mountain Region, including Montana and Idaho

Simplex: TAC 1 and AIR 1 may be used in the Border Zone without restriction other than the 3000 foot AGL restriction.
CC 1: may be used except within 120 km distance of Minton and Maple Creek (red)
CC 2, AIR 2 and CAPGUARD: Not authorized within the Border Zone.
Repeater: The input frequency used for CAP Channel 2 repeaters is not authorized within the Border Zone, therefore all CAP repeaters within or near the Border Zone have been moved to Channel 1. Use of Channel 1 and Tactical repeaters is authorized within the Border Zone
Altitude Restrictions: Within the Border Zone, CAP aircraft are only authorized to transmit below 3,000 feet AGL.
Outside of the Border Zone, CAP is authorized to operate “occasionally” up to 12,500 feet AGL, HOWEVER -- CAP aircraft that access Channel 2 CAP repeaters or utilize Simplex channels other than AIR 1 or TAC 1 should be aware of the potential for interference to Canadian operations, particularly if they operate above 3,000 feet AGL. Guidance from NHQ should be sought if a proposed activity has the potential to interfere with Canadian operations.

Repeaters: There is no restriction on the use of CAP repeater frequencies within the Border Zone other than the 3,000 foot AGL limitation.
Altitude Restrictions: Within the Border Zone, which includes the panhandle, CAP aircraft are only authorized to transmit below 3000 feet AGL. Outside of the Border Zone, CAP is authorized to operate “occasionally” up to 12,500 feet AGL, however aircraft utilizing CAPGUARD should be aware of the potential for interference to Canadian operations, particularly if they operate above 3,000 feet AGL. Guidance from NHQ should be sought if a proposed activity has the potential to interfere with Canadian operations.
Note that the border zone includes all of the Alaskan panhandle.

Mexican Border Zone

The Mexican Border Zone is an area approximately 140 kilometers (90.1 statute miles) inside the U.S.- Mexican border (red line). Within this area, CAP must not utilize airborne transmitters above 3,000 feet AGL when operating on CC1, CC2, TAC1 or any on repeater channel. Note that the repeater output frequencies are not affected and may be used IAW CAPR 100-1 8-3b.
