Another unrestricted CAP article indicated that CTCSS 100 Hz would be replaced with NAC $3E8 as the common squelch on repeaters but would not be used for local communications, and that the new equipment would be dual-coded to respond to $3E8 for initial contact and a locally assigned NAC for general use. Tactical repeaters would be using NAC $7F3.
Other open-source articles indicated that other new equipment will include low-band military-type transceivers operating 26 MHz AM and 38-41 MHz FM. These would be installed mainly in aircraft and communications vehicles. Original source material (still valid?) for the new frequency assignments did not show 154.28, 156.# marine, or 155.475 among the programmed frequencies.
Actual very current frequency information has been made unavailable due to security concerns; only those with proper credentials signed in to official CAP websites can access this information, and several memos have been issued (starting around 2004-2005) reminding members not to disclose frequency information.
Based on the information given in the link on this thread, even if CAP had OTAR capabilities in the event of a need to change frequencies, the problem is that all of their radios would have to be re-keyed to maintain the 100% standardiziation across all groups, wings, etc.
