There always seems to be the misconception that CAP is going P25
CAP went Narrowband and dual mode. [CTCSS FM with the ability to also [when needed] use P25] All of the Repeaters were converted
148.1250 is now the Primary Rptr Pair with 148.1500 being a Secondary Pair. As of Oct-2009 all wideband ops were to cease and depending on the availability [since most used converted amateur radios] the weekly nets have become sparce with traffic.
I would say program all the channels listed in the WIKI and see what you find/hear. Some of the simplex channels seem to be used more-and-more when Aircraft are up, with the Repeaters used for NET Nights.
Best of luck hunting...
Any confirmed Civil Air Patrol frequencies for the Lafayette (IN) Composite Squadron?
Are they still on 148.125 or 148.150, or have they switched over to P-25?
