CAP practice in El Paso County

Not open for further replies.


Dec 19, 2002
I heard CAP on a practice mission today in El Paso County. Sounded like they put out a practice beacon on an unknown frequency and were coordinating their activities on 148.150 MHz as published on RR.

I don't know any of these guys, but one thing I noticed is that they operate from what I think is their base (blue mesa 500) on a repeater with a long repeater hang time, and their airborne and ground units on simplex (in some cases) and the field units are constantly attempting to respond to their base on simplex (output of the repeater) during the repeater hang time. This seemed to be very problematic since it's FM and the base many times was not hearing the field units and there were constant repeats (..."blue mesa xxx did you copy?") Perhaps someone here who knows this group can pass that on.

Also, since they were discussing several "channels" (like channel 1 and channel 8) and RR only lists one frequency (with no channel index) I did some searching and found the following list along with frequencies for practice beacons. Can anyone confirm if these are a national standard (as claimed in the link) and can be added to the Colorado listing? Looks like there are scattered listings in RR but no cohesive list.
