DOW Radio Collar's

[mikeATtleccdotnet]

Does anyone have information about the radio collars that Co DOW uses to track collared animals? We apparently have a number of Mountain Lions in our area that have such an apparatus and it would be nice to know if they are around or not…
Thanks,

Doing a google search on animal tracking collars, found one link that shows a freqency range. Hard to tell out here if DOW uses high power or low power freq. Anyway here one link.

One more link.

Most of the collars I have seen use 167.xxxx and do a low power CW chirp. To pick them up on most commercial equipment you need a CW or SSB mode to turn the carrier into a chirp. By using the chirp and AM it is easier to estimate a distance by ear than an FM signal would be.
Putting the frequency into an FM scanner or even a scanner you can set to AM may give you a static squelch pop if the unit is close enough there would be no tone or any other alert. A communications Receiver would give a chirp but having the static of an open squelch while waiting for the TX to come into range will drive any non-radio crazy people to distraction pretty quickly.
It might also be a bit problematic trying to get the frequency out of the local game management official, they usually don't want their collared critters disturbed and giving the public a way to track said critter probably would not be looked upon too favorably.

I haven't looked for it lately, but the frequencies use to be listed in Part 90.
