This is about 6 hours of audio (real time), and around 18 minutes with the gaps removed. Callsign of the month is Cheetah. Also heard are planes with
"Crimson" callsign, and at the NTS Casper. In addition, Balmy Breeze and Sidewider Ops.
This is an AAC file, which many phones can play these days.
For older devices, here is the same file in MP3 format.
Many browsers will stream MP3 directly. AAC usually requires a download and then VLC.
When you get to the part where the plane sees a sudden change in the wind and Groom reports a dust devil being spotted, all hell broke loose in the
general area. I could see half a dozen dust devils from my vantage point, all starting up at once. One was at the Sand Spring dry lake near Rachel. A
huge dust cloud ended up visible over the range near Bald Mountain.
In the recording, the tower has severe multipath. You can still make out the audio, but it is distorted. There comes a point where the tower is
warning a plane that the small arms range is hot. The plane can't copy. At that point, the tower becomes clear, as if there was a change in
transmitter location or they boosted power.
I suspect Groom analyzes all their recordings that get posted and may have tried to limit how much RF spills out to prying eyes, er make that ears.
They could reach Arizona, Utah, and California from Bald Mountain if they really wanted coverage.
I have some Red Flag audio that I will post in this thread. Boomer will get all excited hearing the word "MARSA". ;-)
