Nothing seen here in Grand Junction
I had my computer up and monitoring Site 201 all day with Pro96 Com and saw nothing that looked like this test you mention.
The only traffic I saw was some CSP 5B Dispatch traffic for a couple hours.
Im not sure why I get the various front range CSP TGs once in a while, but for the last couple days it was CSP 6B Dispatch.
The TG's seem to stay on the site for unpredictable amounts of time. The only thing I can think of is the a Tech in this area tunes a radio for one of the TGs and affiliates with it here for some sort of testing.
Those front range TGs seem to come and go, but sometimes stay for hours or days. I have also heard Sheridan and Ft Collins PD over here for a very short period of different days.
