From Cheyenne, WY:
It's KTRR "Retro 102.5" in Loveland, CO (37.9 miles away) with a moderate signal all over. I can occasionally get their HD to lock. This definitely makes it viable alternative to KIGN (just 3 spots down the dial at 101.9) or KRRR (104.9).
I don't have any tropo or E-skip loggings at this time.
Travel: KTRR pushes it's way into the North Denver suburbs before it fades away. In Estes Park, KTRR is fairly consistent.
In Riverton, WY, the K273BY translator (Pilgrim) is surprisingly strong at the college over there.
In Sheridan, Scottsbluff, and Rapid City, 102.5 is just splatter from a local on 102.3 or 102.7.
During my trip to Capser, it was KHOC "Heart Radio" of course, however it seemed to pack less signal than Casper's other 100kw stations.
