The experiment was to record 1210 kHz between 7:15 and 8:07 pm - Denver local sunset (me) is 7:30; Laramie is 7:45. I was already able to null out interference from KLDC at 7:15. There was a faint KHAT just before 7:30. At 7:31, I could clearly hear KGYN switch to DA-N because it suddenly came in and I could clearly make out the basketball PBP that it was airing (University of Connecticut vs. USC women's). Even so, the interference from KHAT seemed to pick up as well and, from time to time, dominated. KHAT's probable TOH ID shortly after 8 pm could be discerned but I couldn't really copy it. Didn't catch a KGYN TOH ID - it may have gotten pushed back since there wasn't a break in the game until about 8:06.
KGYN is a semi regular up here
