On what AM stations have you heard DA proof of performance tests over the years?
Going way back to the late 60s or early 70s, I heard:
WITL 1010 500 watts DA-D Lansing, MI when they moved from Collins Rd. to Pine Tree Rd. Normally I was in a deep null. Fairly strong ND. About 1970.
WAAM 1600 Ann Arbor, MI when they moved from Washtenaw Avenue with 5 kW D, 1 kW N, DA-2, but operating with just 250 watts ND STA after a fire, to near Merritt Rd. and Platt Rd. next to US 23 with 5 kW DA-2. All of a sudden, there was a good signal again after a period of years as I recall. About 1973.
WTCM 580 Traverse City, MI when they increased from 5 kW Day to 15 kW Day, back in the 1990s.
WWJ 950 Detroit, MI when they moved from Royal Oak Township to Berlin Twp., and increased from 5 kW DA-N to 12/50 U4, and then 50 U4 in the late 1990s to early 2000s. Also maintenance and rebuilds since then.
WXYT 1270 Detroit, MI when they moved from Southfield to Ash Twp., and increased from 5 kW DA-N, to 50 U4.
WFDF Flint/Farmington Hills, MI when they moved from Burton to Carleton, and increased from 5/1 U3 to 50/19 U4 and then 50/25 U4, from 2005-2011.
WDRQ/WUFL 1030 Sterling Heights, MI, when they signed on in 1988 with 5 kW DA-D with two towers, then several years ago when they changed orientation and pattern and went from two to three towers.
There was a Canadian station I heard on STA ND, but I can't remember which one. I'll ask the person who I talked about it with whether he remembers which station it was.
