Speaking personally...
Longest AM HD: KOA, Denver, CO, 802 miles. Haven't hooked up the AM loop to my XDR-F1HD in about four years, though...I think I've seen the HD light flashing on WBZ before
Longest FM Es: Unknown, since I apparently stopped logging FM HDs earlier this year, but the farthest I made a note of is KSRZ-96.9, El Campo, TX, at 1257 miles. I think I've received HD audio from FL though...
Longest FM tropo: KXNE 89.3, Norfolk, NE, 397 miles, 8/1/11. Now it would be next to impossible with newly 24 hour WGZS-89.1 and WRFJ-89.5.
Longest FM (normally): KCMP 89.3, Northfield, MN, 148 miles, though probably not any more with local WGZS-89.1 having signed on...
