Frequencies you've lost to HD on AM

I live in the same region as Crainbebo and like he experiences, I sometimes find 1390 and 1370 grossly interfered with by KRKO 1380's hash. It's not so bad that I can't DX those frequencies on some nights.

KFBK 1530 gets interfered with by KKXA 1520's IBOC, but KFBK is still audible here, as is KGA and 1510, which are mostly in the clear.

1170 has a lot of hash. Sometimes I have difficulty hearing KPUG Bellingham 1170 because of it.

The worst offender here is 1250 KKDZ -- their IBOC wipes out 1260 and 1240, and can sometimes be heard on 1270. Fortunately, they have to protect KWSU for much of the night, so during the mid evening it's not so bad.
 
KKDZ's HD seems to be turned off between sunset and KWSU sign off at 12am. Then at 12am, 1240 and 1260 are obliterated by KKDZ IBOC.

Is there a reason why KWSU signs off at midnight?
 
I'm not sure why KWSU signs off at midnight, but they are a public radio station at Washington State University, so maybe it's college policy.

In the past, KKDZ's predecessors went off the air from sunset to midnight to protect KWSU.

So it's one of the few stations left that still chooses to be a daytimer
 
WCCO at 550 miles makes WHAS at 80 miles very unpleasant to listen to at night. WFNI 1070 Indianapolis takes out 1060 and 1080 beyond repair. WLW at 90 miles demolishes 690 and 710 completely during the day...at night, sometimes it can be punched through. I was delighted that WTVN 610 Columbus,OH dropped IBOC...now I can once again hear 5KW WMT Cedar Rapids in the day at 350+ miles. 5KW WTVN's IBOC at 170 miles made WMT totally non existent during the day. Overall, I'd say WCCO does the most damage in southern Indiana.

Why would a station "choose" to be a daytimer?

Most daytimers are not fulltime because they just can't get any power at night, or too little power to cover anything useful or the cost of building a complex directional is prohibitive.

I've seen a few cases where fulltimers decided to become daytimers. Most have been cases where they could no longer afford the land for a night pattern or where the night operation was so limited as to be useless.
