I never picked up KOMO either when WCFL was off; nor XEOY or KTOK, but one Auroral-influenced night in came Radio Nacional from Manizales, Colombia, HJHF 10 kw according to an old guide.

I have not heard that one, but did hear HJAQ La Voz de Cartagena. That one was listed as 15 kW. The others heard during the WCFL silent period were KOMO, KTOK and XEOY.
 
In the early 70's in Tulsa, I heard KOMO one Monday morning. KTOK was never a problem for me as they were always poor at my location, despite being ~100 miles NE of them. XEOY was always dominant at night. Today, in Houston, XEOY is always on top.
 
My downstairs neighbors moved out today. They took the cute bunny-rabbits (😥), but they also took the LED Rope Lights and noisy power supply (😊).

I'm getting a fair-to-good signal from KBRE-1660, Merced, CA.
It was very good about 20 minutes after my sunset, until about ten minutes before theirs. It then got weaker and had some fading. It didn't seem to change much at their power change time (10 KW to 1 KW).

KTOK has a tight night pattern with a null towards the North East to protect WCFL/WMVP. Did you ever hear Chicago on 1000 in Tulsa?
 
Since WCFL/WMVP is/was 50000 watts, and has very shallow nulls in the Daytime, even more shallow now with the late Glen Clark's "new" Day pattern, I'm surprised it doesn't seem to have more of a Critical Hours presence to the West. As they say, you have to get up pretty early in the morning to get the skywave from the Daytime before LSR at points West though. And then you may have to contend with interference from Daytimers already on the air. But now that CH and Daytime Skywave DX is the easiest, it's something to consider.
 
Here in the Kansas City area, WMVP is quite listenable during critical hours when they are on day pattern. Additionally, I occasionally receive them mid day when "daytime skywave" occurs. Once on the night pattern, they totally disappear. I have been listening to station at the pattern change and "poof" they are gone. KTOK is rare here, XEOY is common at night. I have never received KOMO.

Being the radio geek that I am, I have frequently listened to power and pattern changes, and noted how noisy and how quick they are/were. It's not as fun as it used to be. You used to be able to hear several at roughly the same 15 minute interval by tuning around. Now most pattern changes are tied to the single WWV/atomic clock time, and occur simultaneously.

Yep....I remember one morning on a business trip making the run from Kansas City to Wichita toooling down I-35 in broad daylight about an hour after sunrise, listening to WMVP coming in almost like a local. I had no idea it would be there until it tripped the scan button in my rental car. It was good for a little over a half hour before it finally faded and never came back.
 
A little post-sunrise DX fun this morning on my car radio. About an hour after sunrise (8:00-8:30am CST). Mrs. Cyberdad in a store, Me parked in a conveniently open noise free parking lot. Good conditions to the west (although the first of these is east)....

610: WTVN: Good. Easily breaking through WTMJ splatter from 620. WTVN has always been very elusive for me.
860: KKOW: Pittsburg, KS (ex-KOAM). 10kw day oattern. Good signal. It's probably been 10 years since I've heard thus one.
880: KRVN: Weak, but overcoming WLS splatter
980: KMBZ: Kansas City Not a first for me, but very rare. Weak, but on top of WITY and WCUB. (Back to their original call letters after many years as KMBR).

Good catches! KKOW is very listenable here in south Overland Park, Kansas when they are on day power and non-directional pattern. When they power down and change patterns - poof! They totally disappear. KMBZ is now 9 kW on their non-directional day pattern. They put out a good daytime signal. They were KMBC prior to 1961 and they have been KMBZ since then.

Interesting article, Bob. Thanks for posting. Lots of "moving" history there. I didn't know about the relationship (shared time and TV relationship with WHB). I do seem to remember....or should have remembered....the years prior to 1961 as KMBC. 1961 was the first year I discovered DXing, so it may have already been in the first White's radio long in my possession in 1962.

Or...I may have just experienced a case of senior-itis. LOL.
 
Interesting TA catch this evening on the Warrington SDR in northeast England. WPTX from Lexington Park, Maryland on 1690. Very week with nostalgia format. First I matched th's e stream to confirm it. (Song was "I can't Stop Loving You" - Ray Charles, followed by "Yesterday Once More" - Carpenters.) Later, I caught a positive ID. This was at 8:00pm CST/0200 UTC. As I type this, it's now a half hour later, and the signal has been steady throughout.

This was my first visit to this particular receiver. Although I didn't hear anything else that I could identify from North America, this may turn out to be a good DX destination.
 
Check that about no other TA DX. WBBR is in on the Warrington SDR as I write this. Weak, but stronger than WPTX. Unfortunately taking a hits stronger adjacent channel signals on 1125 and1134

Nicely done and thanks for the heads up on this receiver. I'll be trying it out as there is little action this season from North America on the Arctic SDR.
