Here`s an advance from my Thursday-weekly reports:
** U S A. 600, July 6 at 0450 UT, surprised to hear country music here, soon ID as ``Classic Country KSJB``; 0454 UT a fuller ID mentioning ``Now with improved signal and sound quality covering 25,400 miles``, then fades down. C&W music continues past 0500 UT and 0501 UT segue without any further ID.
``Covering 25,400 miles`` would be a neat trick, about the circumference of the Earth! They probably mean *square* miles, which if it were circular, which it isn`t, would mean a radius of 90 miles, surely too little for 5 kW at 600 kHz. Even the ``local`` contour is more than that at

Yes, it does seem something has changed, as this 5/5 kW U3 Jamestown ND station is a rarity here, where 600 is normally a tossup between WMT IA and KTBB TX (sometimes an annoying second apart with same network talkshows). In fact my only previous log of KSJB was inconclusive, Dec 30, 2012 as in
http://www.w4uvh.net/dxld1301.txt
NRC Pattern Book shows both day and night it`s a figure-8, NE/SW, which means we should normally be getting some signal to the south; with nulls toward Cedar Rapids and Saskatoon. This log was on the RF-569D, which permanently stays on a wall so that it favors N/S signals.
FCC info for facility 10778 shows KSJB is licensed for 5.0 kW unlimited direxional, but with APPlication for 1.25 day/0.5 night, ND2. Or rather the ND low powers are for Special Temporary Authority. It sounds to me like they have just gone back to the Unlimited license. This explains it from the Correspondence file of August 12, 2014:

``This is in reference to the request filed July 22, 2014, on behalf of Chesterman Communications of Jamestown, Inc. ("Chesterman"). Chesterman requests special temporary authority ("STA") to operate
station KSJB(AM) with temporary facilities.' In support of the request, Chesterman states KSJB(AM) is embarking on a technical update of its transmitting facilities which involves the replacement of all three towers, the phasing and matching equipment and the feed lines.
Chesterman requests temporary operation from another antenna structure located on the same property as the AM array. Specifically, KSJB(AM) requests STA to operate on the FM tower of co-owned FM station KSJZ(FM). A temporary nondirectional operation is proposed both day and night with a daytime power of 1.25 kilowatts and a nighttime power of 250 watts. [. . .]
The STA facility is limited to a non-directional daytime power of 215 watts and a non-directional nighttime power of 237 watts in order to protect Canadian station CJWW at Saskatoon, Saskatchewan.``
Nothing found about this at own site http://www.ksjbam.com/ but I see they have a polka show Sundays at 19-21 UT! And lots of farming stuff (Glenn Hauser, OK, DX LISTENING DIGEST)
