[IRCA] Mostly Mexican MW DX to Enid OK, August 26-September 1, 2016



--- Begin Message ---
These logs are excerpts from my daily all-band reports, mainly SWBC, also VHF/UHF, sometimesÂutility, ham, which may be found in several archives without much delay, such as
http://www.hard-core-dx.com/index.php?topic=Hauser

And compiled weekly along with extensive news from many other individuals and publications in DX LISTENING DIGEST:

All my MW DX reports starting August 2011 are archived in this forum with open access:

All times and dates strictly UT. Rx: mostly DX-398 with internal antenna only or PL-880; NRD-545 with ALA-330S inside E-W or inside randomwire N-S; Nissan stock caradio as specified; ICR-75Â E-W longwire

** MEXICO. 680, Aug 29 at 1207, ``informaciÃn de Sinaloa``, 6:07 timecheck, opening newscast, i.e. XEORO, Guasave, 1000/500 watts per IRCA Mexican Log 2015 (Glenn Hauser, OK, DX LISTENING DIGEST)

UNIDENTIFIED. TP carrier search August 29 at 1140 UT: JBA on 774 from NW, so NHK; very weak on 882; at 1146 west on 702 so Australia or NZ, and 666. But something on 594 seems to peak N/S --- that can`t be right. Those were on the DX-398. Then at 1151 I find whether I can hear any of them on the R75 with E-W longwire: yes on 774, 702. Today`s Enid sunrise: 1201 UT (Glenn Hauser, OK, DX LISTENING DIGEST)

Now it dawns on me this could well be the megawatt in Chinsurah, INDIA: ``Akashvani Maitree channel on 594 kHz beamed to Bangladesh``

Grayline would work, as sunset in Kolkata is about 1225 UT, and sunrise here 1202 UT. Make that trans-polar! The path goes about 5 degrees from the North Pole, across Cold Bay and The Pas in Canada, 13440 km or 8351 miles to Enid; 74.4 watts per km, or 13.44 meters per watt (if it were strictly along the surface) (Glenn Hauser, OK, DX LISTENING DIGEST)

Walt Salmaniw, Victoria BC, replies: ``Glenn, I don't think any of us on the PNW coast have ever heard [India] 594. Much more likely this time of year are DU stations. Normally in the Fall/Winter, it's a major NHK frequency. Perhaps Patrick Martin [OR] just might have heard your station?``

Well, this was looping too far north for Japan, and certainly for Down Under. Will try to refine the DF if I have another chance (Glenn Hauser, DX LISTENING DIGEST)

UNIDENTIFIED. 594, after receiving a carrier from the north Aug 29 at 1146 UT, which fit for the megawatt from Kolkata along the grayline, on Aug 31 I`m up early to start monitoring at 1130, a semi-hour before local sunrise: today there are no `regular` TP carriers like 774 Japan or Australia, but 594 is back! It`s right on 594.0 as I calibrate the DX-398 USB offset clix against 540.0 XETX. 

This is a very steady but weak signal, far too little to pull any audio. If only they would/could cut carrier for a ``CW`` ID test. Repeated DFing puts it slightly CCW from due north, about 355, which is exactly the direxion of Kolkata. I`m expecting it to be fading out by 1230 --- but it doesn`t. In fact still there at ``full`` strength by 1300, 1337, 1420 --- and in full daytime. 

Unless it`s groundwave (hi hi), can`t be Kolkata, but something much closer. Occurs to me that my local 960 KGWA is about the same angle from here, could be spur from it? I walk around the block and find the same signal and angle, so it`s not from within the household. I`ll be driving around Enid to see if it`s stronger near KGWA site and if the DF change significantly. -366 kHz would be an odd spur, and there is nothing at +366 kHz = 1326. 

I conveyed the disappointing news to IRCA group et al., where several stories came in of other cases involving inexplicable carriers on 9-kHz bandplan frequencies which did not/could not turn out to be real DX, and will put them in DXLD. 

There 594 is again, Sept 1 around 1250 UT. Another reason India was unlikely, from Sudipta Ghose, VU2UT: ``The 3 x 400 kW transmitter of AIR Maitri uses directional antenna pointed towards East. The configuration is generally 2 x 350 kW using a combiner. In very favourable situation it is likely to propagate to Pacific as my fertile brain imagines``.

Another idea: harmonic from a longwave beacon? Bill Hepburn`s list shows the only one on 297 kHz is NH from Nouakchott, Mauritania. How about 198 kHz x 3? Only North Carolina, and China. Ken Zichi of MARE logged a DGPS in Bobo, Mississippi on 297. And nothing audible here on either LW frequency at 1825 Sept 1 (Glenn Hauser, Enid OK, DX LISTENING DIGEST)

UNIDENTIFIED. 594 kHz. Since it`s not INDIA, trying to locate the source of the carrier heard here even in the daytime: September 1 between 19 and 20 UT, I park a block away from 960 KGWA 4-tower transmitter site in NW Enid, but too much noise, probably overload, to hear it at all. Due east of KGWA, I can hear it and the DF is still about the same from NNW, so that rules out a KGWA spur. Also about the same DF from downtown Enid. This indicates it is some distance away, and could also be SSE rather than NNW, with this bi-direxional ferrite DFing on the portable DX-398. Will check further from other areas (Glenn Hauser, Enid OK, DX LISTENING DIGEST)

[altho this turns out not to be non-domestic DX, I am including it here as relevant to split-frequency foreign DXing]
