** CUBA. 6100, June 5 at 0553, RHC English is JBM, // with increasing modulation levels: < 6000 < 6165 < 6060; and 5040 is already off early. Something`s always wrong at RHC (Glenn Hauser, OK, DX LISTENING DIGEST)

** CUBA. 13660, June 5 at 1354, RHC Spanish is S8-S9 here and nearly 100% readable, despite being a leapfrog mixing product of 13740 over 13700 another 40 kHz lower. That`s because the fundamentals are blasting in: 13700 at S9+30/40, and 13740 at only S9+20/30 accompanied by some squeal. Something`s always wrong at RHC (Glenn Hauser, OK, WORLD OF RADIO 1933, DX LISTENING DIGEST)

** EAST TURKISTAN. I asked about the reception disparity between the two CRI French frequencies 17560 and 17650 from Kashgar until 1357*, as parameters in HFCC are identical except for antenna type. And got these replies, first from Peter W. Hanson on the WOR iog:

``Hi Glenn. Not much info on this on the web. In HFCC antenna folder,
216 is listed as AHR(S) 4/4/0.5 ;
288 is listed as AHR(S) 8/4/1.0 ;

AHR(S) which is a type of Fixed Curtain antenna stands for Aperiodic, Horizontal polarization, with Slewing.

Found a web page about Ampegon broadcast antennas: according to them, the bigger the first 2 numbers are, the longer the broadcast range is.

The first number is the number of 1/2 wave elements there are.
The second number is the number of dipoles stacked vertically.
The third number is the height above ground of the lowest dipole antenna measured in wavelengths``

And, FYI from Wolfgang Büschel:

``ITU Geneve SW antenna type explanation:

2.1 Type 1: Multi band centre/end - fed curtain antenna arrays with
aperiodic screen reflector

Designation: AHR(S) m/n/h, where:

m = number of half-wave dipoles in each horizontal row
n = number of rows spaced half a wavelength apart one above the other
h = height above ground in wavelengths of the bottom row of dipoles

slew angle and the design frequency are notified separately.

Centre-fed dipole array with aperiodic reflector
or
End-fed dipole array with aperiodic reflector

Curtain arrays of co-linear horizontal half wavelength dipoles arranged in a vertical plane in order to reduce the beamwidth of the main lobe and hence increase the directivity of the antenna. Directional patterns are generally obtained by the use of an aperiodic reflector. An periodic reflector is normally a screen consisting of horizontal wires which act as an untuned reflector.

The front-to-back ratio of an aperiodic reflector depends on such factors as: number of wires per wavelength, wire gauge, distance between radiating elements and reflector, and size of reflector. To achieve a front-to-back ratio, which approaches the gain figure of the antenna would require a screen density of about 40 to 50 wires per wavelength for the highest operating band of the antenna.

In practice a number of antennas of this form can be operated over a
maximum of five consecutive broadcasting bands giving an operating frequency range of up to 2:1. This range is limited by the performance of the radiating elements.

** OKLAHOMA. While hunting for Es from beyond OK, June 4 at 1918 UT, I run across some local info. 100.1, once a class-A, 3 kW channel, now has a 100 kW in Woodward, KWFX, abutting LPFM in Enid 99.9. One slogan heard, ``covering all the mesas`` which had me thinking of AZ or vicinity, but there are minor mesas between Woodward and Enid. Finally heard local ad with a 580-AC same as Enid.

Circa 1730 UT June 4, on headphones with the DX-398 set to stereo I find two of my locals are modulating left-channel only: 88.3, K202BY, with Family Radio talk; and 94.3 KLGB-LP with gospel rock music. Both still thus early UT June 6, with K202BY also musicking. They`d better hope signal is weak enough for listeners not to break stereo threshold, in which case lacking right is not so obvious. Axually, I`m sure neither station knows nor cares (Glenn Hauser, Enid OK, DX LISTENING DIGEST)

** SAUDI ARABIA. 11820.04, June 5 from 2205, BSKSA Qur`an with only fair signal, but supplying sufficient soporific singing to soothe my post-produxion nap. At some point there was a very long dead air pause; maybe some visual interlude perceptible only at ångström wavelengths? But chopped off the air in mid-Q at almost 2301*, like an alarum (Glenn Hauser, OK, DX LISTENING DIGEST)

** U S A [and non]. WORLD OF RADIO 1932 monitoring: not confirmed UT Tuesday June 5 at 0048 check the 0030 broadcast on WRMI 7730, since that frequency alone is unusually off the air (all other WRMIs confirmed at widely diverse strengths: 5010, 5850, 5950, 7570, 7780, 9395, 9455, 9955). 7730 still off at 0115; on by 0258.

WORLD OF RADIO 1933 contents: Alaska, Australia, Brasil, Chad non, China, Cuba, Germany, Guatemala, India, Iran, Italy, Japan, Korea North non, Kurdistan non, North America, Oklahoma, Saudi Arabia and non, Sikkim, Somalia, Sudan, Taiwan, Tibet, Uganda non, USA, Vietnam, Zanzibar; and the propagation outlook

WOR 1933 ready for first airing just in time for 2030 Tuesday June 5 on WRMIs: 7780 VP, 5950 JBA carrier. Repeat at 2130: 7780 still VP, 5950 a slightly stronger JBA carrier. 5950 is aimed WNW but absorbed in the daytime. 7780 is aimed NE toward Europe, so I check UTwente SDR: nothing audible at 2030 (while 9395 aimed NNW is detectable); at 2149 there is now a trace of me on 7780. Surely 9 or 11 MHz band (like ex-11580) aimed toward Europe now would do much better into the trans-Atlantic summer Eurevening; as well as up the eastern seaboard.

Just as I had given up on WBCQ 9330, checked anyway Tuesday June 5 at 2330 --- there it is on 9330.104v-AM, the new WOR 1933, good and in the clear without any BS mixing. Affiliates including WBCQ had been notified 2+ hours earlier that 1933 was ready, evidently spurring a boardop to axion; but don`t count on WOR repeating almost every day at 2330 as Allan originally scheduled. Next:

Wed 1030 WRMI 5950 to WNW
Wed 2100 WRMI 9955 to SSE
Wed 2100 WBCQ 7490v to WSW

** U S A. 17775, June 5 at 1356, KVOH is on early, prélude of praise music in Spanish, peaking S9+10 but with some deep fades (Glenn Hauser, OK, DX LISTENING DIGEST)

** U S A. The 6 meter sporadic E map shows huge openings all across the US, June 4 circa 1700 UT. I tune the lower FM band from my perch on the porch with the DX-398 and PL-880 but no DX detectable on the few semi-clear frequencies. Better luck an hour later on the Nissan caradio, as I finally ID some FM Es DX this year:

90.3, June 4 at 1759 UT, overriding my weak Okie, ``Nevada Public Radio, KNPR`` promo and 11 am timecheck. Looked up later in the WTFDA FM database, there is no NPR NV on 90.3 – KNPR is on 88.9 in Las Vegas NV, but bound to have translators/relays --- but the only NV on 90.3 is K212AM in Carlin etc., 46-watt translator of KCIR 90.7. Could it be taken over by KNPR on a 90.7 output/input?

Let`s look at the NPR coverage map:
https://knpr.org/about/stations-coverage-maps

No 90.7, but there *is* one on 90.3, and it`s extra-Nevadan in St. George UT, KSGU! Where they have to put up with PDT timechex in the MDT zone. And it`s only 2 kW H&V! at 555 m HAAT. So really in Utah? Coördinates 36-50-49 & 113-29-28. The NV/UT border is almost 114 west; but the AZ/UT border is right on the 37th parallel, so site is really in Arizona! 37 N is also the KS/OK border. St George itself is 1400 km = 870 miles to Enid. What else?

92.7, June 4 at 1815 UT, Spanish, 800 number, California gas prices, 1817 ad with 702 area code, 1818 ad address on West Sahara; 1820 Goodwill PSA, all in Spanish. For a moment it sounded like there was a second SS station. This one is obviously Las Vegas NV. O yes, I`ve DXed this before, la emisora doble, per WTFDA FM Database:

KRRN 92.7 MOAPA VALLEY NV 100.0 kW horizontal only, 587 m HAAT, 36-36-04, 114-35-06 Spanish REGIONAL MEXICAN RADIO LA SUAVECITA --- and a co-channel relay/booster in Las Vegas proper, 92.7 KRRN-FM2, 20.0 kW H&V, HAAT unknown, at 36-20-00, 115-21-41. Moapa is on I-15 NE of LV almost halfway to St. George UT. If it`s Moapa Valley, 1483 km = 922 st mi to Enid.

93.1, June 4 at 1801, Las Vegas, iHeart promo. WTFDA says it`s KYMT, 24/24 kW, 1141 m HAAT, ``93.1 The Mountain``. Licensee is Citicasters, but that appears to be a subsidiary of bankrupt iHeart. Signal surge peak overcomes fringe My 93-1, 100 kW KHMY Pratt KS. 1547 km = 961 st mi LV to Enid.

94.1, June 4 at 1914 UT, ``Mix 94`` partial non-ID: got to be KMXB, Henderson NV, 100/100 kW, 354 m HAAT. Mix 94.1 slogans also apply to stations in OH, NH --- and Amarillo TX. 1535 km = 954 statute miles Henderson to Enid, i.e. ideal mean skip distance for FM Es (Glenn Hauser, OK, DX LISTENING DIGEST)
