Saturday, August 21 2021
----- Forwarded Message ----- From: Desert_Whooper <desert_whooper@protonmail.com> To: wghauser@yahoo.com <wghauser@yahoo.com> Sent: Thursday, August 19, 2021, 06:37:05 PM GMT+1 Subject: The Desert Whooper Beacon 4095.65 KHz - Corrections
Hello Glenn!
In your August 4th logs a person offered some incorrect information about DW's transmit format. For your readers' interest, here are some technical details of the one watt beacon that provides fascinating propagation performance.
The beacon started development in November of 2020. It was built from scratch and has a hybrid controller consisting of two 555 CMOS timers to key the transmitter along with an Arduino Nano controller to generate Morse code and collect data for performance telemetry. The 555 timers will independently key the transmitter if the Nano fails for any reason. (Fortunately the Nano has functioned for 10 months without issue.) The 4.09565 MHz transmitter is crystal controlled and features a MV1403 varactor diode circuit for the upward frequency sweeps of 150 Hertz. The sweeps provide distinctive audio for the SWL'er as well as an easy to spot visual pattern on the waterfall display of Kiwi SDRs. The transmitter has 4 transistors and the final amplifier is a IRF510 MosFet followed by a low pass filter, all inside a shielded box.
The beacon is powered by a sealed lead acid battery which is kept charged with a solar panel. The battery is protected from over discharge by a low voltage disconnect (LVD) circuit that is independent of the Nano. Time has shown that the solar panel size provides good charge current even in cloudy weather and the beacon does not draw much battery power overnight.
The antenna is a 111 foot long, 1/2 wave dipole oriented North/South and it's about 0.1 wavelength above the dry desert soil to create a more vertical but omni-like pattern. The 1:1 balun is home made and the antenna's measured VSWR is close to 1.1 to 1
There are six cycles of DW in Morse along with 29-30 "whoops"; then the DW identification is sent along with four different telemetry numbers.
Telemetry is in slow Morse code as follows:
BAT is the battery's voltage to tenths of a volt using a precision resistor divider and the Nano's A2D function. Normal values range from 12.8 to 14.4 volts
OTMP is in degrees F with a calibrated 10k NTC thermistor located outdoors, about 100' from the beacon.
ITMP is in degrees F provided by a digital one-wire DS18B20 microLAN sensor located within the weathertight equipment box. The reading runs 5 to 10 deg warmer than OTMP.
PV is given in milliAmps to monitor solar panel performance and battery charge current. Measurements are based on an INA219 current sensor board. The values of the current can range from 0 to 2000. Note that a value of 4 or 5 is just the idle current consumed by the solar controller because the battery is fully charged.
In case the Nano fails, the number of whoops can decrease from 30 down to 29 as a crude measure of rising temperatures. On some recent days the internal temperature has peaked at 120 degrees F when outside air temperature was measured at 112 degrees! The box is in shade but the electronic circuitry generates waste heat that causes the temperature rise. Monitoring the temperatures during night and day provides for some interesting deltas..
DW was officially deployed to the Western desert on February 21, 2021. It has been heard in Canada, California, Hawaii, Maryland, Utah, Arizona and many other locations. Some SWL logs can be seen here: https://www.hfunderground.com/board/index.php?board=9.0 and eQSLs are being provided.
Best regards,
The DW Team

** CANADA. 6754-USB, Aug 20 at 0414, Trenton Military more or less back to normal after several days of distorted modulation and ``no report received`` from anything, per other monitors. Now only partial NRRs and OK mod; but clock is still off: own time check at 0417Z as ``0415``. Haven`t heard it much on day frequency 15034-USB. CHR has gone thru such phases before leading to assumptions that it`s done for, but eventually recovers when someone fixes it, after vacation? (Glenn Hauser, OK, WOR)

I had already detected The Overkiller on both. YES! They both pop carriers on about *2358.5, 4975 JBA carrier, and 4980 with the WRMI IS & ID loop prior to ToH. This also answers my unID at the end of WOR 2100, recorded shortly before this (Glenn Hauser, OK, WOR) ** U S A. 1130, re my unID Spanish QRM to KWKH in the middle of the night, maybe one of 3 daytimers listed in Spanish, Powell E Way III, SC, reports on ABDX August 18: ``[abdx.org] WLBA Posted Wednesday, August 18, 2021, 7:20 pm abdx mail list 1130 WLBA Gainesville GA *blasting* in at 9:15 PM EDT .

However listed in last year`s NRC AM Log as SS:MEX, 10 kW ND daytimer, 1 kW critical hours, group: La Mejor [sic: Peor?]. So this could be the unID SS I had QRMing KWKH (Glenn Hauser, OK, WORLD OF RADIO 2100) This report dispatched at 0450 UT August 20

** AFGHANISTAN [non]. 7600, Aug 18 at 1526, new clandestine Afghanistan International TV puts VG signal into Kuwait SDR, S9+15/25 in SAM mode. Very slight hum. Bit of vamp music, seagull sounds, not sure if language be Dari = Farsi or Pashto. Should be both as time goes on. IDs in passing with English? name ``Afghan International`` and spelling out AFINTLTV. 1528 brief English clips from W and Obama about previous end of Taliban regime. 1530 at ToH in Afgh, theme and continuous talk, including female voice about Topic A, some crowd noise clips such as at 1603. Just what you would expect from a TV soundtrack. Still going with more of same past 1700. At 1725 a woman starts singing briefly. 1729 more clips of GW Bush about the Taliban takeover. 1730 maybe language switch? Still VG past 1737+.
This was first reported on 7600, August 16 and misidentified as a BBC frequency change. Arthur Pozner explained at 1705 UT Aug 17: ``The 7600 kHz transmission is NOT BBC. Supposedly originating from R. Afghanistan Intl and based in the UK. Transmission site may be the same as R. Iran Int'l, near Tashkent. The parent company of both programs is Volant Media UK Ltd.`` Ron Howard then found this info about it but failing to mention SW: we wonder if it can have more viewers by satellite TV now in Afgh? https://iranintl.com/en/world/volant-media-uk-launches-afghanistan-international-tv ``World --- Monday, 16 Aug 2021 20:42 Volant Media UK Launches Afghanistan International TV On Sunday, the day the Taliban captured Afghanistan’s capital Kabul, Volant Media UK Ltd., the parent company of Iran International TV, launched Afghanistan International TV (AITV). AITV aspires to serve as a 24/7 international news network to provide reliable information for audiences and protect media freedom in the country. With Afghanistan undergoing a chaotic transition after the US military withdrawal, AITV aspires to be a voice for the voiceless — to tell the story of the people of Afghanistan, as Harun Najafizada, AITV’s director tells Iran International TV. He revealed concerning reports of the Taliban’s tense relations with the media community and how independent journalistic activities have been severely disrupted. Afghanistan International TV crew at their broadcast station. FILE The situation in Afghanistan is so dire that AITV decided to launch the network prior to the planned start date — which was slated for the United Nations’ International Peace Day on September 21. The hope is that this will fill a media vacuum that has developed with so many people fleeing the country and will provide a critical source of reporting and information amid rapidly shifting events on the ground. AITV, which has started with daily nine hours of live television news and programs, plans to expand to a full 24/7 schedule as soon as possible. But AITV also has a radio stream which is already offering 24-hour news and programs. In terms of programming, Najafizada said AITV plans to rely heavily on reporting from across Afghanistan and to produce informative programs — talk shows, documentaries, and debates — to engage with people inside and outside Afghanistan. AITV will be an independent and impartial channel which will report facts, in keeping with standard journalistic norms. As to how AITV will fare with the Taliban in control of Afghanistan, Najafizadeh says it is not about AITV, but it is about the Taliban and how they receive the international media. AITV is prepared for any scenario.`` This mentions a ``radio stream`` but WTFK? No 7600 cited. Its span as yet unknown, nor whether there be any other frequency. As of Aug 18 there is still nothing in HFCC A-21 on 7600. Since Tashkent is only 756 km = 469 miles from Kabul, 7600 might work 24 hours (Glenn Hauser, OK, WOR) ** ANTARCTICA. 15475.98-RCUSB, Aug 18 at 1446, no signal this Wednesday from LRA36 into two Brazilian SDRs (Glenn Hauser, OK, WOR) ** CANADA. 248-MCW kHz, Aug 18 at 0621, WG, NDbeacon from Winnipeg is barely copiable due to current local blob over the frequency (Glenn Hauser, OK, WOR) ** KIRITIMATI. 846 kHz, Aug 18 at 0618, JBA carrier again from presumed R. Kiribati (Glenn Hauser, OK, WOR) ** U S A. 4096, Aug 18 at 0603, sweeps upward from the beacon formerly known as DW for desert whooper. JBA in noise level. 4102.8, Aug 18 at 0604, the ``W`` weather beacon also JBA, also sends various other letters and numbers (Glenn Hauser, OK, WOR) ** U S A.

It`s unclear whether the current 9330 transmissions with a lower-powered backup transmitter are coming thru the Ampegon high-gain antenna, or one of the regular antennas. The strength sometimes implies a lot of antenna gain is in play; and remaining on air while the others are off also implies the separate transmitter site for it (Glenn Hauser, OK, WOR) ** U S A. 9455, Aug 18 at 0612, WRMI-5 is still off the air; while 9395 & 9955 are unusually VG at this hour.
