Fw: The Desert Whooper Beacon 4095.65 KHz - Corrections  View Printable Version

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

much weaker than TOMBS on 9395; that would be Furusato no Kaze from

been off since at least Aug 11; no info on the problem or prognosis.

and another to 4980, at 4979-USB; as I suggested previously, if 4975 &
4980 come on at exactly the same time, that would prove 4975 is a spur
from WRMI-4. 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)

A man of few words, does not even say what language. However listed in
last year`s NRC AM Log as SS:MEX, 10 kW ND daytimer, 1 kW critical

Afghanistan International TV puts VG signal into Kuwait SDR, S9+15/25

continuous talk, including female voice about Topic A, some crowd

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

Ron Howard then found this info about it but failing to mention SW: we

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

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,

remaining on air while the others are off also implies the separate
