As from today World Music Radio (WMR) is back on 15790 kHz (Saturday-Sunday
07-20 UTC) but with 10 Watts only.

The 927 outlet in Hvidovre, Copenhagen, went off the air on August 16th. Is
expected back on the air on September 2nd.

The two other frequencies of WMR - 5930 kHz (200W) and 25800 kHz (100W)
continuous transmitting round the clock. Also Radio208 is on the air
continuously on 1440 kHz (currently half power: 250W) and 5970 kHz (100W)

Something`s always wrong at WMR/Radio208 - but still keeping SW and MW
alive.

No nothing from WMR on 15790 kHz this weekend. It may take some time before
WMR is back on 15790. Meanwhile WMR is still audible 24/7 on 927, 5930 and
25800 kHz.

Die US AGM Monitoring Log Tabellen zeigen als Lokationsstandort (XXX)

Die Frequenzangaben in dieser Collage basieren auf Deinen Messungen.
Der Qatar4-SDR empfängt anscheinend etwa 54 Hz zu tief.
Als die Greyline ~ durch ARM/Katar ging gab es einen kurzzeitigen
signifikanten Feldstärkeanstieg.
ARM von 1430-0230z ist damit ziemlich sicher.
Etwas unklar noch die Lage 0230-1430, könnte Tashkent sein, oder etwas

Leider gibt es keine guten Tageslicht-Ressoucen für TDoA für 7600 kHz.

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
