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,

Hauser
** 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)

** NORTH AMERICA. 6948-USB, Aug 20 at 0000 tune-in to some classic
rock, Henry VIII I Am, 0002.5 Let`s Do the Twist, 0010 Runaway; 0025
Mr Tambourineman; still past 0040; 0026.6 an unreadable ID. S6-S9 on
both receivers, but vs high storm noise level. Many logs here:
https://www.hfunderground.com/board/index.php/topic,85283.0.html
as Cool Oldies, via Mix Radio International (Glenn Hauser, OK, WOR)

** NORTH AMERICA. 6935-USB, Aug 20 at 0412, rap and other music, S4-S5
into Maryland SDR, then fading down. Back up by 0433 ID missed and
gmail; 0439 ``You are listning to Radio Genix`` and more music,
``Radio Ga-Ga``. This was reported not later than 0235 here:
https://www.hfunderground.com/board/index.php/topic,85285.0.html
Unusual for a pirate to be on this late, strangely enough; seems the
NAm pirate scene is not for night-owls (Glenn Hauser, OK, WOR)

to: Glenn Hauser, Box 1684, Enid OK 73702 USA

First broadcasts confirmed UT Fri Aug 20 at 0130 on WRMIs, 5850 VG
direct; and 7780 VG S9+10/20 via UTwente. Argentine en français
ensuite par 7780 (Glenn Hauser, OK, WOR)

** U S A. 4790-, Aug 19 at 0552, this WBCQ is off, but 6160- is still
on with TOMBS, 9330- also on JBA; 7490- off as supposed to be; nothing
direct on 3265, nor at random chex otherwhens even via nearby
remotes.

At 0409 UT Aug 20, to Maryland SDR, no signal on 3265-; 4790- and
6160- and 9330- are on (Glenn Hauser, OK, WORLD OF RADIO 2100)

** U S A [and non]. 9455, Aug 19 at 0554, WRMI-5 is still off while
9395 & 9955 are audible, but poorly. 1351 recheck, algo JBA on 9455,
much weaker than TOMBS on 9395; that would be Furusato no Kaze from
Japan via TAIWAN for Korea North, as sked until 1358. 9455 WRMI has
been off since at least Aug 11; no info on the problem or prognosis.
It`s dispensable with TOMBS or SMTV except for two hours of the 24
with variety of programming scheduled: 00-01 & 09-10 (Glenn Hauser,
OK, WORLD OF RADIO 2100)

** U S A. 4975, Aug 19 at 2355, tune-in one receiver here to 4976-LSB,
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)

** 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 .
This station has a “history” --- Powell near Silverstreet SC``

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
hours, group: La Mejor [sic: Peor?]. So this could be the unID SS I
had QRMing KWKH (Glenn Hauser, OK, WORLD OF RADIO 2100)
