The Desert Whooper

Since it's too late in the morning to hear this at home I checked it out on the KFS SE kiwi

4095.65 KHz  DW   S5 signal  BAT 14.0volts  oTMP  102deg  iTMP  110deg  PV  767 mAmps

I've been trying to catch it when the iTMP hits 120 as it did a year ago.

inside temp of the box hit 123 degrees at 1800 hrs PST!   

4095.65 KHz  DW   S6 signal  BAT 13.2volts  oTMP  109deg  iTMP  123deg  PV  203 mA

I just caught DW's internal temp sitting at 120 degrees

greetings from the DW team

All of your reports here have been read with great interest! We received a eQSL request from Italy! Quite the surprise.

A few months back we added a device to bleed off static charge from the antenna.

On October 27th we replaced the battery. Electrically it seemed healthy but it appears to have spit out some small amounts of acid from around the battery's terminals. With the shorter days the battery receives less charge so we want it to be in tip top shape.

Lately we've been kicking around ideas for wind measurement and it may be a new box but similar to DW

Hello, all...

I just received a nice eQSL for my reception of the Desert Whooper.

Thanks to the team!

A few thoughts based on the OP's description of DW.  I think the frequency would be 4095.700 KHz, centered on the CW signal, but not 4095.720KHz, centered in the middle of the whoops. The whoops start at .700 and sweep upwards. In warm weather the CW is at 4095.650

Thanks Jim, I had actually dialed up a bit to center on the CW and the whoops sweeping upwards from 4095.720. Probably time to recheck my calibration.

18.52 UTC CW transmit two letters "DW" and piiip piiip signal, SINPO - 35553, S3, listening via websdr KFS, California.
Please, send me eQSL, thanks

Looks as if the cloudy winter weather in the SouthWest is impacting solar charged beacons such as DW. This morning is the lowest battery reading I think I've ever seen in the three years it's been running.

Thanks very much  for eQSL card #22.
I like  your QSL!

DW was officially deployed to the Western desert on February 21, 2021.

Happy 3rd birthday!!

Great signal tonight, about 20dB over the local noise floor

Signal is a bit weak at home but is S7+ on the KFS-SE kiwi

It's hot out there!

Battery 13.0  outside temp is 107 and inside the box temp is 120!  PV was about 59

[Teotwaki]

It's hot but still alive. The heat has lowered the transmit frequency a bit.
