Title: New whooper beacon on 4095.65
Post by: Teotwaki on November 16, 2020, 2117 UTC
Sends the sweeping signal"Whoops" 15 times then CW ID's with the letters "DW". Maybe a "Desert Whooper"?

Weak with some fading on the KFS Kiwi SDR using the SE antenna.

No sign of DW here, and I was looking about the time you posted.  I do, however, see, the assumed new 4097.2 beacon (2 sec on, 2 sec off) fading in and out.

DW was weak and faded in and out of the KFS Kiwi SE receiver. Not a great signal. I think I saw the new dasher (4097.2) and it seemed pretty strong.

What's the story on the dasher? If there were any forum messages I must have missed them.

Post by: Token on November 17, 2020, 2225 UTC
No real idea about the new dasher, other than I first saw it about a week ago.  At times it is very strong here, other times unheard at all.  It seems that I hear it best about an hour after local sunrise.  At first I thought it was night time only (I did not see it in daylight for the first few days in a row), and that it might be related to the other new dasher on 7999.2 kHz (they have the same or very similar cycle times), and thought maybe shifting daytime/night time freqs.  But then I saw the 4097.2 during the day, and have seen it pretty much every day since.  However, I have not yet seen 4097.2 and 7999.2 at the same time, so they still could be related.

I love finding these kinds of signals! If you make a recording of the DW Whooper, please post a link here. I like to share these kinds of signals with my Twitter followers, who all love theses as much as I do. Thanks!

P.S. I tried to locate the signal myself at 4095.6 kHz via Token's WebSDR at approximately 1830 UTC, with no luck.

Glad you could hear DW on the KFS SDR. BTW I saw your Twitter posts and this new beacon is unrelated to Stephen McGreevyís ďinyo whooperĒ. He has written some long posts here and said he is quitting beacons altogether. His beacons never had CW idís and his whooper has been off the air for quite a while.

Welcome to HF Underground!!

What is your setup (antenna & radio) for receiving DW there in Arkansas?  I have been using the KFS KiwiSDR for now as my home antenna farm is still under reconstruction.

Token has posted a YouTube video of receiving the DW Whooper at his home along with a detailed description of the beacon's characteristics.   https://youtu.be/LEKZDaD7J8g

 "This is a pirate beacon, probably located in the US desert south west.  Some of these beacons have names, either given by the person who built / place the beacon or given by listeners who monitor the beacons, this one, at this time, is being called the "Desert Whooper", for obvious reasons.  The chirps have a distinctive, and one assume intentional, non-linear chirp, or "whoop", and the CW ID is "DW".  This beacon was first reported on the associated forums on HFUnderground in November, 2020.  It is assumed that it started operations about the same time.

The frequency of this beacon is 4095.6 kHz, and it consists of a series of chirpy CW dashes, or short, frequency chirping, duration carriers.  Each dash shifts downwards in frequency by about 600 Hz from start to stop.  A "cycle" for this beacon has a CW ID consisting of the letters "DW", followed by 22 chirping dashes, the first dash after the CW ID is slightly longer than the other dashes.  As far as I know, whoever placed this beacon has not yet released any details of its hardware.

Two other pirate beacons are seen in this video, a new and as yet unnamed beacon on 4097.2 kHz consisting of 2 second long flat chirps, and the long active Windy beacon in a failed mode.

Recorded at my location in the Mojave Desert of California, USA, on 26 November, 2020, 2353 UTC."

Post by: DYGradio on November 29, 2020, 0431 UTC
Thanks Token, great information as always and much appreciated! DW is fading in and out here. I am not seeing any of the other usual suspects in this range right now such as Windy, the 4097.2 long dasher, or the 4094 dasher. I can usually see one or two of the others at the same time as DW but that is not the case right now, whatever that might say about propagation from other unknown locations if those beacons are transmitting. 04:28 UTC 29 NOV 2020.

Post by: Teotwaki on November 30, 2020, 1530 UTC
The DW Whooper changed it's "whoop".  ;D

It now sweeps low to high with the very first whoop going from 4095.65 to 4096.35 and the next 21 whoops from 4095.65 to 4096.25 KHz. The sweep is a bit more linear and no longer has that "fishhook" look.


The CW ID of "DW" is still at the low end at 4095.65

Yeah, I noticed that.  I grabbed some SDR recordings of it right after it changed and will do a new video sometime this week.  I also noticed the ID has a small whoop on the entirety of the letter D that was not present before.

Post by: Teotwaki on December 03, 2020, 0355 UTC

Coming in S3 on the KFS Kiwi SE radio. The format of the beacon is now back as I reported yesterday. It was interesting that it sent the numbers "12.7" for a little while.

DW still sweeps low to high with the very first whoop going from 4095.65 to 4096.20 and the next 21 whoops from 4095.65 to 4096.1 KHz. The CW ID of "DW" is still at the low end at 4095.65 but no longer has that chirp on the first dash.

The format is a bit different today. Five cycles of "DW" and 32 whoops.  Then "DATA" sent 5 times in a row (no whoops), then "12.8" or "12.7" sent. About 4 minutes for a complete cycle

DW is still following this latest format. I've copied a peak of 13.0 (assuming volts) at times during the day today.

Since it went to this new format it has been very weak here at the house.  I can, sometimes, see it and hear it, but just right at and in and out of the noise floor.

Title: Re: New whooper beacon on 4095.6
Post by: Teotwaki on December 06, 2020, 0605 UTC
Roughly the same format but with interesting changes: 5 sets of ID & whoops, "DATA" sent 5 times in a row then one set of numbers/telemetry (?)  The overall cycle is still about 4 minutes with 33 seconds between "DW" in the set of 5.

Each whoop still sweeps from low to high
At times, two different whoop rates heard between CW IDs.
The "Fast" whoop is about 31 whoops between CW IDs and "Slow" is 18 whoops; not quite 2:1
The first whoop is now exactly the same duration as all of them, about a 200 Hz upward sweep
The CW ID of "DW" is still at the low end of the signal, about 4095.65
"Voltage" readout/numbers/telemetry that varies between 12.7 and 13.0

Switched from slow to fast whoop about 6:50 AM
Whoops all have the same duration.
Time between DW IDs is about 63 seconds with about 63 whoops

Then it sent 12.7 VLTS and 0.0 TMP
Overall a cycle is about 7 minutes

Really nice that you have a lot big enough for the 80 meter dipole!  Had to lookup DM12 to see it was a ham radio contesting/station locating reference https://en.wikipedia.org/wiki/Maidenhead_Locator_System
https://www.karhukoti.com/maidenhead-grid-square-locator/?grid=dm12  DM12 is around San Diego County, it seems. I think I did this once before but forgot where you were located as Maidenhead locators is not something I use. Definitely an interesting location shorthand.

Slightly OT: the ham WSPR beacons include Maidenhead locators with every transmission, along with the callsign and transmitter power in dBm. WSPR is a slightly magic protocol developed by Joe Taylor that can decode well below the noise floor, but for obvious reasons may not be suitable for pirate beacons!

I had read a bit more on it too and it's really very ham specific and am not sure if many SWL hobbyists outside of ham radio use it.

PV....PhotoVoltaic?

Hours of sun, or....

Hmmmmm....

"PV" as referring to photovoltaic works for me.  8)  Hours of sun is interesting but how would it be used as a telemetered metric? The calculated hours of daylight numbers are available in lots of websites. If there was partial sun available (light clouds?) how could we communicate that via CW and then use the information to ascertain the beacon's health?

Offgrid systems are all about AmpHours (AH) into the batteries and AmpHours out.  Measuring PV current across the hours of daylight can give a sense of AH if you know the solar panel is averaging 18 volts into the charge controller. If the beacon's current consumption has been measured in the build phase that would provide a baseline for when it has been deployed. I don't know how monitor and log AH with a microcontroller in a beacon and then transmitting it via CW :-\ Interesting problem though. Look at Windy with it's minimalist telemetry crying out for help but the owner has not driven out there and installed a new battery. :o

Couldn't check DW on the Kiwi southeast array; someone's has had it tied up for a while. I try to get in, listen and get out to free it up for the next listener. Anyhow the omni is receiving DW pretty well at S3

A strong signal tonight with little fading. The format changed/evolved a little. In the past it sent "DATA DATA" before sending the telemetry. Now it gives 5 slow (1/3 rate?) "whoops, pauses and then starts off with the BAT, then TMP and last of all it sends the PV numbers.

Catching a few "whoops" fading up and down here this evening, signal too far down in the noise to copy any telemetry. A bit stronger on the horizontal long wire as compared to the vertical, I can make out the "DW" ID but not much else. I believe I caught the TMP at 55. 02:45 UTC 10 JAN 2021

DW has become the "channel marker" for this slice of spectrum . While Windy is usually able to be found (in it's S , H or original full featured version) The Whooper is a real stalwart.

Format has been tweaked a little. The PV telemetry seems to have been switched from X.X Amps to xxxx mA. No longer uses a decimal point and leading zeros are dropped. So 400 mA is never sent 0400 but 2 Amps can be sent 2000

I also count seven "DW" markers, six sets of 30 whoops and one set of 5 slow whoops before telemetry in the sequence.

Which antenna/receiver combination did you use?

I've been trying out a number of kiwi SDRs and hear some things at one but not another so it's fun to see what works where. BTW, on the HFUnderpants kiwi family, can the frequency markers be updated easily? I still see "Haystack" and "Viking" but those are long gone.

Was up at 6am PST to look for beacons. At first I did not hear DW on my home receivers so checked the Western SDRs. Heard it really well on Utah and Sedona. KFS was a bit noisy but signal was there. Telemetry said the battery was at 12.8 but 0 for PV.  Temps were 49/56. Then around 6:25 I heard the whoops rise up out of the noise on my home receivers as the sun rose in the east. The PV reading gradually went from 0 to 11 so if it is a solar panel current reading it should rise sharply in full sun.

DW has been noticeably stronger here in the past week or so than ever before. Prior to this I was never able to get much of a usable copy on it but the early evenings especially now it has been blasting in. It is fading on me now to the point I cannot copy the telemetry but I am checking in on it quite a bit later in the evening than I usually do.

Weak but audible on my 900 ft sky loop antenna as well at 1031 UTC 15 Mar 2021. Actually the signal is starting to come up a bit now. Still dark here due to the change to DST, often reception peaks right around sunrise, perhaps a greyline effect?

The three digit PV numbers are puzzling!

Hi Syfr!

I've been logging the telemetry from DW for a while now and here is what I have observed.

Most of the day the BAT reading sits at 13.7 with the PV reading a single 4 which is about what a typical PV controller might consume in milliamps while not charging the battery. Once in a while I will catch a three to 4 digit reading as if the charge controller is topping off the battery. Somewhere after 3 PM the BAT reading ramps up to 14.3 (equalization volts) and the PV reading is in the 400 to 600 range. After sunset the BAT reading slowly declines until it hits 12.8 prior to sunrise. During that time the PV reading is 0 although once in a while it reports a 1 (A2D noise I guess). Around sunrise (06:30-ish) the PV reading starts at a couple of digits and as it ramps up so does the BAT reading. Around 07:45 I see the PV reading peak in the 1100 to 1200 range. Within an hour after that it is reading 4 or 5 with the BAT reading sitting at 13.7 or 13.8. Am guessing a couple of amp hours were sent back into the battery so the panel and battery are not small.

I'm convinced PV is reading out in milliamps and correlates well with the BAT readings.

I noticed listening last night that the last whoop before telemetry is now more of a long dit than the normal whoop.  Was that just an anomaly of yesterday?

I believe it has always been about 2/3 of an upward sweeping whoop. Am guessing it is just a matter of timing as to when the microcontroller decides it needs to send Morse Code rather than analog whoops.

Thanks for sharing your observations on the PV telemetry.  I normally don't listen early in the morning as I have the opportunity to  this week, and the sun availability vs PV number correlates well to what you describe. 

I've noticed also, that the battery is pretty stout (especially given the duty cycle of the transmitter) and its recovery time is short, which supports your observation on the capacity of both. It's a well designed system and hopefully will be with us a good long time.

Wish we could send out the Geek Squad to service Windy.

  I had never noticed that last slash before telemetry as being truncated as I heard it yesterday. Perhaps the AGC of whatever radio I was using further shortened it to the "dit" I heard

Listened to DW last nite and could hear it inside on the whip  antenna on the portable. Really impressive performance for a very marginal receiver.

Windy appears here earlier and disappears earlier than the whooper.

PV could be solar irradiance in watts per square meter.  That tends to range from 0 - 1200 or so.  Maybe someone already brought that up.

Thanks for the SDR link!

If the PV reading was irradiance I would think it would continuously report a large positive value during daylight hours regardless of the BAT reading.

What I have observed over the months is PV readings rising in the morning after dawn with a matching rise in BAT numbers up into the low 14ís. After a couple of hours BAT has settled at 13.7 and PV drops to 4 or 5 which could be the idle current of a PWM solar charge controller circuit.

Later in the afternoon the BAT and PV readings rise again as if a lead acid battery is being topped off.

I recall Syfr raised the idea of irradiance before but if I wanted to know battery health Iíd measure voltage and current and if possible calculate amp hours in and out of the battery.

Fun stuff!!

I just spent the evening trying several Kiwi SDR's around the continent. Groundwave strength all over AB and northern BC, but unreadable in AK. Barely a whisper east of CA, but heard in CA and unreadable in HI, WA and OR. Pretty good in NV.

Seems to currently be following the 4MHz HAP chart line centred on Vancouver going N-S.

Anyone know of a Mexican SDR that isn't listed?

Sure! Itís here at my place in Wrightwood, CA at 6275í ASL and Iíve had it working for about a year, but just put it online for the world a few weeks ago. Itís a KiwiSDR with a home brew 5v linear power supply. Antenna is a W6LVP active loop on a speaker stand in my backyard, fed with about 25 feet of RG-6.

Relatively rural area, but houses are close together so there is some domestic RFI. I donít seem to hear much above 15MHz - not sure if thatís the antenna, recent propagation, and/or being tucked up against a mountain. At some point I will put some wire up in the trees and see how those compare. But it seems to work great for MW and pretty well for the lower HF bands.

I used to live on a few acres and had bigger wire antennas (plus a vertical I transmitted with) and used my Perseus to listen. This setup now isnít quite as good, but for the space I have, itís acceptable.

Thanks for your interest and enjoy the SDR!

Nothing electronic likes that kind of heat....especially things like electrolytic caps .  It must see direct sun at times.

Based on DW's telemetry data and assuming the temps are Outside and Inside, the data shows a delta of 5-8 degrees typical. Therefore I don't think there is much in the way of direct sunlight impinging on DW's box. I believe the delta to be the product of internal heating due to power consumption. Conventional electronic components are designed to operate with upper limits generally set at 158 F for commercial applications. Good electrolytic caps are typically rated at 25,000 hours service life at 70C/158F. Chinese quality can be a crapshoot but I have to say I have had some Baofeng UV5R's in 24/7 use for three years without failure.

DW has been back on the scene about two weeks and the signal has been pretty consistent. Right now (0404Z 13Aug2021) I have it at +20-25 dB above the local noise floor shown by the KX3/PX3.  DW's BAT readings seem good where the morning reading of 12.9 indicates a battery at 100% charge after running all night.

I have a crummy antenna at home, though hope to listen for DW on a camping trip to the Eastern side of CA in a few weeks. In the meantime, I just had a listen on several online SDR's, and was excited to hear it over a wide area. In the period from about 0442 - 0446z on 9/15/2021, I heard it on Kiwi SDR's in the following locations -

Prescott Valley, AZ at Q5 with an S5 noise level.
Missoula, MT at Q5 with an S4 noise level.
Truth or Consequences, NM at Q1-Q2 with an S4 noise level (can hear whoops, but not copy telemetry).
Fort Collins, CO at Q1-Q2 with an S5 noise level (can hear whoops, but not copy telemetry).
and of course the following two -
Half Moon Bay, CA KFS at S7 with an S4 noise level (Q5 of course).
Point Reyes, CA KPH at S8 with an S4 noise level (Q5 of course).

Oh, and at 0503z, I could *just* hear the whooping under an S5 noise level from a Kiwi SDR in Booth Bay, British Columbia.

Yes, the Desert Whooper really gets out! It puts in a respectable signal here out east in the morning just before sunrise.

All of the reception reports are very much appreciated and are a bit exciting too! This is the first HF telemetry beacon built by the DW team and the temperature reporting has filled a gap in our remote location weather data used for evaluating bighorn sheep migration patterns. Some of the government weather stations in the general area have been proven to be unreliable so we decided to build a weather station of our own.

Development started around September of 2010 utilizing a shortened antenna for local reception in our  city.  It was quite a surprise to read that the KFS SDR's still heard the beacon! That was unknown by us until reading of it here. As reported here on HFU, the whoop pattern and telemetry evolved over the months but were finalized early this year so as to commence with the beacon's final construction and testing. The beacon's on site installation turned out to be quite a challenge too, including backpacking the hardware to the site and reducing the visual signature of the equipment.

The transmitter's "whoop" was engineered to provide a distinctive yet consistent pattern that could worm through noise and interference yet fit within CW bandwidth filters. It also provides a sense of time between telemetry reports.

A reliability issue with the final amplifier was resolved with a redesign and retrofit. The 2N3866 bipolar transistor was replaced with a more robust IRF510 MOSFET that is not fazed by the 120 degree internal temperature peaks. The transmitter circuit has a jumper set up to allow bypassing the MOSFET for a final  output of only 200 mW. The MOSFET is slightly less efficient but the battery and solar panel are sized to provide at least three days of run time in heavily overcast weather so there is little impact from reduced efficiency..  The BAT and PV telemetry show the battery should provide a long life before requiring replacement. Hopefully the beacon continues to run well in the winter months.

The antenna system was a challenge to engineer but has exceeded all expectations as proven by the reports that all of you have generously supplied. Despite primarily aiming for NVIS operation over the area of interest the broader coverage across North America is turning out to be very beneficial due to the broad public network of HF SDRs.

Great catch at home, especially with Denver's urban noise infesting local airwaves! I have a bunch of Grid-Tie solar systems around that kill my chance at long distance catches.

In the first page of this thread there is a post with an email address for DW eQSLs.

First time hearing the Whooper this morning under a tremendous noise level.
Could hear the Whooper but copy wasn't good enough to copy the data string.

Sept 17th, 11:27 UTC, 4095.65.

To hear it from your location is quite an achievement.

Thanks Dave, but I think it's more of a testament to the Whooper's antenna system which I'd love to hear more about!  8) 8)

This thread was started when I discovered DW last year and logged numerous reception reports.

To learn about the antenna you want to see the thread from the people that built DW    :)

Propagation has been changing quite a bit. A few times DW's signal has been noisy even into the mighty KFS kiwi SDRs.

It's been about 11 months since DW's signal went "big" in February of 2021. The frequency has "aged" upwards about 50 Hz. In the last few weeks it has become easier to hear over more hours at home.

I can hear DW on both of my receivers at home, Sedona Kiwi. Northern Utah Kiwi, all four KFS Kiwis.

BAT     13.7
O TMP  59
I TMP   50
PV       1958 (mA?)  This value steadily rose from a couple digits at 7:15 AM and BAT reading rose at the same time

I've been wanting to compare readings with my original posts from a year ago

BAT     13.8 
O TMP  45
I TMP   53

Likewise am easily hearing DW at home and on the same kiwis so signal strength appears to have held steady

good copy here at home. During the shorter days of the year Iíve seen the battery go as low as 12.6 volts in the hours before dawn. With the longer days Iím seeing 12.8 in the early hours, much the same as when DW was deployed a year ago. Also the outdoor temperature readings seems more stable and when the air is really cold there is a much larger delta from the iTMP readings
