HF Beacons / Re: Is the Desert Whooper OK?
« on: April 26, 2024, 1518 UTC »
DW currently coming through on the KFS SDR at a 539, at 1515z. The bands have been in the doldrums recently, so this is an encouraging result. It's good to have this robust signal back. The telemetry makes it more appealing than the average beacon; to me, at least. The connection with data collection in connection with the migration of bighorn sheep is interesting too.

HF Beacons / Re: New Dasher Beacon! "KOK"

...................I must admit to being equal parts intrigued by this beacon, and miffed at the fact that it is operating in an amateur band. I'm both a licensed ham and a CW op, so I am not very happy about this beacon being where it is.

From the Forum's mission statement "We do not encourage any radio operations contrary to regulations. Always consult with the appropriate authorities if you have questions concerning what is permissible in your locale."

Having said that I have a question:

How is it that a "pirate" beacon operating on a non-ham frequency is non-miff-inducing as opposed to one operating in the ham band? LOL

Well, I'm a licensed ham, and an avid QRP'er. 3579KHz is a frequency of interest to some QRP'ers, due to the abundance of cheap crystals available for that frequency, so I would have thought that the reason for the "miff" factor is obvious! Although the unlicensed beacons outside the ham bands don't irk me in the same way, I have always wondered something about them, and that is whether the operators of such beacons go to any effort to attempt to ensure they are not operating on or near any frequencies of critical interest or importance to other, legitimate users of the spectrum.

For the record, I do enjoy listening out for these beacons, but have never seriously considered operating one of my own mainly because, as a licensed ham, there are ample opportunities for me to get my "RF-emitting jollies" by legal means.


Michael Hopkins would be proud:

(surely where Bill Meara got the Colorburst reference from. Mike Hopkins was great)

I've been an active ham for fifty three years. There's stuff happening on the bands that distresses me. This is not one of them.

This falls into the same category as the WSPR tranmitting  pico balloons which routinely fly around the world with no control operator sending telemetry and an ID .... it's kind of a victimless crime.   There's no way this signal is going to cause a serious headache for anyone.

I wasn't aware of Mike's writings about the Five Meter Liberation Army. This is great! I must read this soon. As you say, it is almost certainly where Bill got the idea for the CBLA from. I recently became enthused about the use of 3579 for QRP CW operations, and was a bit dismayed to find a beacon on the very same frequency I wanted to operate on. However, as CW bandwidths are so narrow, it's possible to use a nearby frequency with no QRM experienced from the beacon. This is something I will be able to get over quite easily, and it's certainly not keeping me up at night. Nevertheless, I'd prefer that they stay out of the ham bands, even though that seems inconsistent with my enjoyment of listening to the beacons that are operating in other people's bands.

By coincidence, I decided to take a listen on the colorburst frequency this evening and maybe call CQ, in a vain attempt to revive the activities of the CLA (Colorburst Liberation Army). I like to monitor my signals on the KPH and KFS online SDR's. On looking at the waterfall, I noticed the KOK beacon, close by, on 3579 KHz. I can hear it at home in the SF East Bay, at about a 5 by 2. It's about a 5 by 5 on both KPH and KFS (Point Reyes and Half Moon Bay).

Googled it, found a YouTube video of it, and then this sub-thread.

Colorburst Liberation Army!! LOL!

The Colorburst Liberation Army was a concept, if not started by Bill N2CQR, then much promoted by him in both the Soldersmoke Daily News blog, and the Soldersmoke podcast. The idea behind the name was to pay tribute to the armies of ham radio homebrewers who would liberate the colorburst crystals from the TV sets their neighbors put out on the curb, and put them to good use in homemade transmitters.

I must admit to being equal parts intrigued by this beacon, and miffed at the fact that it is operating in an amateur band. I'm both a licensed ham and a CW op, so I am not very happy about this beacon being where it is.

Yes, I have noticed it too.

Well, I was always under the impression that we don't get to hear many pirates here on the West Coast, but XFM is peaking S9 into the SF East Bay right now, on my Belka DX and 70 foot wire at 30-50 feet.

22 Meter Band HiFER Beacons / Re: TSN
« on: September 25, 2022, 1739 UTC »
TSN coming through nice and clear on 13555.98 at about S3 on the KFS SDR, at 1730z. I sure wish there was a brief pause each time, before it sends the callsign. To the uninitiated, it sounds more like SNT than TSN.

Not sure why someone would go to the trouble to put a beacon on the air and not provide any information about it.

Does kind of seem to defeat the point, doesn't it?

Oh, I don't know about that. I can see the appeal in putting a QRPp HiFER beacon on the air, with no publicity or fanfare at all, sitting back, and seeing whether anyone ever finds it. Sounds like fun, to be honest!

Thanks HQ180. Just heard Cry Baby very faintly on the NUT SDR, on 7956, at 1600z on 9-12-2022.

HF Beacons / Re: Madonna
« on: September 03, 2022, 0602 UTC »
So Madonna is/was a dasher beacon in the Inyo mountains area and sun only. The Marin Ditter is AC line powered in the attic of an apartment building

Thanks for that Teotwaki.

I have not been actively listening out for HF beacons for long, so cannot tell the difference between some of these "legacy" beacons by listening to them, otherwise I might recognize subtle differences in the speed of the ditting, or even the sound of the keying waveform. I heard what I think was Madonna during daylight hours so, by that metric, it could have been either beacon. However, the beacon I heard was on 4097.27, which is only 40hz from the frequency that MB reported Madonna as being on. For it to be the Marin Ditter, it would have had to have drifted 420Hz from it's earlier reported frequency. Though not impossible, it's quite a lot, for what I assume is a crystal-controlled oscillator - even if there's a fair amount of inductance and/or capacitance in series with the crystal (unless the frequency was altered by human intervention).

HF Beacons / Re: Madonna
« on: August 31, 2022, 2349 UTC »
I'm not sure. I just heard it on the KPH SDR, on 4097.27 again, just above the noise. I tried the second harmonic, at 8194.54, and it was coming through a bit stronger. The fact that the second harmonic was a bit stronger does make one wonder whether it is the Marin Ditter.

Do we know for a fact that Madonna is/was a distinctly different beacon, or was there always the possibility that it was simply the Marin Ditter?

The battery is about 22 months old but has done very well so far. It is oversized in terms of the Amp Hours needed and so is the solar panel.

That was a good design decision. Top marks, and thank you for giving us such a great signal to listen out for, even though I know that wasn't the primary intent!

PCO coming into the KPH SDR, barely copyable above an S3 band noise level RST 239, with wideband QRM/QRN across the whole HiFER band. 2330z (1630 PDT) on 8-31-2022. No other HiFERs copyable on the band though. PCO is a regular signal here.

HF Beacons / Madonna
« on: August 30, 2022, 0001 UTC »
I didn't see a thread for Madonna, so am starting a new one. I'm guessing it has been included in the posts that some of our members make when they post all their loggings for the day.

Madonna at 4097.27 ~240 dits/minute at 4:40pm PDT (2340z) on 8-29-2022 Copyable above the S1 band noise most of the time, though occasionally dips under.
Heard on the KFS SDR. Also on KPH, with a similar report.
