Looks like a very useful program, Jim.
The font situation you encountered in posting can be overcome by using the <pre> and </pre> paired tags around the data to force a monospace font, as noted in our FAQ page.
I've retrofitted those tags in your post, although you may notice that it shrunk the typeface a bit compared to the non-monospace default font. That's a problem common to most modern browsers, unfortunately, whose developers seem to think monospacing is old-hat; but if you use the <pre></pre> pair when initially writing the post, the board will automatically assign style sheet parameters to compensate.

LowFER SIW is good copy in both QRSS30 and 60, WM is fair, and WH2XXP is a welcome surprise at 185.305 kHz.
There is more t-storm activity off the Atlantic coast than recent nights, keeping static levels up, so I'm skeptical of seeing TAG; but I'll keep watching the watering hole tonight anyway. Also seems to be a bit more PLC QRM than recent weeks, too, but none around 185.302 this evening.

XXP on 185.305 kHz. I've been using ARGO at QRSS60 to look for TAG and it doesn't tune up that high so last night I switched to QRSS30. Saw some traces that probably came from WH2XXP but nothing from TAG. I've only copied TAG IDs a few times this winter season. Meanwhile, lowfer KE has come in every time I looked. E-W propagation hasn't generally been very good, but still good enough to often copy DL7NN and VO1NA on 136 kHz. And NDBs from South America have often been coming through so N-S propagation has been good.

LCSC, NC, EH, USC (on top of SIW), and MTI at the watering hole; plus WV and NDB2, TON, possible visual trace of VAN, unmistakable bits of RF, good YSO and KAH, and faint ODX.
Reception has been impaired today by use of a different notebook computer at the farm, which gives me no option to use external battery power directly. Turns out, its AC adapter is noisy all the way to 22 meters...noisy enough to obscure everybody but Pat's two beacons and NC. Its internal battery gives limited run time, of course, and the screen illumination supply radiates faint but annoying carriers too. Sure hope I can find a suitable connector for external battery power soon!

Thanks for the followup, Garry. I'd been waiting to look for KE until I've had copy of TAG based on previous years' results, but I'm thinking perhaps that's not a good strategy this time.
Alas, even if TAG had been present last night, I might not have been able to discern it anyway. I'm using a different computer in the field now, due to having fried the old Acer -again- three weeks ago. (Even though I remembered to disconnect it from the deep cycle battery bank before performing battery maintenance this time, and didn't reconnect until afterward, somehow overvoltage from the charger still popped the input regulator chip just like it did three years ago. This time, I'm not sure if a cheap replacement will be available for the motherboard, the way it was before.)
The hopefully-temporary replacement machine is an HP model that's even older, and runs Windows Vista...sort of...and requires a size of power plug that I do not have any spares for. So, I had to improvise a bit and run its AC adapter all night, powered from my Westinghouse 600i battery pack/inverter. The inverter is delightfully quiet at 1750 meters, but the HP adapter is not! After extensive testing this morning, I found out that it was the source of those new PLC lines I reported last night. Those lines turn out to be strong enough to degrade reception of the weaker daytime groundwave signals from WM and SIW, which are much cleaner when I run the machine only from its internal battery. At HF, the adapter produces a continuous soft hiss that obliterates all but the strongest HiFER beacons.
Really bad timing to lose my computer at the start of prime LF listening season, with supply chain problems rampant everywhere.

This is troublesome. SZX is mounted in an unheated outdoor weather container at the antenna. The thought was as it got cooler SZX should shift in frequency away from SIW. Unfortunately, I have no way to adjust its frequencies as it is also pulling duty as a 20 meter WSPR transmitter as well. I may have to send the unit back down to Bill in Alabama to have him shift the frequency away from SIW. If I have that done, what would be a preferred frequency to use?

I have to trust K5MO that it's SZX. USC walks over SIW at my QTH, which is too close to see your beacon except during sporadic-E openings.
If Bill can raise it 15 Hz from wherever he finds it to be at this time, that would put it back between the two SIW's, with maybe enough margin to account for next summer's drift in the opposite direction.

Finally got a chance to listen yesterday, and there was SHO! Admittedly, it wasn't quite as pretty halfway across the continent as when it left Oregon, but over a few screensful, side by side, it was plain enough to ID in the early afternoon. The attached image is a composite of two captures to show a wider range of frequencies. A third instance was also running, tuned lower, but nobody showed up below MTI's frequency all afternoon. Times in the capture are CST.
The old, temporary computer I'm using right now isn't strong enough to run WSPR along with three instances of Argo (they even choked once in a while, all by themselves) so I didn't try. There were so many propagation gaps in every two minute window yesterday that it might not have done any good anyway. Plus, it appeared sometimes that the WSPR slots might have been starting and concluding a few seconds early, but that's hard to say for sure.

Midway through the day, and there has been some activity on 22m to report from PVC. TSN continues to be audible as the "watering hole" is monitored with Spectrum Lab and WSJTx. Also prominent is 7P.
So far there have been a few other traces corresponding to beacon frequencies, and snippets of NC and EH. The former don't provide quite enough clarity to ID directly, although the frequencies are indicative of SIW (both transmissions).

Nice signal this morning, ending 50 minutes before sunrise...a good conclusion to "Year of EAR II," the second consecutive year of captures in every calendar month. There was a higher lightning count than I would have liked, but the propagation was favorable for an hour at a time, then would diminish for roughly an equal interval. Not bad overall!

It was a noisy night here so not the greatest for looking for lowfers. Nonetheless, SJ showed up just after 0200Z drifting slowly up, then down, then taking an abrupt jump downward to settle at 185.3015 kHz, where it was steady through the night. At times SJ was potent but there was plenty of QSB where it dropped from sight. Nothing was seen of TAG, but WH2XXP came through during a near-sunrise peak on 185.305 kHz. WM was in fine too along with local SIW.

Is anybody hearing HiFer "WV". I had a leak in the housing box and had to remount the Circuits in another box. I had to replace the home brew tuner as the other one was damaged by the water leak. After repairing and replacing some cables, I mount everything in an Orange Plastic Ammo container attached to a 4 X 4 treated post 3 foot above the ground. I read a Post that the frequency is moving around and I can only assume the thin plastic of the Orange box is letting the contents temperature change.

I was talking with Ron, NI7J/WH2XND the other day and he passed along the news that he is QRT on LF/MF. The station has been dismantled and a dipole for HF is going up using the old XND tower. His signal has served as a dependable "receiver check" day in/day out for several years, first on 630M and then on 2200M. For many, he was the first station heard on LF.
On a personal note, I first met Ron 5 or 6 years ago after hearing his WSPR signal on 630M using a clip lead antenna on a newly completed receive converter. Imagine my surprise at that reception. I drove up to his QTH the next day, and over a BBQ lunch, he managed to fill all of my free time over the next couple years with LF/MF stuff. Our running joke is that I blame Ron for all this (100' tower, amps, RX loops, etc.), and he blames me. Spoiler alert, it's all Ron's fault.
Maybe in the future I'll persuade him to get back on, who knows? Then it really will be my fault.

ABBY audible at 1650 Z, first time in 2 months! As John noted about YSO (which eluded me this time), signals today don't always last very long, unfortunately.
Half hour before ABBY, I had TSN nicely audible above the watering hole for a few minutes, then gone. NC was stomping right on top of LCSC, then drifted a bit downward over the next half hour. EH tended to fade a lot, but was in a relatively good spot. 7P showed up later, usually only visible for one or two IDs at a time. And USC is no longer atop SIW, but has dropped a bit further down in frequency and is now right in the middle of RY.
Nobody else was seen or heard at the watering hole, but WV was visible at 13554.010, TON was faintly visible for a short while, RF was visible and sometimes audible, so was K6FRC, and finally KAH achieved audibility a few times.
During the noon hour CST, the band was down to only the Carolinians, sometimes bits of RY, and a little FRC.

Tuesday night was very productive at the 1750 m watering hole; st least for the first half of the evening. WM and SIW were doing fine already when SJ signed on, then TAG showed up faintly but never quite yielded a full ID.
WH2XXP was also present, but I didn't realize until after the other signals had begun to deteriorate that the screen in which it was visible wasn't being captured earlier. Attached is a second file (7deca33.jpg) showing one of its IDs later in the night.

Nature dashed my hopes for KE last night with t'storms off the Atlantic coast. The computer battery started fading away before the lightning static did, although I did start to see traces of RF at the right spot and with the right durations to be elements of a QRSS60 signal. Will try again tonight if conditions look any better.
If I should achieve results with KE before midnight, I might then turn my attention to JH, even though I don't have particularly high hopes, given the description of his new antenna.

Great Statistical Analysis Program!
I've had to use cygwin64 and grep to attached data and then figure out how to parse it down more so Excel could load just a portion and create graphs.
So far, I've been using your program to compare various other modes to WSPR over the same paths. Rather eye opening when you do.
My only issue with using the WSPR data, is that while I know the power gain and radiation pattern of my WSPR reference antenna (TX and RX), I don't know what it is at the other end of the ether.
So, question, Jim. Besides the bandwidth reference for all modes as being 2500 Hz, what do we do for antenna differences, which will affect SNR. Or does it matter in regards to your matter of number crunching? Just wondering.
It's really too bad (IMHO) that WSPR doesn't allow for an APRS type power, height, gain and directivity (PGHR) encoded packet. UIVIEW32 uses PGHR (when available) to draw circle plots around APRS stations on maps to see where they overlap (Venn diagrams, if you will).
Anyway, Jim, you've done a great job of programming something that can "chew" on enormous amounts of data and produced meaningful information, which is the very definition of "data processing"!

Even with the unsteady frequency, enough skinny FFT bins got filled enough to display enough characters in ARGO during the course of the evening Thursday here in SE Kansas. See attached file.
The lightning count was only about 1% of what it had been the night before, and only 0.3% of what it is tonight--even without taking into account that tonight's severe storms are (a) severe, and (b) right across the border in Missouri, rather than way out in the ocean.
Having had reasonable results with KE, I tried for JH the rest of the night, as I had outlined in the previous post. As I feared, John's antenna did not favor me with enough signal to see more than one possible "H" about 2:20 AM CST.

Hi Folks,
Weekend monitoring resumed today at PVC. TSN was heard through the noise, but other signals were feint. NC apeared in the Spectrum Lab traces, and around 22:40 UTC there was one solitary WSPR decode from SIW.
At the watering hole, some feint traces in Spectrum Lab, but nothing clear enough for an immediate, obvious ID.

Here's the odd grab of USC (250 mile path) I saw last night on 22M. This occurred coincident with the arrival of a very strong cold front in our areas (the same cold front that produced all the tornadoes in the midwest the previous day).
Could anyone explain the distortion of the signal?

Hi John. I see two things in your capture that could be taken as distortion.
The not-so-square waveform with its tilt and odd corners is a property of the transmitter itself, which Pat attributes to some change in the internal circuitry of the Epson chip since his previous version. If that's indeed the case, then it must have some servo-like function that attempts to keep the frequency more nearly constant with slow changes in source voltage...fine for overall stability, but not so good for modulation with slow FSK via changes in Vcc. If the chip is one that sees Pin 1 as Output Enable (TH, PH, or PC in the full part number) and not as inverted-Standby (ST, SH, or SP), then it might be preferable to simply key the chip for on/off QRSS.
The other thing I see that could be taken as distortion is the presence of a second signal. USC is on top of someone else again in the capture, probably SIW. Use of single-frequency QRSS would help reduce the risk of this as well.

Hi John,
I never considered this to be part of the transmitter itself, as I've never seen such a short haul signal on 22M, so I'm sure you're right, John. I'll know to look for this again if/when we have such short propagation. I'll have to watch for Pat's transmitter the next time we get a squall line like this too.
In any event, it was fun to see a new signal on 22M

You may get another chance Wednesday evening. A new storm system is setting up to develop just east of my QTH that could produce a very similar squall line over almost the same region, the way they're talking this morning.
It would be fascinating to know the exact geometry of the propagation...most particularly, the direction of arrival of the USC signal. Was the storm between the two of you at the time of the reception, or was it still to your west or northwest?
It might also be worthwhile to monitor late today and early in the morning due to the Geminid meteor shower that is currently underway and peaks tonight. I would not expect to experience meteor trail reflection, such as happens at VHF; but since E-layer propagation depends in part on the availability of free ionized metallic atoms, it's conceivable that a decent meteor shower could help seed formation of sporadic-E clouds if the other necessary conditions were present. On the other hand, I think the comet/asteroid Phaeton, which is the origin of the Geminid stream, is considered a rocky body. So, I don't know how much metal its meteorites actually disperse into the upper atmosphere. It could be an interesting experiment in any case.

We are planning to carry our some test transmission on Dec 23rd, approximately between 12:00 UTC and 15:00 UTC.
The test transmissions on 23 December may present a good opportunity for listeners also, despite their shorter durations and more random nature, depending on the timing of weather events in the Americas. Since VLF is less impacted by diurnal variations than LF is, the signal should remain near nighttime levels, but static from overnight storms usually diminishes in the early daylight hours. This could be just the advantage some listeners will need.

Hi John,
To the best of my recollection (and I'll take notes next time) the front was between USC and my location. Due to the characteristic NE-wardly tilt of most storm fronts here, it was probably quite close to both of us (50-70 miles) at the time of the grab (I'm NE of USC).
I'll run the grabber all day long as usual and see what happens with the next front. It would be fun to see USC appear again.

You will be able to hear the mechanical 200 kW transmitter starting up at 07:30 UTC, and sending a CW message at 19:00 UTC on Christmas Eve. Also on air will be SK6SAQ on 3535kHz, 7035kHz and 14035 kHz CW, and on 3755 kHz and 7140 kHz SSB. Reception of the VLF signal requires either an up-converter for an HF receiver, or a simple longwire into the microphone socket of a pc, laptop or phone. The signal can then be heard and seen with the help of the very simple to use software made available by the Grimeton Crew.

You were hearing things--real ones--but probably not the same beacon that John K5MO was describing. The EH beacon is widely seen on slow waterfall displays, more than heard, because it uses narrow (≤10 Hz) frequency shift keying and a 3 second dot length. It wanders, but has never been noted that high up in frequency.
Instead, you were probably hearing intermittent pulsed emissions from unknown sources often found between 13557 and 13558 kHz. Some of them repeat single short pulses (like an E), some double (I), and some in groups of four (H). It's hard to say whether these are industrial equipment of some sort, or experimenters using rather slack gear (there's often audible frequency shift during key-down, manifesting as a chirp or in more extreme cases, sometimes even a whooping sound; and often a frequency drift from one transmission to the next), and/or whether it's even the same signal sources being reported in different parts of the country. That is something that might be discoverable by someone using multiple Internet SDRs in different locations simultaneously, or one local radio and one from the Web.

The watering hole was lit pretty brightly here in Kansas this weekend. On the night of the 24th, WM, SJ, and WH2XXP were solid at various times of the evening, bits and pieces of TAG showed up, and there were fragments of the seasonal visitor HO.
I'm given to understand something happened to WM later in the night, though, and it was conspicuously absent Sunday night. However, SIW and SJ were bright most of the evening, part of the XXP ID was clear, and there were fragments of TAG beside the glare of SJ but sometimes beneath a new spur of QRM from an unknown source.

Thanks JB. If you're referring to Marconi greeting us in Morse on the LW Home Page, I put that up on the 24th and will be taking it down on the 26th...but anybody who missed it can check it out here for a while longer:

No luck with DJI here in Kansas. Guess I wasn't looking high enough. Any timetable for nudging it down into the band, Ian?
KAH continues to be quite regular, though.

Lee, sounds like you want to purchase a filter so you may or may not be interested in this... thought I'd mention it anyway:
http://www.w1tag.com/518%20Filter.htm
I built this filter and I'm really pleased with it. I had a lot of junk box caps, so that helped cut down my cost. You may not have a good supply on hand, so I understand if you would rather purchase one.

Thanks for the report on KAH John. You can tell how cold it is on Georgian Bay by the frequency. Let me know what frequency you are measuring from time to time this winter please. I am leaving DJI unattended at the home QTH for the winter as I leave for Florida today. I did spend a couple of hours trying to QSY below 13.567 but without luck. I tried a wide range of capacitors to pull the crystal, but most of them put me higher, not lower. I need a new crystal, which I will obtain prior to my return in April. Best I can tell, I am still slightly above 567. Fortunately that is still legal in Canada. I am amazed that DJI has been heard so quickly as the antenna is a dipole, is low to the ground and is surrounded by hills. 73 Ian

You are correct. I don’t want to build one. I have seen this W1TAG site. Good information. My goal is always try to buy one off the shelf. Thanxs.

Thanks very much. I will look into both companies. In the mean time I remembered that I own a L-202 LF preamp. That has a built in low pass filter cutting off at 500 khz. Only 40db of attenuation but a good place to start.

The 40db attenuation might just be all you need.
Poland - 225 kHz
Posted by Mike Terry on December 29, 2021 at 14:10:12.
225 kHz Longwave radio broadcasting is becoming an exotic affair.
Those who remained can be counted on one hand. Let’s talk about Poland. Probably the loudest station in the range. Frequency 225 kHz …
Back in 1974, near the small village of Gombin, a miracle was built – the Warsaw radio mast. Antenna mast with a height of 646 meters. More than half a kilometer into the sky. The need to build this facility was the fact that the long-wave transmitter in the village of Raszyn, which was operating at that time, did not provide the necessary coverage for Poland. The new location was specially chosen: the central location relative to the Polish territory, high electrical conductivity of the soil.Until 1991 – the tallest building in the world. The mast worked as a half-wave emitter. Power 2000 kW.
General characteristics:
Weight: Polish sources claim 420 tons
Height: 646.38 meters (2120.67 feet)
Frequency: 227 kHz (before February 1988), 225 kHz (after February 1988)
Type: Steel lattice mast with guy wires.
On August 8, 1991, the guy wires were repaired. As the workers secured the temporary cables, a sudden blowing wind twisted the mast and it bent about halfway up. After the destruction of the mast, transmissions at a frequency of 225 kHz continued from the old transmitter in the village of Rashin.
However, the facility was used to broadcast the second program of Polish Radio at 198kHz. To work at two frequencies at once, the transmitter in the village of Rashin could not, and transmissions at a frequency of 198 kHz were stopped before the launch of a new transmitting facility.
In 1995, the Polish authorities began work on the renovation of the Warsaw Mast, as the importance of long-wave transmissions remained relevant.
But local residents opposed the restoration, fearing the danger of electro-magnetic radiation. The search for a new location for the transmitting facility has been started.
A new location was found at a former military facility near the town of Solec Kujawski. It is worth noting that local residents there initially resisted construction as well. The tension was eased after a large donation from Polish Radio for the development of the local community.
The programs from the new facility were broadcast on September 4, 1999. The masts are 330 and 289 meters high.
To this day, the broadcasts of the First Polish Radio Program can be heard at a frequency of 225 kHz. Power: 1200 / 700 kW.

SHO/KG7BZ Copy

SHO/KG7BZ,
Your WSPR and QRSS signals have been a fairly strong at this location today although with long and short periods of QSB.
Copy was good from 1820Z until 2355Z. Even when no WSPR decode was possible, both WSPR and CW waveforms were visible on the spectrograph.
I've ID your signal in the past and suspect propagation between your location and this is a product of Es rather than sky-wave.
