Hifer report with good news
Posted by Bill Hensel on September 02, 2015 at 01:19:35.

I did not go out in a remote area today but I should have. I should have fished today also.

Anyway, here is what I managed to noodle out of the ionosphere today not unlike catching a few trout on a fly in a stream with only a few small trout.

At 1557 Utc GNK faded up very strong for 5 or 6 or very strong IDs then faded out completely.
1607 Utc FRG was with weak fads ups
1616 - 1623 Utc NDB faded up five to 6 times
2026 utc I caught FRC and GNK with a few weak fad ups..

We are now in the scheduled shutdown of the FCC's interactive Web pages, due to upgrades. The Electronic Comments Filing System (ECFS) is one of those planned to be unavailable until next Tuesday morning. It will not be possible to file Reply comments during the outage, nor to search the ECFS for comments already posted in the LF/MF ham rulemaking proceeding.

Until the FCC page returns, LWCA has collected all 39 filings posted as of 6 PM EDT on 2 September in a repository at lwca.org/Docket15-99. You can select the one(s) you want to read in a new browser tab or window, or save any of them to your hard drive.

Wednesday & Thursday
Posted by John Davis on September 03, 2015 at 19:08:09.

Only had a relatively short session yesterday, with MP coming in at solar noon but then fading as the LF spectrum got a bit noisier with static. Not much at HF yesterday, either, except CODAR and this scene of EH and NC in collision. Both were strong enough to produce distinctive beat notes. Nobody else was audible or visible.

Got out to the field a couple of hours earlier this morning, and MP was going great. Solid copy on the QRSS30 screen as well as 60, and even a faint trace at QRSS3. Still watching, and hope to present a capture or two later today.

Checked HiFERs briefly before going to LF today. NC was audible and strongly visible, EH was visible, and CODAR of course. My first tune around the band yielded nothing but an outlaw sending long dashes and occasional random Morse-like keying around 13562. Tuning back lower, I then encountered WV for the first time in a couple of years! QSB resulted in some wide level fluctuations, but I was fortunate enough to catch one of the peaks and parked on the frequency to listen for a while.

Was listening on the farm around that time, but did not copy such a signal here. Quite strong ISM racket here centered around that spot, though.

Today's HiFERs thus far have mainly been NC and EH. Early this morning, I thought I had USC for a while but couldn't be sure under the heavy CODAR. At mid-morning, MTI finally returned to audibility after being absent for several days, I caught snippets of WV again, and just briefly I had what was probably V1RGO/B (bits of keying right at the noise level, then suddenly what I took to be a "/" followed by a definite "B"), but it faded away before I could get another shot at a complete ID and never returned.

I've heard those "pips" since March, 24 hrs/day in central Florida suggesting mine is of local origin, perhaps within a few miles of my house. Other listeners in the western USA also report them but with some slight differences in timing and signal strength. So, is there more than one source?

I count the 55th pip as a double pip, whereas others reported 57th pip as a double, usually at the 60 second mark.

Thanks to excellent propagation earlier this year, I've actually heard two transmissions, that is, two sets of pip signals a few Hz apart confirming more than one source.

Thus far, the intent of these signals is unknown.

Saturday evening at 7:45 pm EDT, I am able to copy for the first time WM. EH is always heard here.

In addition, I am copying another unknown "pips" signal on 13563.665 KHz. On full band spectral view, it looks like just a dit about every 0.8 seconds, but at 3 seconds/dot, it shows to be about 10 Hz wide, with skirts on either side. Not a beacon it seems.

at last i can finally attempt to offer something coherent to a discussion on the forum :-)

isn't that within the HF part 15 allocation? also didn't ups have an allocation down there for something in addition to there 220 MHz allocation?

could those signals be something to do with UPS?

This is indeed in the Part 15 ISM (industrial, scientific, medical) range. Most of the use is from dielectric heating, medical heating treatments and RFID. I can picture a conveyor belt with widgets going through a dielectric heater (big transmitter) getting zapped for short periods.

The equipment does radiate, and the range around 13560 kHz just screams with continuous and pulsed signals. By keeping our "Hifer" beacons at least a couple of kHz above or below that clump, we miss most of the stuff. But you will find such signals up and down the band.

The Hifer and the K index of 5 and G1 mino storm
Posted by Bill Hensel on September 07, 2015 at 16:47:12.

This morning from 1446 utc - 1450 utc GNK was coming into Pine very well...many ID s in a row and pretty strong. Then it went away and never came back.

Just goes to show Hifers pop up when condx seem that they would not. Kinda of like catching a trout in a location in a stream that it shouldn't not be at.

I think thats what makes hearing these little signals so much fun...

While on a short hike yesterday (Sept 6) into the Pike National forest FRC was heard on my KA1102.

Good observations, Bill. I'd like to be out in the field today myself, but we've got minor storms of the more earthly kind close enough that I'm reluctant to set up the buffer at the base of the antenna. Had a couple of close calls with lightning last summer from storms that popped up without notice.

Also, there is semiconductor manufacturing equipment that uses 13.56 MHz - CVD/sputtering chamber, for instance. A friend of mine related a story about a 10kW sputtering chamber with bad SWR - was scary for him!

So, yes, these things can radiate too.

 

73.25 kHz
Posted by Clive Carver on September 11, 2015 at 21:09:23.

Due to a network psu which supplies my SDR-IQ receiver fault, I have not been monitoring VLF or LF for the last few weeks.
 
Now back up and running, I have noticed the return of transmissions on 73.25 kHz which used to be MTO21 from Rugby many years ago. Then MTO21 was within the UK 73 kHz LF Band which existed 29th April 1996 to 30th June 2003 with a
1 watt ERP limit.
 
Looking at Peter DF3LP’s excellent Kiel Longwave Monitor at www.df3lp.de  I can see some low power testing on 24th August with H24 operation earlier this week.
 
At Hawarden, North Wales 53-11-44N 3-01-42W Signal strengths of 71.25 kHz  -36dB, MSF 60.0 kHz -32 dB, 51.95 kHz -44 dB, DCF77 77.5 kHz -52 dB and 81.0 kHz -24 dB.
 
Likely Tx sites for 73.25 kHz being Crimond, Inskip or Anthorn?

I did not listen long today however at 2121 Utc GNK was weak but full copy on a number of the IDs over a two minute listening time ( I wish it was a bit faster LOL), at 2123Utc FRN was top dog with a nice signal and once again little ole NDB faded up three times at 2126 Utc.

I hope to get a QSL card from the NDB operator...I would enjoy seeing what his set up looks like.

Not bad for me of late....I keep hoping to hear TON someday...
Poor little RQ hasn't been heard in quite a while.........

My ELF+VLF+LF reception hardware
Posted by Ben Hutchinson on September 20, 2015 at 02:53:51.

My equipment is actually quite simple. A laptop computer, and a long wire (about 20 feet) is all I am using. This picks up the electric field, not the magnetic field, even though (from what I've read online) most people use coil antennas for picking up the magnetic field when listening to signals in this range. My laptop has sound hardware that supports audio input via its microphone connector. This is better than a line-in connector as microphone inputs have a much higher gain amplifier, in anticipation of the much weaker signal coming from a microphone than would come from a line-level device. This extra gain is great for ELF, VLF, and LF listening, as no antenna of reasonable length is going to be very efficient for receiving signals in this frequency range, which have such extremely long wavelengths. So brute force gain is the only way to make up for that fact.

While the above mentioned mic-in port is not that uncommon among consumer level PCs. Something that is uncommon, that my laptop happens to have, is a 192kHz sample rate on the mic-in port. This allows one 2 theoretically capture up to 96kHz of audio, though I have discovered that due to my laptop's sound hardware's low pass filter on the mic-in port, I only can get up to about 50kHz before the signal strength drops very close to the noise floor. This is only 2kHz better than the 48kHz maximum permitted if I was using a 96kHz samplerate. However, even 2kHz more is better than 0kHz more, so I usually use the highest sample rate permitted by my laptop's sound hardware of 192kHz. Also, if I record at this sample rate, and then take the recorded file, and use software to highpass filter it above 50kHz, and then amplify the signal, I find that I can see signals up to about 70kHz on a spectrogram display (albeit, a lot of noise also becomes visible, so the SNR is much lower than in the lower part of the band, due to the computer's sound hardware's lowpass filter). And it can take a lot of amplification like this too, because of another great feature of my laptop's sound hardware. The mic-in port has a 24bit bit-depth. This means a lot of dynamic range, so it can take a whole lot of amplification, before the signal waveform starts to look "posterized".

What does this all mean? It means that not only can I use my laptop's sound hardware (without any additional radio equipment) to receive ELF (0 to 3kHz) and VLF (3kHz to 30kHz), but I can also use it to receive in the low end of the LF band (LF being from 30kHz to 300kHz). Normally if you want to even be able to think about receiving any part of the LF band, you need an external radio receiver, but my laptop's sound hardware is able to be used as an SDR, capturing the RF signal directly, and processing it later in software to extract specific parts of the signal, and it covers all of the ELF band, all of the VLF band, and the lowest few 10s of kHz of LF band.

My antenna is about 20 feet long, and is what is often called a "longwire antenna". It isn't cut for any specific wavelength. A short alligator clip wire (about 1.5 feet long) clips to one end of the antenna wire, and also to the center pin of the black RCA connector on a stereo audio cable. The audio cable has a stereo phono connector on one end, and a pair of RCA connectors on the other (the black one is left channel, and the red one is right channel). The stereo phono connector on this audio cable plugs into the mic-in port on my laptop computer.

Bill;
WOW, I am impressed! The propagation god was smiling on you for those receptions. Just proves big antennas, high power, and $x,000.00 receivers are not required.

I am curious about your location at the time of reception. I don't know for sure where you are located and would like better knowledge about my coverage. Also, I assume, but would like to confirm that you copied the CW ID. The beacon sends both QRSS FSKCW and regular CW.

Thanks for listening, and good DX.

BBC Radio 4 - demise of long wave technology
Posted by Mike Terry on September 26, 2015 at 08:00:28.


Daily Telegraph
26 September 2015
Excerpt:

After more than 90 years the days of the Shipping Forecast may be numbered due to the demise of long wave technology

It has kept sailors safe on the ocean waves for 90 years, becoming just as much a part of national consciousness as cricket, cups of tea and The Archers.

But the days of hearing the Shipping Forecast out on a boat may be numbered thanks to the demise of long wave technology, a veteran announcer has said.

Peter Jefferson, who read the Shipping Forecast to Radio 4 listeners for 40 years, said the "very old" transmitters which worked on long wave could soon be retired.

If that was to happen, he said, anyone more than 12 miles from the coastline would be unable to hear the shipping forecast on long wave, ending a Radio 4 tradition dating back to 1924.

Speaking at the Radio Times Festival, in Hampton Court, Mr Jefferson said the soothing tones of the Shipping Forecast would then be left to its many fans who choose to listen to it from their homes in lieu of a "sleeping pill".

....

He added: "The long wave will be retired because it's very old and costs a lot to maintain, I think it' days are numbered now."

....

The valves used in the transmission system, based at Droitwich in Worcestershire, are no longer made, with the BBC said to have once bought up the entire stock of 10 in the world in order to make it last as long as possible.

A spokesman for the BBC said they were no firm plans to end long wave broadcasting, and no date set for when the technology could run out.

The service currently reaches as far as south-east Iceland, and is occasionally picked up as far as 3,000 miles away.

The forecast, which airs four times a day, is currently listened to by a large audience on dry land, with the vast majority choosing to tune in for pleasure rather than professional necessity.

,,,,

Of his early days at Radio 4, (Jefferson) told an audience he had been tested by his older colleagues in a ritual prank, which saw them take his script away mid-broadcast and leave him to fend for himself.

His book, "And Now The Shipping Forecast", is out now.

My little sawtooth is on the air non-stop and seems to favor 13555.1025 Khz. If I park my receiver on 13554.50 KHz USB, I get a sawtooth signal frequency shift from 601 Hz to 604 Hz, hence 602.5 Hz the midpoint.

HiFER Report
Posted by John Davis on September 28, 2015 at 16:38:38.

Yesterday, I took a break from monitoring MP on LF (solid copy all afternoon and evening) and quickly looked at HF for a while in late afternoon. NC had drifted up into USC, EH was intermittent, and MTI was audible at times. Nobody else was seen or heard.

This morning has been much better. NC is still in collision with USC. No MTI or PBJ today, but WV is present about half the time. And, around 11 AM CDT, EH and MP (HF) are sometimes faintly visible, in competition for the same space. I had slight hopes of hearing FRC, but the steady carrier on 13565.0 is back.

Also this afternoon, plenty of USC and NC, some intermittent EH and MP, and WV just barely identifiable at times. MTI returned part of the time this afternoon, too.
