Big storms here over night but now that things are quieted down waterhole hifers NC, EH, and USC are coming in well as usual. Higher up on CW hifers MTI and FRC are doing well too.

As there is no good list of VLF-transmitters, I created a list of VLF-transmitters in the Wikipedia on https://en.wikipedia.org/wiki/List_of_VLF-transmitters . Please check this list and expand it, but do not forget coordinates.

'Night of Nights' Reminder
Posted by John Davis on July 11, 2014 at 00:28:13.
The maritime heritage stations still able to operate on 500 kHz and their working frequencies in the 400 kHz band (plus HF assignments) will be on for their annual commemoration Saturday evening. Our story at the lwca.org home page contains links to the operating details, and a last-minute correction as of this evening.

Friday evening HiFERs
Posted by John Davis on July 12, 2014 at 05:26:46.
In the hour before sunset, the watering hole presented me with USC, up to half a minute at a time of the SIW duo (slant mode most consistently recognizable), EH, what appears to be 7P (though no complete characters at any one cycle), and NC. Of this lot, EH was most consistent with a viewable if not terribly strong signal level, 7P was consistently just at the edge of readability, while NC and USC varied widely in level...sometimes not visible at all, and other times quite bright and clearly audible. They did not track together.
Tuning upward, MTI was audible much of the time and PBJ was visible most of the time I was watching. Keying of AJO was barely audible some of the time and inaudible the remainder, but the DAID pattern showed up nicely on Argo. Two big unmodulated carriers precluded hearing anything of SZX. GNK faded in and out a number of times. It seemed that FRC might be present at half an hour until susnet, but wasn't strong enough for positive ID.
Have since been monitoring WSPR on 630 meters, hoping to see something from Laurence in Alaska some time tonight, along with the usual suspects.

Night of Nights + VE7 CW Beacons
Posted by Steve McDonald on July 12, 2014 at 20:12:21.
As many of you are aware, tonight from 0001Z-0700Z (1701- midnight PDT) is
the annual 'Night of Nights' reactivation of many maritime CW MF stations
operating near the 630m band. With Canadian amateurs recently getting
472-479KHz operating privileges, VE7BDQ and myself will both be operating CW
beacons during the event.
VE7BDQ will transmit on 474.00KHz while VE7SL will be on 473.00KHz. Both
stations will be at the 100W level.
Reception reports of either station would be gratefully received and
confirmed by QSL if requested.
Hopefully the usual noisy summer conditions will not detere listener
activity.
I have more information on the 'Night of Nights' activity posted on my blog
if you are not aware of the event.

VE7SL BLOG - "Homebrewing and Operating Adventures From 2200m to Nanowaves": part 15 Medfer Skip
http://ve7sl.blogspot.ca/
Posted by Robert on July 17, 2014 at 14:46:07.
I'm curious if anyone is aware of any instances of part 15 medfer skip. if so what was the distance of the skip?
i seen this question asked in another forum and no one seemed to have an answer and i confess i am curious myself about the subject of part 15 medfer skip.
i'm assuming that there is just too much noise on the band for a traditional AM mode skip at 100mW input with an electrically short radiator to go any significant distance via skip but maybe possible with the QRSS beacons you all use.
i thought maybe the brain trust here might have an answer to this question.

In reply to part 15 Medfer Skip posted by Robert on July 17, 2014
Sure, Part 15 MF signals propagate via the ionosphere, if that's what you mean by "skip." While the AM Extended Band from 1610-1700 kHz was being cleared of its former radionavigation occupants about 20 years ago, and before broadcasters were allowed in there, MedFER activity was quite productive. On quiet enough nights, a few hundred miles was feasible DX in plain CW, as we didn't have QRSS back then.
About the best reception report I ever got was from KØLR in Minnesota, about 800 miles away from where I was located in Georgia at the time. Todd Roberts and I used to exchange messages over a little more than 200 miles; not strictly what you'd call a QSO because we'd each put up one message to run all night, since it sometimes took several repeats to get all the characters of the message, given the fading characteristics of the band. A few times I tried a heavily processed audio signal in DSB mode that Todd was able to recognize occasionally.
There haven't been any MedFER DX reports posted here in a long time now, and certainly none for plain CW. Sideband energy from 10 kW broadcast transmitters is just too much to overcome. Only one operator is thought to be on in QRSS3, and we're apparently down to only one other even attempting MedFERing at the present time. I'd be glad to see what could be done with QRSS10, but I expect it would need to be attempted in winter.

No problem, Robert. Sounds like one could indeed make an excellent 20 and 22 meter antenna that way...or even a halfwave vertical for 10 meters with a nice low takeoff angle, provided you have a tuner that could match the impedance.

Good day - M P 137780.5 ish is now radiating on the air again, after a

Any and all reports appreciated.
73 Like Winter in the middle of the Summer - " EAR " Reception

Hi all:
I set up to monitor "EAR" overnight, and was I ever surprised when I reviewed the captures.. It was almost like Winter propagation in the middle of Summer.. I posted the captures in the Longwave Community Forum .. Re: Lowfer MP 137780.5
http://lwca.org/community/YaBB.pl?num=1405872709
You will see the bright red signal between my 2 am till 5 am time period.. there are a few of the characters that I believe could have been close to audible.. According to the Spec Lab color scale I am using; the extreme bright red is approximately 15 dB above the baseline noise level .. I was asleep at the time, so I can only speculate. Without going back thru past captures of "EAR" to compare; I don't recall ever receiving J.B.'s signal this strong before. When the LWBC signal went away, he was completely in the clear with a Whopping Signal here in Friendsville, TN. - EM75xr.. QRZ states the distance between us is 568 miles ( 914 Km ).. This is an amazing signal, especially for Summertime.. Receiving setup is the same here: Kenwood TS450S, Dual 500 Hz Filters, Outboard 70 Hz Audio Filter, and using Spec Lab with 20 Hz Audio Filters..Using the 70 foot Hickory Nut "TREE-TENNA" and am still amazed at its performance.. No matching Transformers, just tapped it 12 feet AGL, and ran 80 feet of copper wire into the shack.. The only thing I am doing in the shack is using a Variable Inductor, in series with the feedline, to peak the Tree for best reception..
73 to all, and thanks for your time reading this..

Congratulations, Andy. Excellent work! Just goes to show summer doesn't necessarily end DX, as long as one can have a decent noise level once in a while.

MP at Mid-Afternoon
Posted by John Davis on July 20, 2014 at 20:47:29.
"With all receiver oscillators and sound card locked to GPS I'm reading 137799.590 +/- drift" (typo...intended: 137779.590)
At mid-afternoon, I definitely concur ... within the limits of Argo frequency resolution at QRSS30, anyway, and with nothing locked to anything. ;)
Really nice signal and low noise for the most part today--just a very occasional crackle to S9, but mostly below S2. It's even quieter at 630 meters thus far. Wish I'd been able to go to the field last night and try for the WSPR bunch and EAR.
Don't know why the lowfer@qth.net reflector has been so crabby today! It's been rejecting mail from my main account for a couple of days with a lame excuse, and now it says my first and second attempts to send this as a reply from my other account "looked like spam." Can't even write to the list administrator to ask what's going on! So, I'm posting here instead.
(Just imagine what life's going to be like when every single thing you do in the course of a day has to go through "the cloud!" Your Internet-enabled refrigerator stops working because some server about which you have no clue, located somewhere you've never heard of, contracted out and operated by someone you don't know, suddenly thinks you didn't pay for your smartphone service this month.

Mitch, thanks for firing up MP again. The frequency quote from Jay must have a typo in it. I assume he meant 137779.590 Hz, not 137799.590 +/- drift. I've been watching with an SDR-IQ whose clock is tied to GPS. Haven't checked the sound card rate for awhile but the attached capture indicates 13777.97 Hz and the drift seems to have settled away.
