DGPS / Re: DGPS Loggings Night of 27 Nov 2016

What's a little frustrating about this & NAVTEX (where I've also heard way out west), is that I have yet to pull in a west coast MW broadcaster. Can try to use the DGPS reception as a hint as when to try for the broadcasters.

Pretty good that you got several from the west coast.

That would be odd, as the first 3 or so minutes decode fine. I started the recording hours earlier, and Perseus makes 80 min (~3.5 GB) files, and this is file #8 with no intervention.

What is the format for the Perseus files? I might take a peek inside and see what its up to.

Unless... at that time, my system found a new NTP peer and it was off, which would've been weird.

Ran it again with Max zCount still set to 6 and it behaved the same. Set it to 999999 and now its decoding. Did get it to decode around 20, but seemed as not as many as when at 99999, but more than 6.

The time on the PC should've been accurate as there is a time sync program on there (from Meinberg, not using the stupid & useless m$ joke of a time sync thing).

Is there something I can check in the I/Q file to see what's its problem is?

MW Loggings / Re: French-language 940 station=? November 27, 0500 UTC

You found a shiny new station in Montréal: CFNV


From Glenn Hauser:

http://www.worldofradio.com/dxlatest.txt

** CANADA. CFNV, 940, Montréal testing --- CFNV 940 in Montréal QC is
now testing with music and test message in French. Will be French talk
at 50 kW. Curious if you fellows can catch the test after dark (Charly
Gauthier, Brossard, QC, 1943 UT Nov 16, WTFDA mwdx gg via DXLD)

From another site:

TTP Media’s CFNV 940 AM begins on-air testing.
After occasional sputters of an audible tone a few hours a day over a few weeks, 940 AM has actual audio for the first time in almost seven years as TTP Media’s first AM radio station has officially begun testing.
The programming consists of music in English and French, with a 23-second announcement about the station about every 15 minutes confirming its callsign of CFNV and asking people with reception issues to call 1-855-732-5940. It says the station will launch “progressivement sous peu” or “très bientôt” (the message varies slightly).
CFNV will be a French-language talk station when it launches, which the CRTC has said it must do by Nov. 21. The licence was first authorized in 2011, and the deadline extended three times (one more than usual).
The deadline to launch an English station at 600 AM passed on Nov. 9. The CRTC confirms to me it has received an application for an extension to that deadline (which was supposed to be final) but has not made a decision yet.
A third station, a French sports-talk at 850 AM, had its authorization expire this summer with no request for extension.
940 AM, which is assigned to Montreal as a clear channel, so this station will have a very large footprint at night, was last used by AM 940, a Corus-owned station that began as 940 News and kept cutting resources and changing formats until it finally shut down in 2010.

The missing decodes are from a couple of files, starting part way into one of them. A little suspicious of the decodes once it started up again-  would expect more from Kensington & New Bern. Could be more problems with decoding that didn't fully recover, or the stations just happened to fade out. Can't wait until the AFE822 arrives, then can have two of these things going on separate antennas.

I looked at the files and there was nothing of interest at the time of good decode to when it stopped (at least visually or audibly).

Once this batch of 11 are done, I'll review the results. If there is missing data, I'll isolate and process to only the ones that show problems.


A "good" thing with all of the QRM here (currently have two strong & disctinct sources, one that's NW-SE from me and another that is NE-SW  ), is that this is an opportunity to see how resilient the DGPS signals are to QRM.

All of these appear to be valid.

Nothing interesting in the stations, but what on earth happened between ~1100 and ~1220Z? There are some decodes, so I know it had some data. I'm running it again with all of the files and see what happens. When looking at the recordings in the Perseus s/w, can def see QRM, but it existed long before 1100Z and went until around 1420Z, otherwise, all of the stations are there happily transmitting with 317 being very strong and shouldn't have been interrupted like that.

Initially thinking this may have been widespread status, did find the USCG's DGPS status page. Looks like a few will be going offline briefly in the next few weeks:

Was tuning around a short time ago (~2300 UTC) and now some sporadic QRM has set in, fairly strong repetitive static across LW & MW (different than the QRM earlier in this thread). With this much QRM, not much DXing tonight.   

From ~2320 to ~2340, had some sort of data that is across LW, MW, and HF, with its signal every ~16 kHz.  This one is periodic and has been going on for many years. Not the water nor power meters (those are 900 MHz).

Dear FCC, you want to revitalize AM? Start with cleaning up the spectrum. Yes, I've brought that up before and will continue to do so. I always thought jamming was illegal- regardless of its intentional or not. This sort of QRM interferes with the DGPS signals and could cause problems with navigation. Safety & all of that.

I've been whining about my QRM. Here's what it looks like in four screen shots. All from the Perseus with the Wellbrook ALA1530S+ taken late morning CST. Loop was in four positions: N-S, E-W, NE-SW. and NW-SE. Maximum QRM is E-W and minimum is N-S. Buried telephone nearby (runs N-S) unknown about buried power. House is served with underground power, but house is 75' away. Straight east is underground vault for power going into my house, so perhaps the dirty power here has now become even filthier.


Minimum QRM, NW-SE:


Maximum QRM, NE-SW:


North-South (minimum QRM):


East-West (maximum QRM):


Spectrum display of max QRM (E-W), with peak hold set.



Note: Edited since original post. Found that antenna angle was about 45 deg off from what the dial said. Took new screenshots and added the spectrum.

Day and a half recording with the loop running east-west. Success in Hawaii & Alaska. Danang is definitely false, as the times of decode are during Danang daytime (and I'm not good enough to DX at high noon). The rest appear to be valid catches.
