I'm working on adding some NDB related features to DX ToolBox, including logging, as well as some identification aids. Here's some of what I heard while testing them:

I'll check for it again tonight, to make sure my rusty CW skills are not to blame.
The NDB list in DXTB (based off the RNA list) has a partial ID search field, type in the frequency (either carrier or sideband where you are hearing it) and a partial ID string (could be any one or more of the characters in order, so first character, first two, last two, etc) and it will give you a (hopefully short) list of possible beacons. Right click on the guilty party to log them.
I seem to notice a relative lack of DX NDBs coming in during daytime, vs what I get on DGPS.
There's an NDB chat channel on Ryver now, as well. I think I am fully initiated into the Dark Side now. So many more targets than DGPS. If only I could automate things...
-
I will check also tonight. I only record a 150 kHz span overnite, and rarely do I have the time or energy to go thru the span completely. I alternate low and high ends of the band, and tonight the high end is up for recording.
-
I seem to notice a relative lack of DX NDBs coming in during daytime, vs what I get on DGPS.
The DGPS stations are designed for coverage over as much as a couple of hundred miles whereas a typical NDB is used relatively close in as, say, an outer marker locator or a missed approach fix.
The power output of a DGPS station can be 10 to 100 times that of a NDB.
IMHO, daylight NDB Dxing is the ultimate challenge. My best daytime DX was 360 PN Port Menier QC 1021 miles... but it was maybe cheating a bit using greyline.
To me, anything over 300 miles daytime is definitely DX. What do you think?

I was just checking out the band to see what I could get in the daytime, well mid morning anyway, and since it is December the D layer should not be as strong. Best I could do was YMW on 366 at distance of 722 km.
I'm tempted to record a wider swath of LW for my DGPS decoding, so I can also check it for NDBs. I'm thinking of using the DGPS decodes as a beacon as to where there could be an opening at a particular time, then check that portion of the recording. Say for example when European DGPS stations appear. Which 250 kHz portion of LW would be most fruitful to record, bearing in mind it needs to include the 285-325 kHz DGPS band?
-
YMW, nice catch in daylight.
There seem to be more NDBs above the DGPS band than below but the pickings get pretty sparse above about 425. So, if you record from 200 to 450 you pretty much have it all covered... if that is what you had in mind.

Perfect, thanks. I will try recording that tonight.
YMW still coming in at 1922z. Of course now it is getting dark up there, or will be soon.

YMW vy weak hr late this afternoon.
Good luck with ur recording.

371 GW aka as Great Whale River or Grand Riviere de la Baleine... some of these Canadian NDBs have really cool names.
Good idea on marking ur QTH.

Great logs, Chris!
Keep an eye open for MOG 404, Montague CA. 25W but this sucker really gets out, and I see it several dozen times a season. It is generally an easy catch on the LSB. There are times when it is much stronger than locals such as CM 407.
Best bets for BC are UAB 200, 350 NY, SX 368, and 385 WL.
-
Also on 368 look for ZP Sandspit BC located on a point of land on east coast of Queen Charlotte Is. just off BC... excellent location gives it a good signal.
-
A nice haul in about an hour this evening. Lots of Canadians. And my first from ND.

YX 410 is a great log. You need to look that one up in the RNA!
I see you figgered out PYA 260. It's keying currently looks more like PTWA.

Yeah, I noticed YX was listed as an icebreaker. So I guess it is a mobile NDB?
I see you figgered out PYA 260. It's keying currently looks more like PTWA.
There were a few others I did not log because I wasn't completely sure I was correctly interpreting the wonky keying.
It's very interesting how at times two or more NDBs mix on the same frequency, and it's tough to pull out the IDs when they happen to be on exactly the same sideband frequency, I either have to wait for propagation to change, or if the periods are different enough, for one of them to slide to a period of time when other(s) are not transmitting, and the ID is in the clear. Or give up and move on to another frequency :)
This is giving me some software ideas though...
-
There doesn't seem to be any sense of urgency in repairing some of these miskeying NDBs.

I wonder how many of these are Zombie Beacons... no one even remembers they exist. But they're still plugged in, and sorta transmitting.
-
With everything going GPS, these old NDBs are becoming low priority.
Also, a lot of NDBs (and VORs as well) are being decommissioned and in the process the documentation and reality may not always match.
-
I'm making some modifications to mySdrPlayback, to let you zoom in on waterfalls from SDR recordings. Now I can spend lots of time checking my overnight recordings for NDBs!
You guys should visit the Ryver chat, we even have an NDB channel now ;D
-
Yeah, I noticed YX was listed as an icebreaker. So I guess it is a mobile NDB?
It would seem so. Then I have to wonder what is the purpose for navigation. I guess it must be so that the helicopters that will land on its deck can find it or to aid with local Coast Guard activity (who have presumably been advised as to its true location). Because if its location is not on an NDB chart, it's not clear to me what is the benefit to general aviation.
-
Latest loggings. I am starting to use a utility I wrote to display high resolution waterfalls from the overnight SDR recordings. It is not the automated NDB decoding I would eventually like, but it helps.

Some additional loggings, these were from trawling through the overnight SDR recordings for DGPS, with a wider than usual bandwidth to cover most of the NDB band as well, using a new version of mySDRPlayback, which lets you get high resolution waterfalls for arbitrary parts of an SDR recording. Then using DX ToolBox to quickly search for matching IDs for a given frequency. One of these days I need to make a video showing the workflow.

Look at the heavy black marks in the Sherbrooke<->Niagrara Falls corridor. Also, lots of them in western North Carolina too.

A few more NDBs extracted from the overnight DGPS SDR recording.
