I found another one that just popped up and has been off air since Oct 2014:
#820 Alexandria, VA It was an engineering test site.
So I guess there still will be the odd false decode. On some of the true Dx I don't think one could ever get 10 or more logs. That is why I have been keeping a log on paper to track them. Maybe as we go in to winter there will be a change.
It's like that with NDB's too. Sometimes they are there for a few cycles then gone.
Cheers,
Don

Thanks, I will remove that one as well.

Hi Chris,
I just started using the new windoz version of ADGPS a couple of nights ago. Last night/this AM I logged 90 straight decodes of #971 Gatun Panama! One less in the bucket list. :D
Also the previous unid (684 on 325 popped up again this AM. It has been identified as coming from Southern Avionics Company in Beaumont, TX. They manufacture mostly NDB's but have an on the air test rig for DGPS transmitters. Apparently it just sends random data to test the transmitter. For my personal log use I named it #SAC as the call sign when they test NDBs on air on various frequencies is also "SAC".
When they were contacted they shut (684 down 31 Oct 16 awaiting word from the USCG if they could use 325 kHz. Don't know as of today if the USCG said it was OK or not.
SACo L/L: 30 03 56 N, 094 08 51 W

Gatun started to appear here in the logs a short time ago, I assume it was recently re-activated?
No decodes yet on 325 but I will watch for it, thanks for the tip!

Interesting. I've never paid much attention to the UNID window... until now.
I have a whole pile from the Jan 11 decodes (Jan 10, 2017 UTC 2320 - Jan 11, 2017 UTC 1625... so far (still decoding)):

Hello Chris,
I've been testing the Windows version of the Amalgamated DGPS application on a W10 system. Very nice program ! There are however a few thing that al least makes me puzzled.
- First of all I'm wondering what the difference is between the blue and the black decodes.
- The User defined stations list that comes with the program has a wrong file name : DGPSSTATIONLISTING.TXT while it should be dgps_station_list.txt as per the instructions in the Readme file
- The row sequence in the stations list that comes with the program is not correct and doesn't fit with the instructions in the readme file.
- It would be better to make the "Max zCount error" 6 as advised in the Readme file. Too many newcomers that don't like RTFM'ing drop interest while they think it doesn't work as it should.
- The readme file says "Amalgamated DGPS can decode the entire 285 to 325 kHz DGPS beacon band ". But according to https://www.ndblist.info/datamodes/worldDGPSdatabase.pdf the band starts at 283.5. Are those stations skipped ?
For the rest, I'm really astonished what this little piece of software is doing. I'm using it together with Perseus IQ files. It saves such a lot of time of decoding frequency by frequency. Really great work !
Greetings from Belgium.
73,
Guido.
