On winderz, it has remembered the last folder you did something in for as long as I can remember. I'm now running 1.1.0b5, but see no difference in behavior.

A new beta of Amalgamated DGPS is available. Version 1.2.0 b2 has two major changes:

No longer uses PortAudio for sound input, which should improve stability (previously it would often crash after a while when decoding from live audio vs a recorded file)

Now a 64 bit application for macOS.

It can be downloaded from the website: http://www.blackcatsystems.com/software/dgps_decoding_software_sdr.html

Hi Chris,

Question: with the decreasing number of US stations now on the air, is there any way to tell what stations are in the program's built-in list? I am decoding SDR files that are up to 10 years old, and wondered whether all the stations on the air at the time of the recording are in the list. I looked through the included DGPSSTATIONLISTING.TXT.BAK.TXT file and wondered if that represents the list that will be used when running the program? I also noticed that some of the stations in that file had a "-" in from the their frequency, and wondered if this signified a station that was not longer being checked by the program?

Thank you, and thanks for making the program available!

Hi Brett,

There's a built in database of DGPS stations, which can be overrided with your own text file if named dgps_station_list.txt

DGPSSTATIONLISTING.TXT.BAK.TXT can be used as a basis for creating that file. Now, I will add... I tested doing that when I first implemented using an external station listing file, but have not tried it since, and I think I had a report from someone that it didn't work, but that was a while go, and I am not sure if they ever resolved it or not. In general, everyone is just using the built in station listing.

The stations in the file with a - are indeed off the air, and there are more since (that was from the big shutdown a few years ago).

The USCG site has a list of stations off the air, I would use it as the official reference. Also check the logs here on the HFU.

Very good; I just discovered the UNID window, and noticed that the stations showing up there correspond to stations that are marked as "off the air" so that tells me I need to check UNID's in order to get a complete listing for these older recordings.

Thank you!

The UNID window is very inetersting and throwing up a few active stations here in Europe such as 304.5 #535 Klaipeda. Is it possible to export the UNID data?

I don't believe it is, although I can look into adding something to do that.
