Digital modes within SDRUno?

This is probably a pie-in-the-sky thought, but what the hey - it would be nice to have some plug ins that can do digital decoding. Certainly use the various ham modes such as PSK31, Olivia, FT4 and 8, etc. as well as some of the non ham modes such as SITOR-B/NAVTEX, HFDL (with the ability to read th...

Re: Antennas for City Dwellers

I would recommend a loop - they do a good job of rejecting noise and you can put them on a small tripod. Many don't take up that much space, either. See this topic...viewtopic.php?f=8&t=4575

Re: Antenna for LW

If you want to learn about LW and what you can hear, the Longwave Club of America, which has been around for a very long time, is the place to be. It specializes, as the name suggests, on stuff 530 khz and down. The URL is: https://www.lwca.net/

Ham Radio Deluxe URL in the Getting Started article

I goofed when I supplied all those links for the Getting Started article - just one, thankfully. Ham Radio Deluxe's correct URL is:

https://www.hamradiodeluxe.com/

This includes the well known DM780 digital decoder that is part of the Ham Radio Deluxe package

Thanks...Mike

This includes DM780 which is a part of the Ham Radio Deluxe package

Re: expand the list of useful links

OK Jon here's a starter list of links and topics. Consider this list as a work in progress. If you (or the other admins) think of other things that should be added, now is the time to do it. These links all come from the RadioReference wiki, which has over 10000 (yes you read that right) articles on...

expand the list of useful links

I read the PDF in the support area regarding useful links. While that's a start, it misses a huge amount of programs and DLLs (EXTIO, for example) that are mentioned throughout many of the videos. How about something that can give people where they get things like WSJT-X, MMSSTV, MultiPSK, Krypto500...
