![]() You don't need any additional "sound card drivers", "protocol engines", etc. The fldigi suite is a self-contained suite of sound card modes and applications that are coupled / integrated with those modes. ![]() So to save readers at least some of my grief at figuring out the fldigi suite, here's my capsule explanation. The software is mostly used by amateur radio operators who connect the microphone and headphone connections of an amateur radio SSB or FM transceiver to the computer's headphone and microphone connections, respectively. Wikipedia's article on fldigi has a reasonable intro paragraph:įldigi (short for Fast light digital) is a free and open-source program which allows an ordinary computer's sound card to be used as a simple two-way data modem. (Yes, that's the author's preferred capitalization - all lower case). In my initial encounters, I had a hard time "grokking" what exactly the fldigi suite is, and what it does , and how it works. To reconstitute RadioMirror in 2021 would require cobbling together some old Windows code for the server and client, terminal node controllers (TNCs) or using DireWolf's "KISS" interface, Windows computers, etc.Īs I explained my enthusiasm for the RadioMirror concept, my friend, colleague, and co-conspirator on many of my Amateur Radio data communications experiments Bill Vodall W7NWP* verbally "smacked me upside the head" (probably a very dated cultural reference) by reminding me that there is a "RadioMirror" mode in the fldigi suite, specifically flamp (PDF). Again, as far as I'm aware, RadioMirror never quite got going, other than some experiments to prove out the concept. My two articles on RadioMirror - Revisiting RadioMirror and More Thoughts on RadioMirror, constitute a reasonably deep dive on the use case, concepts, and details of RadioMirror.
