The podcast RSS feed lost it’s title after a podPress upgrade. This has been fixed.
We’ve been informed of a RSS feed problem for some podcatchers that use the XML tag. Joe, K1RBY, emailed us about this problem when using gPodder, but a solution has yet to be found. Anyone else see this problem? Let us know! (Ed. Note: The problem has been fixed and will be detailed in episode 54.)
Look for new episodes of Resonant Frequency in 2011!
Dave, now 72 years old, has been licensed continuously since 1957 and is retired from the U.S. Coast Guard. He had been maintaining gMFSK, a Gnome multimode HF terminal program, and decided to create fldigi to prove he could still write code. He started with UNIX, then MINIX, and has been with Linux since the beginning. He’s been writing ham radio programs since the 1970′s. His software will run under Linux, Windows, FreeBSD, OSX, and Puppy.
flpuppy, aka digipup, is also available from Dave’s site. This is a version of Puppy Linux with fldigi, a logbook, and a geodesic calculator already installed.
Other developers are Stelios, M0GLD, Leigh, WA5ZNU, and Skip, KH6TY.
Much of the underlying code in fldigi is from the original gMFSK program, in particular the modem code. Other modes have been added since, along with the GUI.
Dave says there are about 2500 users of fldigi and he spends 50 hours per week on coding and support.
Other projects Dave is involved with include:
NBEMS (Narrow Band Emergency Messaging System), consisting of fldigi, flarq, flwrap, flmessage, and flrig, all using the Fast Light Toolkit.
A computer-aided transceiver (CAT) program that controls the Kachina 505DSP transceiver.
Dave describes how he came to develop fldigi using C++ and FLTK.
More features of fldigi:
Version 3.21 of fldigi, now in alpha test, will have the capability of sending and receiving weatherfax. It will also have an embedded browser that will work with all the PSK modes and RTTY. It has a built-in log book that stores records in ADIF files.
While not designed specifically for contesters, fldigi is adequate for casual contesters.
Fldigi will generate Cabrillo reports for many contests.
The online documentation is quite extensive, at about 140 web pages, with many illustrations. There are sample screenshots of the waterfall display for various modes and audio samples of them.
