These are free or low-cost programs of interest to amateur radio operators.
|N1MM Contest Logger is programmed for virtually any contest or QSO Party. It supports multiple users, networking, radio control, CW and voice macros, digital contests, and much more. Generates Cabrillo logs, and can export ADIF files for other logging programs. We used this logger for Field Day with networked laptops, and it worked very well. This is the only contest program I use, and if I get it working under Linux, I’ll post the solution. N1MM is starting to work on Linux under WINE 1.1.21. Networking is OK, but it crashes when entering a non-North America callsign. See discussion at www.ckarc.ca/QST/index.php|
|Ham Radio Deluxe (HRD) is a suite of free Windows programs providing computer control for commonly used transceivers and receivers. HRD also includes mapping, satellite tracking and the digital mode program Digital Master 780 (DM780). HRD is designed for Windows 2000 or higher (XP, Vista, 7), also Internet Explorer 6.0 (or higher) is required. It may work with Windows 98 but this is not supported. The policy is to support Windows versions which are supported by Microsoft. HRD works in Linux under WINE, and so does the satellite module, but it sometimes crashes when changing tabs. PSK31 Deluxe runs fine.|
|EasyPal is the work of Erik VK4AES. This software uses the DRM (Digital Radio Mondiale) encoding to allow the sending of image files over an HF voice channel. This is known as Digital SSTV. It’s constantly being revised and updated, so check often for new versions.
To run EasyPal under Linux:
Running EasyPal under Linux was tricky to configure. The above list suggests the settings that worked so far for me. I may have forgotten a step, or something listed above may be unneccessary. I don’t promise EasyPal will work on your Linux distribution, but it works on my Debian system with WINE-1.1.13 (self-compiled). If you have problems, try adjusting one thing at a time until it’s isolated. Known issues include waterfall text problems (it uses c.exe which is 16 bits), RS encoding isn’t working yet, and the waterfall sometimes hangs when transmit ends. I’ll post the fixes.
If you encounter a situation where you can’t get MSC even with a strong signal, check your sound card. I had problems in the laptop when “speaker” acceleration was enabled! In typical Windows fashion, this setting wasn’t saved between sessions. EasyPal also depends on an accurate sound card clock. This should be investigated if MSC won’t lock. My onboard sound card stopped decoding EasyPal (and PSK) and I discovered the clock was wonky. I finally started using a cheap USB sound device and it solved all the issues with my laptop.
|GIMP is the GNU Image Manipulation Program. It is a freely distributed piece of software for such tasks as photo retouching, image composition and image authoring. It works on many operating systems, in many languages. This program can do most of what PhotoShop can, and should cover the image editing needs of most users. (more…) A great companion for EasyPal!|

|WinDRM was developed by HB9TLK from a relatively new broadcast standard called Digital Radio Mondiale (DRM) and its open source encoder/decoder named Dream (http://drm.sourceforge.net). DRM is based on a proven data communications technology called Coded Orthogonal Frequency Division Multiplexing (COFDM) with Quadrature Amplitude Modulation (QAM). COFDM uses many parallel narrow band sub-carriers instead of just one single wide band carrier for transporting the data. As a result, WinDRM provides an efficient and robust method to exchange information over HF including Digital Voice using open source CODECs. WinDRM utilizes Forward Error Correction (FEC) and an Automatic-Repeat-Request (ARQ) mode to ensure error free data transfers.|
|Reed-Solomon Encoder/Decoder RS encoding makes a DRM signal more robust. EasyPal includes built-in RS capability, so this program allows other DRM software to decode (EasyPal) RS-encoded signals, and convert files to enable RS-encoded transmission.|

|SDRadio is a software defined radio receiver by Alberto I2PHD.|
|G8JCF’s Software Defined Radio The G8JCFSDR is an SDR which uses RF front-end hardware to down-convert RF frequencies into the 0~24KHz range accepted by most PC soundcards. The PC reads in the soundcard signal and carries out all of the filtering, demodulation, AGC, and notch filtering in software rather than hardware as would be the case in a traditional receiver. Because the receiver is all software, there are things you can do which would be almost impossible in h/w, how about -100 dB filters for a start !|
