Spark SDR 1.0 beta 11

Be warned this is beta software and has had far less testing than the pre 1.0 versions.


This initial release will only work on Windows 8.1 64bit and above.

The Visual Studio 2017 redistributable is needed

Only Hermes Lite radios are supported


Simply unzip to a directory of your choice and run sparksdr.exe

Settings and error logs will be saved in c:\users\##YOU##\AppData\Roaming\m0nnb\sparksdr. This has changed from the pre 1.0 code so old settings will not be used or affected.

There are now two log files of interest, log.txt and sparkcore.log

Release Notes

FT8 will autodetect if wsjt-x 2.0 is installed and use the appropriate mode for tx

Known Issues

Compound callsigns cannot be sent in FT8 mode.

The Audio resampler control is currently disabled so audio may not be as good as previous versions.

Many performance features are disabled so cpu load may not be optimal (but should not be bad).

The new panafall display is a work in progress.

Please report any bugs / comments to SparkSDR Google group
