Spark sdr

Spark SDR 1.0 beta 9

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

Requirements

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

Installation

Simply unzip sparksdr_1_0b9.zip 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

Tuning error on favorite+ fixed.

Silence returned on virtual receivers that don't fit in the available bandwidth.

Waterfall agc tweaked and spur removed from extreme left of display.

Favourites can now be added to and + button added to open favourite in a new receiver in one go.

Initial attempt at smart filter switching for multiple receivers.

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.
