Exciting news! 8-band skimming is now available on the Red Pitaya.
Pavel Demin has released a new version of his Red Pitaya SDR software that can support skimming on up to 8 bands simultaneously at 192 kHz, making it more powerful than the QS1R, which could only skim 7 bands. Upgrading and instalation is very easy. Instructions how to do it are available here
CW & RTTY Skimmer Server captures all CW & RTTY spots on eight bands simultaneously and can optionally send this data to online central database Reverse Beacon Network, which includes a mapping facility.
