Digital Modes

Just getting into the digital modes. Here is the SDR waterfall on 20m.



On the left are PSK31 signals, in the centre Hellschreiber and on the right JT65 mode.

I am using two programs to view these JT64hf109.exe running under Wine on OSX, and native flidgi.app on my Mac.

Here is some Hellschreiber signals and their decode
