ShackDeck 0.1: public receivers, decoders and a logbook in one window

The first build: hundreds of public SDR receivers with a real waterfall, FT8, FT4, WSPR, RTTY, PSK31, SSTV and CW decoders, and a logbook with ADIF, callsign lookup and a map.

ShackDeck: the receiver on 20 m FT8 with the waterfall and decodes

The first public build of ShackDeck does three things that usually take three programs.

Listen. The receiver list holds hundreds of public KiwiSDR and OpenWebRX receivers around the world. Every one is checked by a real connection before it is shown, so the list contains only receivers that answer right now. They are sorted by distance from you, and each has a flag and a place. Pick one and you get a waterfall, a tuning knob, a passband and the usual modes.

Decode. FT8, FT4, WSPR, RTTY, PSK31, SSTV and CW are decoded inside the program, on the audio that comes from the receiver. Every decoded station lands on the map and in the on-air table. If you wish, the decodes go to PSK Reporter under your callsign; that is off by default.

Log. The logbook takes contacts by hand or from the decoder, imports and exports ADIF, looks callsigns up on QRZ.com or HamQTH with your own account, follows a DX cluster and draws worked countries and grid squares on the map.
