Listen, analyse, decode
Pick a receiver by country or distance, switch to the next one that has your frequency, keep the good ones in favourites. The spectrum, the waterfall and the decodes in one view.
ShackDeck is the logbook, the receiver and the decoder together. Keep your log, listen through public SDR receivers or your own radio, decode FT8, APRS, weather fax and more, and see every station on the map.
The log, the map, the stations on the air, the receiver and the waterfall. No switching between five programs.
Contacts by hand or straight from the decoder, so the log never holds a QSO you did not make. ADIF in and out, callsign lookup, DX cluster, worked countries and grids on the map.
Hundreds of public SDR receivers, checked live and sorted by distance, with a real waterfall and a tuning knob. A catalogue of stations worth hearing, each with its own receiver.
FT8, FT4, WSPR, RTTY, PSK31, SSTV, MSK144 meteor scatter, CW. Decoded on the spot, every station on the map in the colours you know.
Stations, objects and weather stations with temperature and wind on the map, every packet in the list.
DWD sends weather maps several times a day. ShackDeck catches the start tone, lines up the picture and draws it line by line.
Every station heard by a ShackDeck user gets a page: who hears it, on what bands and hours, and the confirmed contacts. Register to add your profile.

A chart arrives in ten minutes at two lines a second. ShackDeck finds the phasing, measures the line period so the chart never leans, and ends the picture on the stop tone.

Look up any callsign: who hears it, on what bands and at what hours, and the confirmed contacts.
