JS8Call Now Faster

Last week, JS8Call released their version 2.0. The big improvement is that there are now three transmission speeds:

Mode Bandwidth Speed frame length Mininum SNR
Normal 50 Hz 16 WPM 15 seconds -24 dB
Fast 80 Hz 24 WPM 10 seconds -20 dB
Turbo 160 Hz 40 WPM 6 seconds -18 dB

The new MULTI decoder can decode all three speeds at once.

Tonight, I gave it a quick spin and got copied on “Turbo” by a station near Boston at -13 dB on 80 m (at 22:30).
