ARLA/CLUSTER: Aumenta o numero de utilizadores do modo digital FT8 que é 4x mais rápido que o popular JT65

[João Costa > CT1FBF]

Move over JT65 for a new kid on the block

The digital mode *FT8* has caught on, luring many using the popular JT65
weak signal mode.

The WSJT-X 1.8.0 beta software has the FT8 mode described as fast with an
entire QSO taking about a minute, which is four times faster than JT65.

Developed by Steven K9AN and Joe K1JT – the name FT8 stands for its
creators Franke and Taylor and 8-Frequency Shift Keying modulation.

Using a 15-second transmit and receive sequences it provides 50 per cent or
better decoding probability down to minus-20 dB.

An auto-sequencing option can also respond automatically to a CQ call
decoded reply.

An excellent HF DXing mode and multi-hop sporadic-E propagation on 6 metres
where deep fading may make fast and reliable QSO completion desirable. Some
are comparing FT8 use to that of JT65, and believe more are on air trying
the new one.
