Clock is synchronised - I am running Nettime on the tablet.
HOWEVER, YAHOO !! I have found the reason it wasn’t working.
In case others are using an FT-817 - this is important.
I set the FT-8 software to select the digital mode in the settings which it does via the CAT commands. In the FT-817 there is support in the menus for different data-modes and the default set-up is RTTY. RTTY ALWAYS uses LSB irrespective of band and of course all modern data modes use USB irrespective of band. When I changed the FT-8 software to use USB mode rather than data, it started recieving and decoding!!
Of course it’s better to have the narrower filters of the Digital mode, so I went in and configured the “USER-U” mode in the FT-817 as the default digital mode on the FT-817.
I changed the WSJT-x FT-8 software back to use digital mode and PRESTO it kept decoding!! The drive level needed adjusting to remove any ALC and then checking PSK reporter and my 2.5 watts of FT-8 is being received by two lads in the North of Scotland - thanks guys!!
Big relief - the reason it wasn’t decoding was because the FT-817 was listening on the wrong sideband.
