FT817 first fiddle...
I now have a second Signalink USB complete with the Yaesu cable to go with the FT817. This is actually the third one to arrive here, the second was mis-advertised as having the radio cable - it didn't so it is going back because the price is £20 more than a competitor, a little less than the cost of the radio cable. Serves me right for trying to save a couple of quid!
Anyway, FT817 and Signalink all cabled together and no antenna. Hmmm. Ok let's try into a dummy load, should be good enough for across the shack with FT8 running on the Linux box. Nothing received.
Ah, it's a Windows box and 1.5 seconds adrift. Sync the time. No change.
Ok. Set WSJT-X to 2m and use the front antenna which I have. Nope, nothing sent.
It is always a good idea to read the manual before fiddling! Let's change the display to power. Ah. No power... Hmmm.
Ok, transmit from the Linux box and I can see that on WSJT-X via the FT817. So it receives fine.
Did I mention the manual?
Set radio to DIG. Works fine now! Funny, that.
