Over the last month or two, I’ve been watching the development of WSJT-X and the increase of activity on the mode. In fact I tried it quite early on, on 3.5MHz with Mark, M0DEV. However, although I could get it to receive and transmit, Mark couldn’t decode me.
Mark looked at my signals and there seemed to be some sort of artefact with the audio. We wondered if that was the problem. Time came and went and I didn’t have a chance to look at it properly.
New versions of the software have come out and seeing Julian G4ILO’s post at RTTY and JT9 earlier this week, I thought it would be fun to try it again. Although this morning, I have tried two different rigs and two different interfaces, no one has yet decoded me! Of course, that could be sheer bad luck – but no decodes on PSK Reporter either.
I’ve tried reducing the audio output as much as I could in case there was anything causing an issue.No! Bear in mind that I can use exactly the same setup on JT65A and pretty much any other data mode that you care to shake a stick at. It’s all rather puzzling.
The next experiment will, I think, be to try a different USB soundcard and see if that makes a difference.
It’d be great to get it going, as it looks an interesting and a useful mode.
