My first JT9-1 QSO
13 February 2013 | by PC4T Paul’s blog post about working Tasmania with 5 watts gave me the spur to try the new JT9-1 mode, so I installed the WSJT-X software. The user interface is quite a bit different to the older WSJT programs but most of the same controls are there. I never really figured out how to use WSJT, much preferring the simpler interface of Joe W6CQZ’s JT65-HF application.

| Working SM5CS using JT9-1 mode |
My experience with JT65-HF stood me in good stead as I was familiar with the sequence of exchanges, but I missed the JT65-HF user interface, its ability to decode all the signals in a swath of spectrum, and the alerts and built-in logging of it’s companion JT-Alert application.
My first QSO, also using 5 watts, was with SM5CS – not as impressive as Tasmania but sufficient to satisfy myself that I knew how to drive the program. I’m puzzled by the panoramic display though: the two peaks of the spectrum analyzer display don’t match up with the two traces shown on the waterfall.
I made the changes to KComm to allow me to log this new mode. I seem to have an increasing number of modes that I can log but not upload to eQSL.cc because the ADIF specification doesn’t yet include them, though JT9 is already there.
