[Elecraft] T1 Operational Question

[Dave B]

Hi.

I don't know the T1, but...

The WSJT programs are all open source, so you can do anything you 
want/need to do with them, subject to tools and skills availability of 
course (the latter is often the stumbling block for most of us, sadly.)

The SoftRock kits:  The embedded micro controller they use for USB<>I2C 
work, may have a spare pin or two, or you can hang another I2C I/O chip 
on the I2C bus (a PCF8574 for example) to get generic digital I/O 
ports.   I've done that to control a bank of band filters between the 
antenna and a SoftRock here.  The hardware was fairly simple, 
re-engineering the software however, is an "ongoing" project...

The other way might be to check out what Hamlib has hiding, as that is 
used with the WSJT programs for rig control.  Maybe, there is something 
in there that can send simple one byte values to a simple UART IC, that 
you can then pull some identifying code from, to poke the T1 tuner to 
change bands.   Sadly, Hamlib on Windows is usually embedded in the main 
program, so you're stuck with what it has already.

With the KX3 (+ K3, and other Kenwood remote like radios) you can also 
put the rig into AutoInfo mode, where it will spit out (among other 
things) the working frequency periodically, and when things change.   
There are other kits and products about, that can decode that info, and 
set/clear a small array of I/O bits, specifically for changing 
antenna's, and kicking ATU's into life.   It does add to the overall 
complexity however.

There is bound to be a WSJT support list/forum somewhere, you could ask 
on that to see what may be possible already to suit you needs.

73 & Seasons Greetings.

And, since the band changing is being done from within a program K1JT?s WSPR, I have a feeling I?ve got no way to do the remote control stuff per the manual. I?ll investigate the feasibility of user mods to WSPR, but not holding my breath at this point.
