I had been using my Remoterig setup with a TS-480HX, and it works great. I decided to try my TS-590, and use the Kenwood software. I made the cables, but on the control end, I am using the function "Use USB Com Port as COM2," because I don't have a serial port on my computer. On receive it works fine - everything works perfectly. On transmit it is another matter - it does not work. Oddly, when I try to use the internal antenna tuner, the rig hangs on transmit. To get out of transmit, I have to turn the 590 off and back on again. Leaving everything hooked up, I went out to the garage, pushed the "Tune" button, and the 590 worked fine manually.
On the Remoterig units, when I changed from the TS-480 to the TS-590, I simply set up a new profile, and left all the settings the same except for the settings that were in the Remoterig manual, for "general Kenwood." I wonder if there is something I'm missing. Any thoughts?
