I have a YT-100 connected to my FT-857d in my remote-by-default shack in the attic (i.e. I operate it over a VNC connection from elsewhere in my house). Whenever I change band I have to go up to the attic to press the button to re-tune the ATU. It's an easy enough process as it finds the match itself, however it's a bit of a pain to do.
Question is, if I just start transmitting without re-tuning, will the ATU detect the mismatch and trigger a re-tune on its own?
Follow-up question (if it doesn't re-tune itself) - is anyone aware of an interface between the remote jack on the rear of the ATU and a PC to simulate pushing the tune button?
