[Elecraft] Using T1 with KX2 or KX3

[Dave Fugleberg]

Understood.
The T1 manual indicates that you can manually initiate tuning remotely by
pulling the ring of J3 to ground, so running an extra control line from the
operating position to the remote T1 could work.
It also details the protocol for sending band info to the T1 to recall the
previous tuner settings on a per band basis. The special cable for the
FT-817 uses this.
The KX2 can be configured to send the current band out its serial port as a
CAT command. I imagine one could build a device using an Arduino or similar
to grab that CAT band data and send it to the T1 when requested.... Might
be a fun project for someday. So many project ideas, so little time...
