A remote tuner that could handle 500 or 1500 watts to match up with amps power

Hi,

Chuck KE9UW has a good idea. What he is really suggesting is that the K4 be
remotely operated by an iPad with the K4 control panel replicated on the touch

be available with the K4?

That was already demonstrated by Elecraft in what I believe was their

You can get an AT-615B from Array Solutions now and do this. I put 10 in a club

I agree. Match the antenna, whatever the Z may be, to the feed line. This is
most efficiently done at the antenna feed-point.
However with good loss coax on HF, matching at the transmitter end is easier
and less complex and less expensive.

Hi,
This doesn't sound like an encoder problem to me. Encoders have no memory,
so if the radio eventually responds to the encoder pulses and displays the
correct frequency after a delay, that delay must have occurred in the
microcontroller itself or possibly in the display module if it is an
