All valid points but take note of K9HZ's work as a start. Nevertheless, let's
say native Ethernet control isn't worth the engineering effort. That should
not preclude the integration of RemoteRig as an option into a K3/K3s.

necessary. The most efficient integration would require a redesign of their
board as well as Electaft's boards.

Correct. JT-65 has common frequencies on each band. Then JT-9 is about
2 kHz higher from JT-65, thus the move in frequency. There is a box to
be checked on the application when changing from JT-65 to JT-9. It is
best if the radio is under CAT control. Most issues in this regard are

What you all fail to realize is that RemoteRig is a Microbit product, not
an Elecraft product. It's designed to be used with a number of radios.
What I'd like to see is RemoteRig in another form factor, with some type of
high-density connector that has all the important signals.

What is your proposal for the host-side interface? Pretty much all host
programs these days use a serial interface. We usually use this through a
USB-Serial adapter or through built-in serial ports, which are rapidly
disappearing. To make this viable we would need drivers for all major

From time to time, my radio club collars me to do a program at one of our

points I try to leave the crowd with:
1. There is no such thing as the perfect antenna. Each is a compromise of some
sort.
2. No ham
Indeed, and yet it's called wireless. A non-ham visitor once asked

up at the center by a willing (and tall) campmate. The

I’m interested in where this one’s going. Restrictions on my living
accommodations relegate me to an indoor wire. I managed to work coast to coast
with the KX3 and JT65 using its internal tuner. I’d like more ideas.
