[Elecraft] new K2 accessory / feature

[inventor61 .]

I worked with WA2EUJ at Hobby PCB to modify that amplifier's firmware so
that my amplifier would connect to my nearly-20-year-old K2 and add
automatic band changes and one-cable interfacing.

The video shown at this URL describes what was done and the results.  I am
happy to back this up, as the initial field user with the most hours on the
setup.

Here's yet another reason to dust off that terrific K2 that may be just
sitting in storage or on a shelf, forlorn and silent, yet still a magic
little gray box that changed the hobby a generation ago.
