[Elecraft] Linked VFO's -- usage?

[Guy Olinger K2AV]

The counter to yet another mechanical outside box is that the ability
to write firmware and update it inserts another very major
possibility, that it can be done in the digital stream without need of
extra cords and boxes.

To use the mechanical box, we must physically route the audio to the
box and plug in the headphones there. We have to mount the box so it
doesn't move around. And worst of all, I have to make it.

My microHam box doesn't treat a/b audio in this manner. "B" audio is
radio 2 with its own stereo audio output. and it labels a pair of
stereo lines RX1 and RX2. That deals with a pair of radios, not
left/right stereo audio switching. So if I actually have two radios
hooked up to it, no way to use it "creatively" to do the tricks just
with the K3 in diversity.

If I take my K3 anywhere else, like NY4A for multi contesting, I lose
the function as what I get at NY4A is main antenna, RX antenna and
power from the station, rather than a double of my now unique home
station.

Putting it in the digital functions makes it instantly portable.

So, understanding your suggestion completely, and with no malice
whatsoever, I decline, and still lean to the future with something
that can be put in a macro stream sent to it from MM+ or whatever. I
CAN take my MM+ macros with embedded K3 program commands.

Feeding the A stream to the b audio just seems to be too easy in
firmware, it's already done for non-diversity.

Use of the diversity hold is problematic because it assumes that the
unwanted half of the headphone audio is in the subRX side.
