K3: too easy to overwrite dial memories

[Dave, G4AON]

The whole VFO/memory management with the K3 is very poor. Other
transceivers, many at less than half the price of a K3, have a V/M
switch so you are either using it in VFO mode or "channel" mode, even
being able to scan the memories. Having to press a button then rotate
the main dial knob, then press another button to listen to each of the
60m channels, one channel at the time is hopeless. It's just as well I
have my TS480 for 60m as the K3 is so awkward to use in a channelised
manner!

-----------------

For about the 3rd or 4th time I've tapped V->M, selected a memory (on of
the 60m spot frequencies, the only global memories I have), rotated the
VFO dial, and then tapped V->M again and overwrote the memory with the
current VFO setting.

Once the 2nd RX gets out it would be nice to get some attention paid to
the memories; channel mode, especially for 60m but probably also for
general use (think mobile ops; another K3 owner has suggested the VFO B
knob for this.), making it harder to overwrite, etc.

This has no bearing on the current discussion but might be interesting to
some. The "button that shuts down jet engines" is protected only by the
human instinct to survive. We sit there for thousands of hours in the
cockpit and never have any impulse to move those switches to the "cutoff"
position, except during an intentional engine shutdown. (You usually have to
lift and move to get to the cutoff position; you can't brush against them
and move them.) I can only recall one case where a B767 pilot moved both
switches to the cutoff position unintentionally. He thought they were
something else I think. That event had a happy outcome. He did resort to an
"undo" procedure.

Some airplanes with overhead panel pushbutton fire switches are guarded
mechanically to avoid hitting them with your head or shoulder when you get
out of your seat. (The fire switches cut off fuel to the engine, among other
things.)
