[Elecraft] K3 Feature Idea

[K2MK]

Hi Wayne:

With regard to the VFO coarse tuning. I would use it if it was disabled when 
the VFO A LOCK function is active. At the present time, the knob is not 
locked out.

I wonder if that was an oversight or if there is a logical operational 
reason to keep it enabled.

Sorry -- geekSpeak  :)

Suppose the VFO were tuned to, say, 7040.23, in CW mode. Further
assume your CONFIG:VFO CRS menu parameter is set to 1.0 kHz (i.e.,
your COARSE tuning step is set to 1.0 kHz in CW mode). If you then go
into COARSE mode and move the VFO up one tic, you'll get 7041.23 with
present firmware. In the future you'll get 7042.00: "quantized" to the
nearest "quantum" which in this case is the next even multiple of 1.0
kHz.

The same will apply if you have the RIT/XIT offset control enabled for
use as VFO coarse tuning when it's not being used for RIT/XIT (see
CONFIG:VFO OFS). The control will be quantized just like the VFO when
it is in COARSE mode.

The VFO already quantizes with smaller tuning increments selected
(e.g. 50 Hz). So quantizing COARSE increments would be more consistent
with present behavior.
