I'd prefer it per mode. My presets are:
10 kHz - CW
20 kHz - CW/data
50 kHz - Phone
100 kHz - Phone
I usually operate CW. Switching to phone means I have to mash (that's
what we do to buttons in the South ;) ) a button to get a good span.

with the pick-off point clearly *before* the noise gate, the NB can
not possibly provide any *blanking* to the P3. There may certainly
be artifacts due to changes in the impedance (loading) seen by the

Measure the amps you are charging them with, and charge them at C/10, where
C is the capacity of them. Say you have 1200mA NiMh batteries, charge them
at 120mA overnight. You can charge up to C/1, but be careful not to
overheat the cells. You should be able to hold them in your hand.

I would agree with that... but first, there is another point that needs
to be rationalized in the K3 (and, I presume, the KX3 also).

of different data sub-modes. Many of those sub-modes require quite
different settings for the

I think it would be helpful to center the span on the A-cursor when changing

You could use an "active antenna" (amplified) with the KX3 -- just don't
transmit into it. The Grundig probably has the equivalent of an active antenna
amplifier built in.

Wouldn't the fact that the bandwidth is much more narrow in the KX3 than your

Both the bandwidth and speaker have been taken into consideration. With a
short passive whip, the KX3 is far behind the Grundig, because even strong

However, an active antenna makes the KX3 much better, but still not
significantly better than the little Grundig.

Yes, the NE612 should show plenty of gain. When it does not, the usual
