Brett, I think you are referring to the fact that many audio amplifiers have
an output impedance which is much lower than the load they are designed for,
with the result that a lower impedance load receives more power. This is not
the same as sensitivity, which is measured in sound pressure dB
Don,
Do you have any particular brands/types in mind? If the bump in the cable is
small, it would indeed be worth looking into. I do assume that these units
would be battery-powered, so that one might be stuck with an exhausted
battery though. BTW, just to clarify, I don't suffer from hearing
VFO/memory operation is done pretty well on the Kenwood TS480 and TS570,

can't also use their memory arrangement too... For those who haven't

Have you configured your sub rx to have a noise blanker? I think you
have to go into the menu for the KNB3 and then hit sub and turn that on.
Then I'm not sure if you have to also use BSET to enable it or not but
this is at least a thought of something to check.

I've written to support, but I figures that I'd also post the trouble here for
others to peruse.
I've finished the KX1 and KXAT1 and thought things were going ok, but several
days ago, I turned on the unit and heard no relay, or only a single relay and a
blank display.
So long as they remember to keep rapid tune via the RIT knob function
set to not round off the frequency (VFO OFS menu item), this can lead to
the accidentally loss of a contact on CW.

The electrical specs of this radio may not be as good as the K3 or other

It should be easy enough to slide the cover back and access these
