Same here. I haven't discovered any practical use for the s-meter
going to the top of the scale as the gain control is reduced.

Actually I DID read your post. You said:

I quite disagree with "large
I think the S-meter is there because it's expected to be there. A "Ham"
receiver has an S-meter. A lot of people would not buy one without an
S-meter, so any company who wants to attract Hams to their receiver need
supply one.

Well, from one perspective this is, of course true. But this arguement leads
to the question, why is an s-meter implemented at all on the K3 then? If it
doesn't really mean anything, why have it?
I'm more interested in exploring other questions. Having decided it is of
value to implement an s-m
Guy, you obviously didn't read my post.
I said the signal path was analog all the way to the second I.F.
I agree that generating a stable, low phase noise local oscillator signal
digitally is great or as you might say "smart". But that's not in the
signal path. Only the analog result - an r.f.
Can someone explain for me this recurring fixation on the K3 S-meter? I
honestly don't understand why it is such a big deal for some folks. If
you need accurate relative readings, such as when plotting antenna
patterns or something, you just pick some settings and leave them
alone. Absolute

"If one has chosen "absolute" s-meter performance which is already
un-analog, it would be nice to see the input level regardless of the
RF gain setting, and perhaps just slow "plink" only the top segment
that would be "covered" with the analog convention. "
Exactly my view, Guy. "Absolute" on

Please, could we refrain from using the venacular of "fooling" an

Don't forget that the K3 *is* a largely analog radio. The signal path only
goes digital at the second I.F.
I believe the K3 (and K2) handle manual RF gain control just like any analog
radio does - they insert an adjustable d-c bias gain control voltage that
replaces voltage originally created by t
I wholeheartedly agree. This behaviour has always irked me.

They're not likely to see this, rolling up to Dayton, but rolling the
s-meter up scale as you roll the RF gain back is making a digital

Sometimes we're just too picky about that "S-Meter". Many years ago (almost
before my time) a number of receivers had no meter but instead calibrated
the gain control in S-units (or the S-unit's ancestor, the "R-unit"). If you
wanted to see how strong the signal was, set the gain for a comfortable

Helpful comments, Jim.
I ride the RF gain control on the K3 to very good effect. The only problem,
as you point out, is that the S-meter won't read signal strength at the
antenna with the RF gain wound back. I have my K3 s-meter set in absolute
mode, so using ATT or PRE does not influence the s-m
Hi Mike,
The K3 has a lot of receiver gain. You can reduce it to something more
like the gain of a K2 by setting CONFIG menu entry AF GAIN to LO. This
will have no impact on performance.
Have you already tried turning the preamp off? It really isn't needed
on the bands from 160-20 m unless

You may be mistaken about why the noise is loud. Many of us live in
places where there is a lot of electrical noise. When I lived in
Chicago, my noise level was rarely less than about S6, and often S9.
There are three good w

I would like to find a way to reduce it somehow maybe artificially. This would
