My K3 S-meter and P-3 show identical S-9/S-3 readings at 50 uV and 1uV with
an XG-2 on 40M.
Sideband and particularly band noise are different as noted in previous
posts for obvious reasons.
If your readings are miles apart, time to check calibration of both units. I
went through the
I have checked the calibration on both of my K3s with my XG-1, and the K3 S
meter is miles apart from the P3 readings in S units. If this is going to be
the case especially in SSB, just please say thats the way it going to be.
There are a lot of us apparently who are perplexed by these
Roy,
Did you calibrate the P3?
Tap the P3 MENU Button
Turn the knob until you see Lvl Cal
With the XG1 on the antenna connector of the K3 and turned on, adjust the level
to S-9.
Tap the knob.

I have calibrated both my K3 (using ABS) and P3 by the manual with an XG2
the P3 Transfer gain (db): -12.1
In SSB or AM, if I want the P3's S meter reading to match the K3's S meter
I have to change the P3's Transfer gain (db) to -32.5 db
actually if I'm running 200khz span is should be about
Before assuming that you have a problem, you should
1) Calibrate the K3 RF gain using the procedure built into the K3 Utility.
2) Calibrate the K3 s-meter using the procedure explained in the K3 manual.
3) Adjust the P3 calibration using the Amplitude Calibration procedure in the
latest P3
I have found that -8.9 LVL CAL (transfer gain) is the setting for an S9 reading
on my P3 using my XG-1. The readings track right well as long as they are not
stronger than S9+20. Signals over this on the K3 S meter are just not correct
on my P3. If I change the LVL CAL (transfer gain) to

Newly installed P3. Noticed S meter reading on K3 will be 2-3 units
higher than that displayed on P3. I've tried lengthening the signal
heights, but results are unsatisfactory:-( .
Is there another method for bringing the two more in balance?

Bill,
Alan may provide a better answer, but are you making that comparison on
the amplitude of a single signal that is substantially greater than the
ambient noise level?
If you are comparing the ambient noise level, the s-meter reading on the
K3 will vary by bandwidth, and will be lower at
What s/n is the K3 in question? Generally, I have the same issue
here. The K3 s-meter reads high compared to the P3.
BTW, there is an s-meter calibration procedure given in the K3 owner's
manual

There are a couple reasons why the K3's S meter and the P3 display may
show a different level.
As Don mentioned, the P3 will generally show a much lower level than the
K3 on noise. It's because the effective bandwidth of the P3 is
generally only one display pixel, about 1/450 of the span. Less
Al,
Yes, this does work and even the SSB sigs match very closely to the K3 S-Meter.

I might add about the K3 CONFIG: SMTR MD = ABS, that the calibration
procedure indicated in the manual may (or may not) be the proper thing
to do.
The manual suggests that you calibrate the S-meter with the preamp ON.

S-meter response is about 2 S-units lower than what you may expect.
Interesting. I assumed that in ABS mode it didn't matter if the preamp
was on
I have a service monitor, I could calibrate my S-meter if I really
understood the process, but haven't since I don't.
For my part, it was Greek to me.
Youknowwho
