Hello again,
Update to my last post: I turned everything off, went and had a cup of
coffee, came back and tried the RF gain calibration routine again with K3
Utility - worked just fine this time. So, not sure why those errors. I had
turned everything off and re-booted the K3, restarted the
John - I would say that if it is just flickering on and off that is
exactly right. It does at least show that the receiver is live and the
residual noise is registering on the S-meter. Perhaps if you shorted
ANT1 to ground the flickering might reduce.
Personally, if my S-meter did not
Hello John!
In ABS mode this is normal. It is a consequence of offsets the DSP is
doing to account for the settings of ATT and PRE, along with the method
used to pass S Meter information to the MCU.

After the RF calibration, I re-did the S-meter calibration using the XG3,
Thanks Lyle and David. Sounds all's configured OK then. I'll get back to
playing with my K3.

It hasn't always been like this and I'm sure there will be a software fix.
I hope it's on the Elecraft to do list ?

Just a quick question concerning the calibration of the K3 S-Meter and
the use of configuration SMTR MD.
I have calibrated the K3's S-Meter using the manual calibration
procedure (K3 Preamp ON). Everything calibrates fine, but if I try to
use configuration mode, SMTR MD abs as opposed to
Hello,
I am not sure what your signal source is for your calibration and I have not
researched this topoc on this reflector so it may be covered in detail by
others. I will convey what I have found about S meter calibration.
SMTR SC and SMTR OF affect each other so if you change on you have

I get very optimistic readings on my S meter above S9. I calibrated the S
meter on 7MHz as per instructions and everything seemed ok with SMTR OF =26.
According to my calculation 50uV is -73dBm. I increased the input and got the
following readings:-
-53dBm (should be S9+20) reads 9+30 on 6m
This is typical for K3s without the Hardware AGC modification. Mine is like
that and I don't appreciate it very much.

To the issue,
I would think that the hardware AGC intercept (and doing the mod) should
strictly be a performance issue set by Elecraft for engineering reasons, and
that the neat *option* to do S-meter calibration would be to set S9 and the
other major points (S1/3/5/7 and +20/40/60) by raising
I'm not sure where this calibration issue has come from. My K3 has a
very accurate S-meter based on measurements from a Marconi 2018 signal
generator. The firmware is MCU 1.96/DSP 1.73. My K3 has had the hardware
AGC modification done. I have the following parameters and results:

One point I forgot to mention, those trying to calibrate the K3 S-Meter
with the Elecraft XG1 will probably find it difficult. I calibrated my
K3's meter at S9 (-73 dBm) and S9 + 40 (-33 dBm).

In case anyone wants to compare, I just calibrated my K3's S-meter
with an in-cal HP 8640B.The new firmware (Version 1.87/1.69)
includes the magic
S-meter that reads the same no matter what (pre-amp, attenuator,
etc.) and since the firmware documentation said recalibration is
required,
Hi Dave,
I am curious what version of firmware you're running in your K3. My K3 (SN
312) is running the latest firmware (MCU 1.66 DSP1 1.52). I have CONFIG
menu SMTR OF = 024 SMTR SC = 014) with PRE AMP on. As expected my
S-Meter reads S9 with 50uv applied from a XG1 signal generator.
Hi Frank
I too am running MCU 1.66 and DSP 1.52, however I have modified the AGC
as per the hardware AGC modification from Elecraft which may make a
difference. The modification will probably soon be published by
Elecraft. I was sent the information as part of extended testing of ARQ
modes
