Thanks for the info Bill,
That puts my mind at ease knowing that what I observed (below) is normal
given the current state of firmware development. No problem, I'll just wait
for the future firmware correction. By the way, my rig has the HAGC
hardware mod installed.

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.
However, when tuning in local broadcast stations, which are S9+50 db on
three other receivers, my K3 only reads S9+20 db. In addition, if I turn
my RF Gain Control fully counter clock wise (anti clock wise) the S-Meter
only reads S7 rather then full scale.

So the question is: am I the only one who has an S-Meter response as
described above?
Thanks for any input,

Hi Frank,
I'm on the Field Test team so I'm using 1.67/1.53. I've also made the
Hardware AGC Mod G4AON described. Using the XG1 and Preamp On (following
the manual S-Meter calibration procedure on page 48), I get SMTR OF = 030
(at the upper limit of adjustment) and SMTR SC = 014. I'm also
experiencing
the same issue you are with RF Gain full CCW resulting in only S7 on my
meter.
Only one other Field Tester (W0YK) responded to a query about my odd SMTR
OF
reading and both of his units were 22/14 and 24/14, which leaves me
wondering if there is something wrong in mine. You comments make me think
I
may not be the only one with some sort of problem.
For other K3 users ***who have actually followed the S-meter calibration
procedure in the manual***, please send me your settings for SMTR OF and
SMTR SC. I'll compile a list and post the results here. If you just used
the recommended settings of 24/14, there is no need to reply.
