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.
73, Bill W4ZV
