We're going to add a final instruction to K3 Utility explaining that SMTR OF and SC must be adjusted after running RF GAIN calibration. I suggest doing this with SMTR MD = ABS, preamp ON. Under these conditions you should be able to set SMTR OF and SC such that 50 uV produces an S9 reading, and 1 uV results in S2 to S3.
Having verified this, you can if desired set SMTR MD to ABS, which is independent of the preamp and attenuator settings. The OF and SC values may need further tweaking in this case. Regarding SMTR MD: It can be set to either ABS or NOR at the time the RF GAIN cal procedure is run. The menu S-meter settings have no bearing on the DSP's internal calibration process. They are only used to set up the S-meter readings per the user's preference. I'm verifying this with Lyle and will get back to you if I'm wrong :) Lyle is on vacation and a bit hard to ready. 73, Wayne N6KR On Oct 7, 2009, at 1:51 PM, O.
