[Elecraft] K4 S-meter characteristics

[Volker.Debus at t-online.de]

Well said, Brian. A calibrated S-meter may be helpfull for side-to-side on-air equipment comparisons (e.g. antennas) and not for contest business. From time to time you will even find a few people fighting the 20dB HF to VHF/UHF offset....

Real- world VHF transverters do need slightly more than 20dB rx coversion gain (abt 25dB), so an "transverter s- meter  correction" would be highly appreciated for the K4.

My ANAN SDRs do have it, my K3 not....

The International Amateur Radio Union (IARU) Region 1 agreed on a technical recommendation for S Meter calibration for HF and VHF/UHF transceivers in 1981.

Why go back to 1947?
