Re: [Elecraft_K3] K3S 'S' meter Tracking and Calibration?.
S meter cal is certainly a sore point for me. My TS-990S follows no industry standard. Most of the K3 units I have used have been quite good, particularly when in absolute mode. One unit, however, would never cal (owned by K2MLB), and even sending it back to the factory didn't fix it. Most knobbed radios are lucky to have 3 dB per S unit, with many Icom 2 dB per S unit.
On the other hand, SDR radios like Perseus, Flex, ANAN and Elad are spot on. The JA radios have a long way to go in that respect. It will be interesting to see what happens with the IC-7300. Hopefully it doesn't follow their legacy radio S meter calibration.
