I don't know about your rigs, but My Icom 706, My Ten Tec Omni 1, Yaesu 767GX circa 1980 and my Yaesu FT-2000D all seem to match my K3's S meter reading all within one S unit. That's close enough for me.... This is a Hobby, not an exact science. At least if someone on the air gives me an S3 reading I know approximately how well I'm doing at his QTH given the idea I know HIS antenna set up, and Mine. That's good enough for me. > From: [email protected] > To: [email protected] > Date: Thu, 15 Jul 2010 13:52:29 -0400 > Subject: Re: [Elecraft] K3 S Meter behavior > > > Regardless of the fact that in 1934 (as was indicated to me in off > > reflector email) we used to not use the meter for the S report, at some > > time (1970's when proper calibration and standardizations' came about) we > > were able to shift that OLD antiquated 1934's definition over to a > > STANDARDIZED S meter reading as part of the RST. > > > There may be a "standard" some people believe in, but it is a "paper > standard" that never took hold.
