Hey now, I've yet to see a rig that is 6 dB an S unit:
Look at the R4C, the scale is 5 dB.
Same for the Collins gear. The scale is drawn and clearly marked at 5
dB per S unit. (Top dB scale... 20 dB absolute is S-5, 40 dB absolute
If I do a factory spec S meter alignment on my Yeasu, it winds up
3-1/2 dB per S unit mid scale.
My 751A's are all over the place, from 2 dB to over four dB per S
Sooo.. Where the heck is it written an S unit is some kind of 6 dB
scale standard? S stands for sorta, not 6. One company proposed a 6
dB standard after WW II, and no one ever adopted it. Here we are in
1998, still trying to use it!
