Guys,
If you want to know what your S-meter really reads build the attenuator
in the ARRL handbook and inject a fixed signal. I did this when my quad
was showing much too much F/B and gain.
This table is for a TS-450 on 20m and slightly ambiguous due to the #$@
leds instead of a real meter.
S-METER READING DB ABOVE 0
0 0
1 4
2 9
3 13
4 16
5 19
6 20
7 22
8 25
9 29
9+10 36
9+20 46
9+30 64
As you can see, it is anything but 6 db per S-unit. Over some of the
range is is 3db/S-unit. I don't have a calibrated voltage source so I
can't say how many mv S9 equals.
With this info, the quad appears much closer to theory.
