Is now an ok time to point out that 3db of signal on any receiver
S-meter is about the width of the needle? The 1.6 dB loss between 8X
and 58A is almost impossible to see on any S-meter you'll ever see.

It's why we boost power in 10-20 dB increments on ham radio. You are
hard pressed to see any difference between 25W - 4.5 dB and 25W -
6.1dB actually on the air.
