Understood. My poorly described point was that the signal strength as reported by the s-meter may not provide a good description of the signal strength you heard which may be influenced by the ?bandwidth? of the signal passing through the meter. Readability can be influenced by factors other than by signal strength.
How wide is the band being read by the s-meter circuit, and can signal strength be influenced by the power distribution within that s-meter band width, in particular by varying the TX or RX equalizer?
