Rich, Usually, the s-meter samples the signal at the final IF so most of the IF filtering will reject signals off-frequency. Since "normally" this is done before the detector stage, audio bandwidth characteristics (what the equalizers affect) are not involved. But I must disclaim knowing anything, in particular, on how the K3 does it.
So you are correct that bandwidth can be a factor it usually is not. But if there is a 1.5 kW station down the block that is 10-KHz off frequency, you will certainly hear him and see it on the s-meter. Again, that is based on normal ham radios and not the K3. Some of the reports of multi-station operations in field day indicate the superior performance of the K3. If you do not hear a signal you should not see it on the s-meter. 73, Ed ----------------------------- Message: 39 Date: Fri, 16 Jul 2010 07:30:34 -0700 From: Richard Hill <[email protected]> Subject: Re: [Elecraft] K3 S Meter behavior To: The Smiths <[email protected]> Cc: Elecraft Reflector <[email protected]> Message-ID: <[email protected]> Content-Type: text/plain; charset=ISO-8859-1; format=flowed 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?
