[Elecraft] K2 -- is this normal?

[Matt VK2RQ]

Sound strange. Do you have the SSB module installed, and have set FL1 to OP1? In that case, when you switch from FL1 to FL2, you are changing from the crystal filter on the SSB module to the crystal filter on the main RF board. Maybe if there is a problem (eg bad solder joint, component in wrong place) on the SSB module, then maybe this is why you observe a difference in the volume?

I'm more curious than concerned, using CW, I notice when I go from FL1 to FL2 my general "noise level" seems to go up to the point I need to turn down the volume -- is this normal behavior? I would expect the noise level to go down as the filtering gets narrower?
