  This seems strange to me:

  1) Right now, noise level with 6k/2600 is 3-4 s-units
  2) If I go down a notch to 2.5k/2500 noise GOES UP to 4-5

  Is this observation is consistent across all bands (blankers/notch and such are
  off).

  You'd think it would GO DOWN with a narrower filter combo.

  Going down to narrower settings, I get the expected results.

  2.5k/600 shows 4 s units
  500/500 GOES DOWN to 2

  I believe radios will have different gain settings depending on different
  filters to make up for the insertion loss.

  Anyone else see this effect?

  73!

  Jay
