Hi,

for those interested, here are two measures of the same x-over, with or without bypass cap only in the UHF part of 2405...(1uF+0.01uF...0.16mH...1.5uF+0.01uF)
what do you think ?

Looks like a difference in noise floor. Did you use the exact same settings for both measurements?

yes, you can see that the levels are the same, only the "pests" have disappeared ...
