[Elecraft] KX3 Roofing Filter Question

[Don Wilhelm]

Stan,

I am not going to give you a terse answer, but I can say that the 
sensitivity of the KX3 does not depend on the roofing filter.

However, the roofing filter will give you more rejection of unwanted 
signals that you may encounter in crowded band conditions.

If you do not operate when the bands get crowded, you will not notice 
the difference with or without the roofing filter option.

If you do choose the roofing filter, be certain you do the calibration 
if it is a kit.  If you order the factory built KX3 with the roofing 
filter option, that calibration will have been done at the factory.

73,
