[Elecraft] K2 filter attenuation

[Rich Lentz]

Eric:

FL3 is set to 0.50 which I assume is 500 Hz and FL4 is set for 0.25
which I assume is 250 Hz.  Anything narrower than 250 gives to much
attenuation. As I said earlier The attenuation is similar, about 10 db
for either a signal e.g. the 4.000 mhz clock or for a noise generator,
or fairly white antenna noise.  Originally had it set for 0.10 (100 Hz)
as in the table on page 86, but the attenuation was just to much to be
of any use.


Have made the SSB flattening mods, including the latest one with the
added resistor - but they shouldn't affect CW, should they?

Hi Rich,

When you say 'narrowest filter', what bandwidth are you referring to? Is
it
below 400 Hz to 500 Hz?
