Several times over the last 5 years INRAD has offered 700 Hz filters
for the k3/K3S. For casual CW operation
something like a BW of around 700 Hz is often just about ideal. I equipped my
K3S with this filter and do use it
from time to time. Something like a 400 Hz or 250 Hz filter is
Note that some of those filters are no longer available and new ones replace
them.

Thanks to everyone who responded to my question regarding crystal filter
shape factors for the K3S. The plots shown on the Elecraft website are a
bit fuzzy for my eyes, but I did find the list shown below from a post
in 2008.
I'm assuming the shape factors are the same for the current b
I thought the shape factor of the 2.8kHz filter was 1.5 to 1 which is
impressive up front with good deep out of band pass rejection in excess of
70 dB. The DSP adds the final shaping to the signal that exceeds the
roofing filter spec and is therefore the most effective source of final
rejection. On
Tony,
The filter shape factor is not stated, but there are filter plots on the
Elecraft website.
The filer shape factor for the roofing filters is not critical as it is
in an analog receiver. In the K3/K3S, the final filter shape and shape
factor is determined by the DSP filters which follo

Where can one find filter shape factor specifications for Elecraft K3S
filters?
Thanks, Tony
