[Elecraft] Roofing filter for CW

[Olli Tuppurainen]

One thing to remeber is that if you get strong signal within your roofing
filter passband you will notice that AGC will go up to protect DSP
overloading. Then you have use for narrower roofing filters.

I have 400Hz but considering to add 200Hz after working couple of CW and
RTTY contest on 40 meters :)
