Re: Alternative(s) to 200 Hz CW Filter

Roelof Bakker

Hello Markus,

No problem:

You need to register to be able to use it.

Alignement of a 10 Hz filter is a bit challenging as the adjustment frequenccies must be set
to 0.1 Hz. I used a sound card based generator. However wider filters are less demanding in
this regard.

I used the Bessel filter function for best phase response = no ringing.

If you like I can sent you more details etc. direct.
