[CW] NM0S - HyperMite 200 Hz Audio Filter - NO RINGING!

[Walter - K5EST]

This is my follow up meeting on the subject.

Had breakfast with Dave Cripe - NM0S, design engineer on Friday morning at
Ozarkcon Conference.

Dave says "yes" the center frequency can be lowered to 400 Hz but be aware
some parameters will also change. Dave is really busy until after the
Dayton (Zenia) Ham Convention.  Dave, is also President of the QRP ARCI so
he is booked with many challenges right now and cannot do testing to help
with the component values for the change of center frequency.

There was a spreadsheet published but until I get to the QTH and off of the
cell phone I cannot lookup any older files.

73,

Walter Dufrain - K5EST - QRPcw
