[TenTec] notch filter for Eagle?

[Darrell Bellerive]

 From page 43 of the Icom IC-7300 manual 
(http://www.icomamerica.com/en/downloads/DownloadDocument.aspx?Document=787):

"The IC-7300 has Auto Notch and Manual Notch functions.
Auto Notch:    Used in the SSB, AM and FM modes.
Manual Notch:    Used in the SSB, CW, RTTY and AM modes."

How's things out in right field, Rick? :-)
