Re: [TenTec] OMNI VI/VI+ Roofing Filter Mod. vs NB Function and FM/FSK Mode Operation

[Clark Savage Turner <csturner@kcbx.net>]

Thanks for the info regarding the NB, Dave.  I think you pioneered (I 
recall some early correspondence with you on this!) the roofing filter 
ideas for the OMNI VI.  I appreciate it.

One note to this (especially to new guys), the Inrad mod itself does 
NOT render FM or FSK inoperative.  If you don't engage the Inrad 
roofing filter by pressing the NAR button, FM and FSK are fine, since 
you allow the wider roofing filter to stay in line.  The NAR button 
selects and deselects the additional narrow roofing filter according to 
your preference.
