Re: [TenTec] Omni VI roofing filter JPG

I'm not sure I follow you there Jeff. Having an optional filter on the IF 
board is not required to activate the roofing filter but you still need to 
push either N1 or N2 to make it's relay kick it in line. If you wanted it on 
all the time I suppose you would just feed +dc to one of the control lines 
on the filter which would keep it's relay closed. The filter needs the relay 
even if you have the ssb roofer installed. That way it will still work on 
FM. But of course, who uses FM anyway?
