[TenTec] Roofing filters selection

[Stuart Rohre]

I think if there is only one socket for a roofing filter, it must be as 
wide as the widest signal mode you receive in order to pass the 
modulation for all modes.

If there were multiple sockets I guess it depends if certain roofing 
slots are selected by the same button as certain IF filter slots, so you 
would have FM filter in one position, SSB in another, and CW in last 
slots that are linked.  Maybe someone who has more recently read about 
roofing filters can chime in.
