Re: [TenTec] Orion Notes, High/Low Cut

Carl,
Tnx for the explanation.
Ur info on this reflector has been very helpful to me. And tnx for ur 
response to this high/low cut question.
But how abt the push button effect?? Have u picked up on this?
The effect is like flipping a light switch. Maybe i'm pointing out 
something which everyone has already discovered. Either way, it makes one 
heckuva difference when qrm comes alongside me. It is much more useful than 
merely closing the appropriate high/low cut cut filter.
