250 Hz.  There is not currently a 150 Hz available and there probably never
will be.  The roofing filter is not used to determine the receiver's
ultimate selectivity and doesn't need to be that narrow.

Hi there,
I am new to the list and in the process of buying an Orion. I read in an
article about the Orion that the roofing filters where available down to
150 hz. I see only 250 hz advertised. 
What is the narrowest filter available ?
