Inrad 352 was a kit to build a 600hz 4-pole roofing filter for the Orion

This one is 4 pole but the crystals are marked (ink stamped) "352" and "500
Hz". It is not "canned" and I was using it in the Omni VI+. It would
probably work in the Orion as a roofing filter. The Inrad folks also said it
was a
600 Hz filter so ... it looks like consensus. I bought it as a "500 Hz CW
filter" from another Ham. Thanks for the feedback.
