Both you and Ed raise good points. No intent there -- I agree that the so-called 250 Hz filter is slightly more useful than the 400 Hz. My real objective is to get Inrad to clean up their act! BUT -- take a look at the data in this link. Lots of food for thought. There's something different about the K3 Sub-RX, and the Roofing filters seem to fall apart below about -25dB. Makes a guy wonder what's going on! http://audiosystemsgroup.com/K3FilterStudy-250HzRoof.pdf 73, Jim K9YC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
