[TenTec] Inrad #352 650 Hz Roofing Filter Kit

[Bill Tippett <btippett@alum.mit.edu>]

        I updated my website with some background on the #352 kit
as well as the recent measurements by Sherwood Engineering.  For
$40, you can significantly (~10 dB) improve Orion's already outstanding
front-end performance at 1 kHz spacings.  For me, having the world's
best strong-signal handling receiver makes the color display issue pale
by comparison (sorry I couldn't resist the pun).  ;-)
