manual, TenTec refers to it but does not call it a roofing filter. The
roofing filter hype didn't begin until the Orion.

        If you call outstanding IMD and BDR performance "hype", that
began with Sherwood's introduction of the 600 Hz roofing filter for the
R4C in the 1970's.  I don't call that hype.  I call Icom's use of words
for the 7800 like "unparalleled, astonishing, ultimate, Masterpiece" and
pseudo non-qualified "specs" like "+40 dBm IP3" and "110 dB dynamic
range" hype.  "Hype" implies something beyond truth and facts.
