The Omni 6 uses a 15 khz filter at the beginning of the 9 mhz IF. In the
manual, TenTec refers to it but does not call it a roofing filter. The
roofing filter hype didn't begin until the Orion. So lots of rigs had these
filters including the TS-870, TS-2000, IC-756Pro, Jupiter, Pegasus etc. etc.
but not until the Orion was it an issue. Now all the sudden everyone thinks
the roofing filter is a new invention.
