Kenwood TS-940 Roofing Filter Mod
After installing a prototype Inrad roofing filter mod in the Kenwood
TS-940, we believe there is not enough improvement to make any
substantial difference under operating conditions and therefore Inrad
will not offer a roofing filter mod for this rig. We will make
the 45.050 MHz crystal filter
and the Inrad 117 Experimenter
Kit available for experimenters who wish to do further work in
this area. (Apr 25, 2009)

Yaesu FT-847 Roofing Filter
After evaluating the Yaesu FT-847 we have determined that it there is
insufficient physcial space within the chassis of the radio to
accomodate our roofing filter parts.
The 45.705 MHz crystal filter
and
the
Inrad-115 Experimenter Kit are vailable for experimenters who
would like to to create an outboard roofing filter mod on their
own. (Jan 2, 2009)

Kenwood TS-690/450, Kenwood TS-570 Roofing Filter
After evaluating the Kenwood TS-690 we have determined that it is
impractical to offer a roofing filter kit for this radio because of a
variety of physical/mechanical considerations.
The 73.050 MHz crystal filter
and
the
Inrad-117 Experimenter Kit are vailable for experimenters who
would like to give it a try on their own. (Nov 17, 2008)

Yaesu FT-2000 Roofing Filter
After designing and installing a prototype Inrad roofing filter mod
for the Yaesu FT-2000, BDR testing at 20 kHz showed no improvement
while the IMDDR was only slightly improved by 3 dB at the tone spacing
of 5 kHz. We believe this is not enough to make any substantial
difference under operating conditions, and therefore Inrad will not
offer a roofing filter mod for this radio at this time. We will make
the 69.450
MHz crystal filter available for experimenters. (Aug 27, 2007)
