New
from INRAD – the DCA2 2 radio / 2 antenna disconnect actuator
On
the heels of the earlier version for 1 radio and 1 antenna, INRAD now
introduces DCA2 – allowing 2 radios and 2 feedlines to be
connected to the same unit. Prevents static discharge, surges, and
lightning-strike effects from damaging your radio and associated
equipment. The DCA is installed at the output of the transceiver,
amp, or tuner in line with the antenna. Plug the DC cable into +12VDC
(ideally from the transceiver). When the transceiver is powered on
and +12VDC is present, the antenna is automatically connected. When
DC is off, the antenna's signal and ground are shorted together and
grounded and both are disconnected from the radio. 1500 watts power
capability, 1.8-50 MHz. DCA1 for one radio and one feedline $109.95.
DCA2 for 2 radios and 2 feedlines, $189.95 Details and operating

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)

is now in stock and ready to ship. Many thanks for your patience!
(Dec 8, 2008)
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)

16, 2007)
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)
Kenwood TS-950 Roofing Filter Mod

Roofing Filter Mod. This mod works for all version of the Kenwood
