New from INRAD – model DCA Antenna Disconnect Actuator

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. $99.95. Details on the Vibroplex website (parent of INRAD) at www.vibroplex.com

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.

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)
