KD9SV Products SV-DXSS DXpedition Receive Antenna Switches
KD9SV Products SV-DXSS DXpedition Receive Antenna Switches are the ultimate unit for the active low-band DXer. They combine their legendary Front End Saver with the 80/160 Variable-Gain Preamp, a Four-Position Receive Antenna Switch and a high-speed Solid State Amplifier Keying Interface, all into one easy-to-use package. Originally designed for DXpeditions, they are sure to be on the wish list of all low-band DXers! DXpedition Switches were built to be connected to transceivers that ARE equipped with receive outputs and inputs, and to the transceiver's amplifier keying line. DXpedition Receive Switches will directly key all late-model RF power amplifiers. They include a heavy-duty relay for receive antenna disconnection and transceiver RX ANT INPUT grounding, giving your transceiver the ultimate in front-end protection. The four-port antenna switch allows you to select from different receive antennas and the variable-gain control adjusts for 10 to 28 dB preamplification with dual-band band-pass filtering. This lets you choose, on the fly, the correct antenna and gain combination for optimal signal-to-noise for changing band propagation conditions. You may also bypass the unit when you are operating on the higher bands or to listen to the low band transmitting antenna. KD9SV DXpedition Receive Antenna Switches include the Front End Saver, with a lightning-fast solid-state amplifier keying system that is full break-in CW (QSK) capable for all modern amplifiers. They can handle legacy amplifier positive DC voltage keying lines up to 500 Vdc at 8 A. However, DXpedition keying circuits will not work with amplifiers that have negative DC voltage keying lines such as the Heathkit SB-200, Yaesu FL2100-B or Collins 30L-1. For these and other negative DC voltage keyed amplifiers, pair these DXpedition Switches with KD9SV Products SV-KR External Keying Relays. Whether you are a DXer, contester, antenna experimenter, or just want easy access to multiple receive antennas, KD9SV Products SV-DXSS DXpedition Receive Antenna Switches will organize your station as never before!

KD9SV Products SV-BPF 160 Meter Band-Pass Receive Filters
KD9SV Products SV-BPF 160 Meter Band-Pass Receive Filters are exactly what you need if strong local broadcast stations create an overload condition in your receiver. This often occurs when using separate receive antennas such as Beverage, Loop, Active or long-wires. KD9SV 160 Meter Band-Pass Filters will pass 1.8 to 2.0 MHz signals with a mere 0.5 db insertion loss when terminated with 50 ohm source and load impedances. Broadcast band rejection is as follows: * 0.5 MHz ~60db attenuation * 1.0 MHz >45db attenuation * 1.5 MHz >20db attenuation Don't let nearby AM radio stations keep you from enjoying 160 meters! Order one of your own KD9SV SV-BPF 160 Meter Band-Pass Receive Filters from DX Engineering and get the most out of Top Band!
