QRM Eliminator Box, 1.8MHz‑30MHz Adjustable X Phase Control Aluminum Alloy Canceller, DC 13.8V 150mA Built in PTT Control Eliminator with Dial and Knob
50Ω, 1.8MHZ-30MHZ:The impedance of the QRM eliminator is 50Ω, the frequency range is 1.8MHZ-30MHZ, the maximum transmit power is 100W, the audio connector is RCA (PTT can be connected), the power connector is 5.5*2.1 mm power supply, the power supply voltage is DC 13.8V/150mA.
ALUMINUM ALLOY, PCB:Aluminum signal eliminator is made of aluminum alloy and PCB material, stable and durable, the QRM eliminator plugs into the antenna's feedline from the without any other modifications to the radio, the Qrm eliminator contains the interface circuitry needed to work with most modern HF transceivers.
ADJUSTABLE:The QRM Eliminator now allows the phase angle and amplification to be adjusted to eliminate unwanted signals before they reach the front of the receiver.
PTT CONTROL:The box has a built-in PTT control that keeps the canceler connected during transmission. However, an additional auxiliary receiving antenna is required, e.g. a 2m antenna or a shed with only a few meters of wire. The two antennas receive unwanted signals, resulting in different phases.
WIDE COMPATIBILITY:The QRM eliminator includes the interface circuitry needed to work with most modern HF transceivers for a wide range of uses.
