Built in PTT Control: The aluminum alloy QRM eliminator has a built in PTT control that keeps the canceller connected during transmission.
Easy to Use: Aluminum alloy QRM eliminator is inserted from the Transsmite Receive Unit into the antenna feedline without any other modifications to the radio.
Adjustment: Aluminum alloy signal canceller now allows adjustment of phase angle and amplification to eliminate unwanted signals before they arrive the front of the receiver.
Auxiliary Antenna: The QRM eliminator requires an additional auxiliary receiving antenna, such as a 2m/6.6ft antenna or a few meters of wire in a shed. The two antennas receive unwanted signals, resulting in different phases.
Wide Compatibility: The QRM eliminator contains the interface circuitry needed to work with most modern HF transceivers and is widely available.
