QRM Eliminator X-Phase (1-30 MHz) HF bands Module Bare Board

Principle The QRM canceller is inserted into the feeder of the antenna from thetrx without any other modifications to the radio The box version not this item has a built in PTT control to keep the canceller connected during transmission However an additional auxiliary receiving antenna is required such as a 2m antenna or only a few meters of wires in a shed The two antennas receive unwanted signals resulting in different phases The QRM canceller now allows adjustment of the phase angle and amplification to cancel out unwanted signals before they reach the front end of the receiver It is based on a completely innovative concept and cannot be compared with the normal silencer performance 1 PCB 73 85 1 6mm2 Weight 55gPackage includes 1 x QRM canceller
