How to Use

The QRM canceller is inserted into the feeder of the antenna from the without any other modifications to the radio. The box 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, resulting in different phases. The QRM canceller now allows adjustment of the phase angle and amplification to cancel the unwanted before it reaches the receiver front end. It is based on a completely innovative concept and cannot be compared with the normal silencer performance.

Definitely reduces noise without reducing the desired signal. But i should have gotten the version that has a round power button on the left side of the front panel. That version has jacks that are more friendly.

I am a ham radio operator. My washing machine puts out a lot of noise on the 80 mter band. I bought this to try to reduce it. I hooked up the radio and antennas, plugged it into my 13.8 v power supply, turned it on and adjusted the gains and phase, and saw no difference. I turnd it off and on and could still see no difference. It seems to do nothing at all.
