Principle:
The QRM canceller is inserted into the feeder of the antenna from the trx without any other modifications to the radio. The box has a built-in PTT control to keep the canceller connected during transmission. However, this requires an additional auxiliary receiving antenna, such as a 2m/6.6ft antenna or only a few meters of wire in the 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 normal muffler performance.
