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 eliminator allows adjustment of the phase angle and amplification to cancel unwanted signals before they reach the receiver front end.
