QRM Eliminator X-Fase HF Bands Second Generation 1-30 MHz Adjustable Canceller with Integrated PTT C

QRM canceller is inserted from the into the feed line of the antenna without any other modifications to the radio. The box has built-in PTT controls, allowing the eliminator to stay connected during transfer. However, an additional auxiliary receiving antenna is required, such as a 2m antenna or just a few meters of wire in the shed. The two antennas pick up unwanted signals, causing them to be out of phase. The QRM canceller now allows adjustment of the phase angle as well as amplification to cancel unwanted signals before they reach the receiver front end.
