QRM Eliminator X-phase 1-30MHZ HF Bands Amplifier Parts Kit Finished product

Description

The QRM canceller is inserted from the trx into the antenna's feeder without any additional modifications to the radio. The box has a built-in PTT control that keeps the canceller connected during transmission. However, an additional auxiliary receiving antenna is required. The two antennas received unwanted signals, resulting in different phases. The QRM canceller now allows adjustment of the phase angle and amplification to cancel unwanted signals before they reach the receiver front end!
