DIY QRM Eliminator Kit X-Phase (1-30 MHz) HF Bands

Principle The QRM canceller is inserted from the trxinto 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 such as a 2m antenna or a few meters of wire in a shed 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 It is based on a completely innovative concept and cannot be compared with normal silencer performance ① PCB 73 85 1 6mm ② Weight 58g Package included 1 x DIY QRM Eliminator Kit
