Features: 1. Convenience: The QRM canceller is inserted from the into the feeder of the antenna without any other modification to the radio. 2.PPT Control: The box has a built-in PTT control to keep the canceller connected during transmission. However, an additional auxiliary receiving antenna is required, such as a 2m antenna or only a few meters of wire in the shed. The two antennas receive unwanted signals, resulting in different phases. 3. Adjustable: Allows adjustment of the phase angle and amplification to eliminate unwanted signals before reaching the front end of the receiver! It is based on a completely innovative concept and cannot be compared with normal "silencer" performance. 4. Material: The material is excellent, the shell material is aluminum shell, and the front and rear baffles are: epoxy glass fiber board FR4.
