The new upgraded version of 2021, TX LED indicator is added !

principle:

The QRM canceller is inserted into the feeder of the antenna from the trx without any other modifications to the radio. 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 wires in a shed. The two antennas receive unwanted signals, resulting in different phases. The QRM canceller now allows adjustment of the phase angle and amplification to cancel the unwanted signal before it reaches the receiver front end! It is based on a completely innovative concept and cannot be compared with the normal "silencer" performance.
