Description

Aluminum shell, front and rear baffles are: epoxy glass fiber board FR4. 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.
