Function:
1 With the QRM canceller, you can adjust the phase angle and gain to cancel unwanted signals before reaching the front end of the receiver.
2. Built-in PTT control and built-in PTT control keep the cancellers connection status during transit.
3 Very convenient to use, the QRM is inserted into the feedline without adding additional modifications to the radio.
4 Dial and knob pointer, there is a dial and knob pointer, and you can adjust the phase using the knob.
5 Made of high quality aluminum alloy shell design, durable and wear-resistant, excellent performance and long service life.
How to use:
The QRM canceller is inserted into the feeder of the antenna without any other modifications to the radio. Box incorporates PTT controls to keep the canceller connected during transit. However, additional auxiliary reception antenna, such as 2m antennas or a few meters of wire in a shed. The phase is different because the two antennas receive unnecessary signals. QRM cancellers can adjust phase angle and amplification to cancel unwanted signals before reaching the front end of the receiver. This is based on a completely innovative concept and cannot be comparison to standard
