_______________Product Information______________



Feature:
1. Aluminum alloy shell design, strong and wear-resistant, can provide a long service life.
2. Built-in PTT control can keep the connection status of the canceller during the transmission.
3. The QRM eliminator is inserted into the feedline without any additional modifications required to the radio.
4. The eliminator has a dial and a knob pointer, and the phase can be adjusted through the knob.
5. The QRM canceller allows adjustment of the phase angle and gain to cancel unwanted signals before they arrive at the front end of the receiver.

Specification:
Item Type: QRM Eliminator
Material: Aluminum Alloy
Principle:
The QRM Eliminator is inserted into the feedline from the trx to the antenna without any additional modifications required to the radio. The box has a built-in PTT control which enables the Eliminator to stay connected during transmit. An additional auxiliary receiving antenna is required, though, like a 2m antenna or simply a couple of meters wire in the shack. The unwanted signal is received with both antennas resulting in different phases. The QRM Eliminator now allows to adjust the phase angle as well as amplification in a way to cancel out the unwanted signal before it reaches the receiver front end! It's based on a totally innovative concept and cannot be compared to the normal ”noise blanker” performance.

Package List:
1 x QRM Eliminator  
1 x 3P Power Control Line1 x User Manual

Note:
There is a 0.5‑1mm deviation between the dial and the knob pointer.
