QRM Canceller X Set The QRM Canceller X Set plugs directly into your radio antenna with no modifications to the radio, enabling a straightforward setup. Key benefits - Plug-and-play installation: connects to the antenna without radio modifications. - Effective interference reduction: targets the 1-30 MHz band to deliver a clearer, more stable connection. - Reliable during transmission: built-in control maintains the canceller connection as you transmit. - Requires additional receiving antennas: for best results, use an extra receiving antenna such as a 2-meter antenna or several meters of coax in the shack. - Phase considerations: two antennas may pick up unwanted signals, potentially causing a phase difference that should be managed in setup. Important note - This is a fully innovative concept and should not be compared with conventional attenuation devices. Use scenarios - Amateur HF operation on 1-30 MHz where nearby noise or interference degrades receive and transmit clarity. - Station environments with multiple RF sources in close proximity, improving signal readability with an additional receiving antenna. - Portable or field setups that benefit from an ancillary receiving antenna to optimize cancellation while operating transceivers in restricted spaces.
