Problems with local QRM on short wave? Very often the answer to this question is a clear 'YES'. Those living in rural areas know how 'clean' the frequencies can be.
However, most interferences are caused by local electronic sources, like TV's, computer, bad connections.
With this
QRM Eliminator you can get rid of local interference up to an S9 level almost entirely; the result is a clean QRG! You don't have to know what kind of a interference is present neither would you have to have knowledge about the location of the interference. It doesn't matter if the interference originates from the own Packet station of from a welder 100 meters away.
The QRM Eliminator is inserted into the feedline from the transceiver 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.
