The filter arrived just a couple of days after I ordered it. Installing this in the Omni 7 was quite easy. Remove the cover without shearing the speaker wires, remove two cover screws over the filter box, pop the filter into its 3-hole mount socket, put it all back and fire it up. The filter makes a huge difference to copying CW, and it activates as soon as the BW adjustment is set below 500 Hz. The filter doesnt "ring" or introduce a hollow sound to the receiver. Makes copying CW in a crowded band easy with the Omni 7.
