This is a test of the HiPerMite - W1ZY calling CQ on 7013 kHz with strong stations calling a VU (India) station on 7012 KHz. This is a before (Filter in) and after (Filter out). Hear the strong station after I take the filter out. Bandpass is 1.5 KHz with the filter out. The filter narrows thew bandpass to 200 Hz without ringing.
