Many of the DX stations I have worked for "new ones" would have been totally inaudible if my noise floor had been an S-unit higher. Both my present and former MFJ-1026 units had the high noise floor. As noted in my post about filters and IMD yesterday, the solution is to use a preamp ahead of the noise canceller. You need to feed it high enough level from the antenna such that you hear/see no increase in noise when the unit is engaged. 73, Paul N1BUG _______________________________________________ UR RST IS ... ... ..9 QSB QSB - hw?
