The filter width is important but not his problem. He reported that he has no LINE IN gain. (RF out zero) Filter width for Pactor 1+2 is 500Hz, center on 1500 is default, but can be adjusted in the Ptc-2 (tone setting 4 will set the tones to 1400 - 1600Hz) For Pactor 3 the full SSB bandwidth is needed, so set the filter to 2400. Center is 1500Hz by default. (again tones 4 - which is set by Airmail and cannot be changed) 73! de Werner OE9FWV -- I'm not a complete idiot - several parts are missing.
