APF was discussed extensively in August 2009 (check the archives) including a simulation of the exact FT-1000D APF circuit I sent to Al W6LX. It has always been "on the list" but Wayne has now made no less than 3 promises on the Yahoo Groups K3 list in the past few days that "we're working on it". Maybe something will actually come to pass this time!
