Is it possible to connect the KX2 to a KXPA100 amp and an MFJ-1708SDR TR switch? Do I need a Y adapter to split the PTT for the KXPA100 and 1708 TR switch? I want to use the RSPDuo as the receiver on the same antenna as the KXPA100. 73 Larry HB9EYQ -- Sent from: http://elecraft.365791.n2.nabble.com/
