All: It looks like the new Icom X3 is intended for the commecial market, but while looking at a photo of the rig, I noticed it has a built-in PSK decoder like the IC7800.
Assuming it is a PSK31 decoder, and not some other commercial mode, it seems strange to offer it on a commercial transceiver. See it here: http://www.onjapan.net/2006/hamfair/img_1984.jpg Tony KT2Q
