Hello I do have a QSK-5 in my AL1200x which worked fine so far with my Kenwood TS-870S and the Elecraft K2 transceivers. Recently I got a TenTec Omni VI+ and I do have problems interfacing the QSK-5 by using the Omni Vi+ handshaking TX OUT/TX EN. Can somebody give me a hint how to do it correctly? Thanks Gert, OE3ZK
