Hello Brian, Since DDUTIL uses only four of the eight available data lines of the parallel port interface to control the amplifier band switching relays, so you can tell DDUTIL to "talk" to the other four data lines and connect them to a second BCD-10 interface and let it control something else. > Two remaining questions. > > 1 I'm using flex 1500 with (currently) amplifier switching from a slave > relay from the flexwire port ptt.

After all, with the F5K, you take the amp key signal for the amplifier from the jack on the back of the F5K, which would be virtually the same thing as the Flexwire port. > 2 Is there any way to get the PowerSDR tune button to send a signal to one > of my auto ATUs (LDG) to tune, and then to accept a signal back > from the atu > once it has found a match. I suspect it can be achieved with a macro in > DDUtils. Usually the amp key line is routed through the ATU which decides when to tune. Before it does so, it breaks the amp key line and routes the driver power to the ATU, which then tunes and when tuning is complete, reconnects the amp key line. That requires that you manually key the radio, wait for the tuner to cycle, then unkey the radio. AFAIK, there's no way for PSDR to "see" the tuner. 73, Ralph W5JGV - WD2XSH/7 _______________________________________________ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archives: http://www.mail-archive.com/flexradio%40flex-radio.biz/ Knowledge Base: http://kc.flexradio.com/ Homepage: http://www.flexradio.com/
