Thanks for the wonderful and helpful description of how to set things up. I'm also about to interface a homebrew amp (AN762 with an external switched filter box-- switching still to be finalised) with my flex1500. I gather from the links above that I can control the filter box (and antenna switching) via the paralell port and DDUtils which I already have installed. I had been wondering how to use it for HB amplifier switching. Two remaining questions. 1 I'm using flex 1500 with (currently) amplifier switching from a slave relay fromn the flexwire port ptt. Is there any need to alter this, does it affect so2r ampkey setup? This is also probably relavent to the OP. 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. -- Brian Duffell G3VGZ _______________________________________________ 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/
