Bill, At present I do not know of any provision for bringing out a hardware bit that is active only when the TUN button is pushed. Sounds like a good idea for a feature request. Possibly the ability to reassign one of the 3 TX outputs for this function. That would be simply a software change, no additional hardware required.
In the meantime a possible work around would be to set the tuner for fully automatic, tune, and then set the tuner for semi-automatic. 73, Ray, K9DUR _______________________________________________ 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.flex-radio.com/ Homepage: http://www.flex-radio.com/
