Brian, What is in the isolation box? I'm always looking for ways to do the control keying and changeover functions.
As far as repair of the ULN2003A goes, I recommend sending the SDR back to Flex as it is all surface mount stuff on the board. They are skilled, reasonably priced and fast. Three out of three is good! Just had my SDR-1000 in for upgrades and repair. 73, Larry K2LT Brian Sherrod wrote: > Thanks for all the replies on this.

By then it was too late, and it quit keying. _______________________________________________ FlexRadio mailing list FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archive Link: http://mail.flex-radio.biz/pipermail/flexradio_flex-radio.biz/ FlexRadio Homepage: http://www.flex-radio.com
