Re: [App_rpt-users] URI active low?

Being pulled low enough is kind of what I was thinking and wondering if others have had that issue. Its really the only thing that makes any sense to me in terms of what I am experiencing. A little digging shows this solution, which I will try this weekend once I dig out my parts. http://dmkeng.com/images/HIGH_CURRENT_PTT.pdf

I seem to recall some people having issues with the PTT output not being pulled low enough, you might try searching the list archives for a similar situation. I recall several fixes from adding a reed relay, inserting a diode in line, or using a transistor buffer, might have been a jfet.
