Many thanks to all who provided their suggestions. I decided to try Joe's (W4TV) suggestion and elect RTS. That appears to have solved the problem of the transmit staying on.
My only remaining problem is a 100 to 200 millisecond spillover into the next sequence. I have synched my Mac to time.nist.gov <http://time.nist.gov/> and the time.is <http://time.is/> site shows that I am dead on. If anyone has any suggestions, they would be much appreciated. 73, John WA1EAZ > On Jan 13, 2017, at 1:53 PM, Guy Olinger K2AV <[email protected]> wrote: > > Can't argue entirely with success, but often folks just want to put the > trouble In a cage so they can get on with having fun.
