OK my PTT is working but it FOLLOWS the keying, that is the transmitter shuts on and off as a programmed message is sent. I suspect there is a command to insert to close the PTT at the start and release the PTT at the end of a message; however, I have not found it. Any clues? 73 Chas K3WW -- WWW: http://www.writelog.com/ Submissions: writelog@contesting.com Administrative requests: writelog-REQUEST@contesting.com Problems: owner-writelog@contesting.com
