[App_rpt-users] Simplex node problem

I have a simplex node setup with a Baofeng 888. I receive ok (the periodic automated date and time) but when I transmit a command, I just hear a beep. On the Node Status page the "Total Keyups" increments each time I attempt to send a command. However, the "Total Commands Executed" remains at 0. "Total Timeouts" is also 0. It's as if the command is being received but not interpreted correctly? Any ideas? Thanks, Jay KI7SOX
