[App_rpt-users] Issue with Hangup after first keying

Wow that is it!

My rpt.conf did not even have a duplex setting in it so I had no idea that
it needed to be set. Grrrrr

Seems to be working much better now.

Thanks!

For a simplex node be sure that you have the following defined in:

/etc/asterisk/rpt.conf

duplex=0 (for no telemetry / messasges)

or

duplex=1 (enables telemetry / messages / courtesy tones)

This is a different setting than the duplex = in your usbradio.conf file

N5ZUA
