[App_rpt-users] Radio TX / RX oscillation and APRS questions

[REDBUTTON_CTRL]

The App_rpt default is a duplex value of 2 (full duplex) even though it 
might not state that in rpt .conf. This seems to be the situation for 
new default files created by the ACID install process.
If the config files are downloded from the Allstar server then I think 
it sets a duplex value in the RPT.conf based on what you set up the 
server to be on the website.

So if you connect a simplex radio witht he acid default files, you will 
need to either add the line in the node stanza duplex = 0 in 
rot.conf,**/_and_/ you also must state the duplex setting to 0 in the 
usbradio.conf file as well.

see below:

In rpt.conf:

> [1234]                    ; Change this to your assigned node number
>
> rxchannel=Radio/usb1234
> duplex=0                ; set to half duplex

and in usbradio.conf:

> [usb1234]
