[arm-allstar] CTCSS

Luc,

 First of all don't worry about the simpleusb.conf file itself. It is
automatically created when you run simpleusb-tune-menu, make your
selections there, and then save it. You do not need to edit the
simpleusb.conf file.

The simpleusb channel driver will not decode PL. It must be supplied with a
signal (COS) that indicated PL was decoded in your receiver. This COS level
gets fed to pin 48 on the FOB and then you use item J in the
simpleusb-tune-menu to set if this is usb or usbinvert.

If you do not have PL decode in your receiver you have two choices. Buy a
PL decoder board that would take RX audio and supply the COS signal to the
FOB or use usbradio instead of simpleusb. Unfortunately the usbradio
channel driver does not work that well but it is usable. To use usbradio
you do need to change the channel driver rxchannel= statement in rpt.conf
and setup the usbradio.conf file. There is no script to do this. You need
to actually edit the file.
