[App_rpt-users] CTCSS decode in software?

[Chuck Henderson]

It is working now with "rxctcssoverride=0"
I had read in the chan_usbradio.c file this comment...
 ; rxctcssoverride=0     ; default condition to not require rx CTCSS
That is why I had "rxctcssoverride=1" in my config file thinking it
would change from the default of not requiring CTCSS, to requiring
CTCSS.
Then after the first time I tried "rxctcssoverride=0", it still didn't
work but after another reboot of the system, then it does work.
Apparently "rpt reload" and "rpt restart" do not re-read the
usbradio.conf file for this option to take effect but a system
"shutdown -r now" did.
Thanks for the help
Chuck
