If things are working well using DSP, then why would you want to change them up, unless you want to use a slower computer that does not have the horsepower to do DSP?

In /etc/asterisk/usbradio.conf change the line that currently reads:
 carrierfrom=dsp to read carrierfrom=usb or carrierfrom=usbinvert
The "usb" setting is for COS active HIGH (+5 VDC) and "usbinvert" is for active LOW, which would pull the line to ground when active. In the LOW situation, use a volt meter to make sure there is voltage present to be able to be pulled down. You will also need to change the line that reads:
ctcssfrom=dsp to ctcssfrom=usb if you have a separate line for CTCSS detection. Some radios, like the GM300, let you put both the cos AND ctcss on the same line. In that case, set ctcssfrom=no to ignore it.

How can I trigger the Allstar receiver when it gets a voltage from COS or switch 3 on the fob?

 Does it automatically trigger when a voltage is there? 

I added 5v to the COR URIx and did not get any trigger and I also tried closing SW3 on the home brew fob. Am I doing something wrong?

I will be getting a COS out on my radio and want to use The CTCSS on the radio instead of in AllStar.


Thanks
