[arm-allstar] Help - COS Question

[Jeff Young]

I have found that I cannot get the COS function work properly. I am using a
URI USB interface and GM300 with PTT, Aud In, Aud Out, & Gnd as described in
URI's cable diagram. With the CosFrom set a usb-invert I get no COS activity
on the view screen when the radio is receiving and if I change CosFrom to
USB, the COS is continually keyed. What am I missing?I can go to a hardwired
COS with the GM300 but I have another application that won't have a COS
signal. Any siggestions.

Thanks & 73
