[App_rpt-users] Simplex node

[Kevin Custer]

Kevin,

What are you using for PC hardware?  What's the processor, RAM, etc?  If 
changing from USB to Simple fixed the issue you reference below, I'd say 
you were over taxing the computers capabilities. USBradio is a wonderful 
thing, but only if you have the hardware to support its functionality.

CTCSS is not mandatory.  You can have a carrier squelch repeater, or you 
can have the radio or other device do the decoding and use "CTCSS from  
= usb or usbinvert"
You also need to comment out the proper CTCSS components in the usbradio 
conf file, otherwise CTCSS is automatically "turned on".

Again, the symptoms you speak of makes me believe you are running out of 
horsepower.
