Sorry - 3. 3 separate simplex radios. 

Someone else individually replied to me and said it's likely an issue with SimpleUSB and I should try using usbradio instead. I will be trying that tomorrow, but still open to other suggestions. 

Thanks again,

Obvious question - how many is "multiple"?

Hello,

  I am running into a fun issue with DIAL using multiple URIx's on a RasPi 2.

  The issue is that we have a variable delay between the radios. Sometimes the delay is virtually non-existent. Other times, the delay is almost 2 seconds. There is nothing else running on the RasPi.

  I have a number of theories, including that this is a USB delay issue.

  Anyone run into this? Or have an idea how to work around it?

Thanks and 73,
