The link is on the allstarlink.org page it is labeled " DIAL RC1 for Raspberry Pi 2/3 (Recommended)"

<-- Hi Steve, Tom and All: Well... the above post from Steve was a huge clue for me!!

I was previously using a different image (http://dvswitch.org/files/DIAL/rpi2_dial_V101.img).... this is the image that was giving me problems with a dual node configuration.

With the image referenced by Steve (the RAT_RC1 image), I was able to setup two full-duplex nodes (using chan_usbradio).

I have rebooted the Pi (3) about half-a-dozen times and so far, the USB numbering seems to be static (no swapping of node #'s).

Great progress for a Sunday night :).

Cheers!
