The original way that we used was in the receiver after the P25 frames were received and reassembled they were encapsulated and written to the Linux TUN/TAP interface. When properly configured, this interface (typ. 'tun0') shows up as a standard interface in ifconfig (and in the list of allowed network interfaces that wireshark can listen on).

Then later our repeater stuff added support for writing received frames to UDP, using UDP port 23456. See file repeater/src/python/usrp_rx.py.

In response to this, Mike added a UDP option to the wireshark plugin - see this message:
