[aprssig] TNCx TCP/IP over radio

[Andrew Rich]

Anyone got suggestions on point to point and payloads ? 

For 1200 baud channels that are shared with other packet users, an mtu value of 256 is reasonable; in fact, since that is the largest packet size most non-TCP/IP ham networks (like digipeaters and NetRom) are designed to handle, 256 is the largest mtu you should specify if any of your packets are going to travel via such a node.
