Thanks for letting us know. My Pi just came in today so I was going to test your fix out tomorrow, can that idea. Just as well as I think aprx is having problems also in its latest version. I'm swapping out the uSD card and going back to older versions of everything tomorrow instead.

Folks: I have done more testing on this "fix" to AX.25 networking, and it
is broken --- it works for transmit, but not receive. I will not be merging
it upstream, and if you were planning on giving it a whirl, don't bother.
I've deleted the branch on which the fix lives, and instead opened a
"help-wanted" bug report.
