[aprssig] Linking digipeaters

[Cap Pennell]

I know I'm not the only one whom would still like to know just exactly which
firmware versions of the TNC are involved with these IGating delays, and
which other firmware versions are completely innocent.

I hope this can be learned, too.  And I think it (specific firmware version
evidence) could be useful info to provide to Kantronics toward a resolution
also.
