That's the "cafe digi" syndrome.   We've often met and played radio in
cafes.  Getting packets out via a mobile digi has been easy.  Getting them
back in to a marginal portable station has been very problematic.  We get
out but don't hear the replies.

My solution - add WIDE2-1 to the TEMP1-1 and WIDE1-1 (and mycall) settings
of UIDIGI.  That'll bring in some of the packets from the wide area nodes
and since it's already the end-gate of the packet path, it won't affect
the network routing outside of a few extra packets.  Fortunately it's very
easy to change the UIDIGI setting of a D700 (or set up a separate PM for
it) so this can be quickly turned on and off.

More Packets!
