[Dxspider-support] Long mail/bulletin messages

[Charlie Carroll]

Where in DXSpider do you set the default for number of lines.  I've looked,
but can't find a reference in the docs.  I changed the command in the AK1A
node.dat so that I only send 5 lines to the W1HR node.  At least now I have
the bulletins flowing.  I want to experiment a bit.

Thanks
Charlie, k1xx
