uuencode is good because it is a very widely used standard, but
there is also 7plus, which was designed specifically for radio
mailboxes - it uses the usual 7bit characters and some additional
ones which are handled transparently by virtually all systems.
It can also split files into smaller chunks which may be easier to
handle as mail messages.
Probably the best feature is its efficient correction mechanism -
each line has a checksum, so the decoder can detect lines that were
corrupted somewhere during transfer, and will automatically generate
an error message containing corretion requests which can be mailed
back to the sender, who can then run 7plus on it and automatically
generate a "patch", i.e. a correction file, so that only the
corrupted lines have to be retransmitted.
Give it a try - it should be available in the ham directory on sunsite.
