Jack,

That would be OK if the busted spots would stop coming in.  Think of the
wasted bandwidth around the globe that results from this problem.  Adding
to the processing burden of my local logging program is not the answer
when it can be done in the RBN system itself and totally eliminate the
problem.

You have to remember a couple of things:

1) is that these are busted callsigns.  They are copied wrong by the
skimmer systems.  Just because they happen to be wrong, does not mean that
they might not also be a real callsign so a "blacklist" will not work.

2) is that the RBN is not like the human packet network where you could
send a "TALK" message to someone sending out busted spots and tell them to
stop.  The RBN cannot be told to stop making mistakes - and it
continuously repeats the same errors over and over and over and over and
over and over and over and over and over and over and over and over and
over and over and over and over and over and over and over and over.

Get the point?

Error correction in the RBN is the correct solution.
