Hi Barry - the difference is that the traditional cluster network relied
on spots sent manually by individual stations also connected to a
cluster. The RBN, on the other hand, is over 200 nodes worldwide that
do automated spotting. Those spots are forwarded to our central server,
which then sends them to the DX cluster network via Telnet.
Not all DX clusters accept RBN spots, while many have options for each
user either to accept RBN spots or only traditional human spots.
There's more than you'd ever want to know about this on the RBN web
site, which I assume you're already using. You can also look at
dxcluster.info, which has an easily sortable database for determining
what clusters there are and which ones handle RBN spots.

Hi Jamie, I apologize, but know nothing about spotting, at all. What
is the difference between RBN and "Old School Network"? I am familiar
with RBN because I use it to check my signal strength when calling CQ.
But aren't all the spotting networks connected together? Which do most
contesters or N1MM users use? If there is a website that explains all
this, perhaps you can just provide link instead of taking time to
answer. Perhaps it is somewhere in the N1MM manual, as well, and could
provide page.
Thanks very much.

I will echo that, as soon as I started running, I could see I was
spotted by RBN in the INFO window of N1MM......and got some
callers....BUT.....when I got a manual spot on the old school network,
it was almost instant pileup....

ARRL DX CW 2024
Joe (WB9SBD) I thought same as you, but I tried to do selfspot and found
how much it helps.
Not very much old fashioned dudies using RBN telnet spots. They just
looking to DX summit :)
Really!

You should do this test in a Phone contest. I bet the results would be
very different.
In a CW test I do not see any need to self spot at all.
I mean each CQ most likely will be caught by the RBN, and spot you.
And your self spots will be blocked, ignored, whatever ya call it.
Only if you stop CQing and time it just right should a self spot make it
through.
