Setting up a telnet cluster is the step operators get stuck on. The
address and the port are two pieces of information nobody has to hand,
and a typo in either looks exactly like a node that is down — there is
nothing to read, only a connection that never comes.
So the editor offers a list, and choosing one fills the fields. Six to
begin with: F4BPO, DXFun, SOTA, POTA, and the two Reverse Beacon feeds —
listed separately and named for what they carry, because they are one
network on two ports where 7000 is CW and RTTY and 7001 is FT8 and FT4,
and no amount of trying will tell you which is which.
The preset then gets out of the way. Everything stays editable, the name
is only filled when the operator has not chosen one of their own, and a
node typed in by hand behaves exactly the same. Reopening a node created
from a preset shows it selected, so the list also answers "which one is
this".
