Have you already used the new RBN website (see also Guide to the new website)?
For me, when experimenting in the field (e.g. with different bands, antennas, transmitter power) I find the graphic interface, which can be viewed at a glance, particularly handy and useful.
The map has been available as a beta version for some time and I use it a lot. But it looks now as if it is no longer in beta. It is a very useful resource.
I noticed it a couple of days ago. It’s a great resource.
