[Xastir] Using Xastir online

[Phil]

Regarding my previous question, I think I now have a suitable map. 
Online/OSM_tiled_fosm.geo seems to be what I need.

Now that I have a suitable map I'd like to see some stations displayed 
and since I don't have access to a repeater or a suitable HF aerial I'd 
like to connect to an online site of some kind. I have selected Internet 
server "rotate.aprs.net" from the Interface list. It's up and running 
but nothing is displayed so either I've made an error or I need to 
connect to another site.

I'm running low on solar power at the moment (we live in a motorhome), 
due to murky weather, and so I cannot spend too much time on the 
Internet searching for an answer.
