I did get in touch with one of the guys who runs strike star but he wasn't very keen to give me raw access to the corrected data from their network. I run Linux so his client isn't much good to me, however I might contact him again down the track and just offer to contribute my data anyway if we can agree on a suitable data format.
However a network of these things certainly would be very useful. Maybe down the track I'll be able to get hold of another one of these units, and try to find a suitable site 100-200km away. Actually it looks like there's one in Uralla, maybe I should get in touch with the guy who operates that one.
Regards,
Dave
