OK. Thanks for that. I'll see whether I can use that in the Obs as a way of getting around the bottleneck. I can't use it between Obs and house because they're on different switchboards altogether. Pity.
I'll report back on this. It's interesting as well as a bit challenging for me. I was once very computer literate but systems have overtaken me and now, I'm back among the Luddites.
