the Receiver wants to download at startup time

The Receiver doesn't download the database at startup time. It grabs it as it needs it.

If you just relax for a week or so, I'm working on something which will eventually include a full protocol description for the Rio Receiver.

Of course, that's in between fitting Jen's new kitchen, which is a barrel of laughs. You don't fancy flying over to London with your workshop and giving me a hand, do you?
