A little here, a little there
Worked up a nice little mobile setup that you can plug in and put together in about 10 minutes in a garage. Nice little case, a laptop with WiFi, a tripod and an antenna. Just throw it up in someone's living room, set the tripod up on the deck and plug it in.
Worked great. A signal check had us covering pretty all of town very nicely (helps to be up high on a hill, if you can swing it).
I think this is how to do it. Totally mobile setup. Fixed for a single session in someone's house, a few hours, an evening maybe. Then, down for, however long, then, back up again when everyone's in the mood.
It's good, I like it.
