With little activity and every transmission an experiment in the unknown, that's of little consequence. If ever there was enough activity, an option might be to put up a website where transmissions can be notified in advance so that receivers could be prepared. A transmission could be announced through the site and successful decodes reported against it. That would give a public log of activity and performance. -- Paul Nicholson --
