I would expect this to be a breach of the terms of service for the common online call databases. Like most information web sites, they exist to sell targetted advertising and their callsign database is commercially valuable. Google maps is probably OK, as you would still allow through the Google advertising. Note that there are mapping sites (specifically www.openstreetmap.org) that have a funding model similar to US National Public Radio, and moreover aim to produce royalty free map data, but I'm not so sure that it would be easy to set up a callsign database on that basis, except possibly for the USA, where the data is possibly condidered public domain due to being obtained by a federal agency. The actual software could be rather simple, although a GUI interface would compromise that. The real issue are the geographic and callsign databases. Incidentally, logging in is valuable for advertising funded databases, as it makes it easier to target advertising at individual. -- David Woolley Emails are not formal business letters, whatever businesses may want.
