You won't be able to do configuration and setup if that is a windows program but MacLoggerDX should be able to communicate through the same USB/Cable that you use on windows provided that you load a Mac OS X driver for it.

Up to 8 rigs actually.

It's pretty straight forward. There is a popup in the Radio Prefs for up to 8 Radios. Then just switch between them with the same popup.


> And, what if I wanted both connected at the same time.  Could I use TWO instances of MacLoggerDX: one hooked to my Pro III and the other hooked to my K3?


No even if you could run 2 instances they would both share the same set of Prefs and get confused.


> And, what type of access control and locking occurs with the logging database.  Is the database opened (via SQLite) only at the time that a record is to be read or written or is it held open during the time that MacLoggerDX is running.  Obviously it would be nice to access the same database file simultaneously from two different applications.


The MacLoggerDX SQLite database is designed as a single client system and only implements locking amongst it's own threads.

You could open the same database from two different machines but the results may be unpredictable if they both try to write to the same record at the same time.
