Note: Operators in the United States need to be aware of the following: Stations operating in an automatic mode, on certain portions of the HF bands, must restrict transmission bandwidth to 500Hz. See section 97.221(b) and(c) for frequencies where automatic stations are not bandwidth limited.

It's recommend for most to use the app bundle, the developer setup is a little involved. The app bundle will check for updates automatically and download delta files - only the needed changes - and install them after restarting the app.
