The majority of software on this site is provided free of charge.

You are of course free to download and use most of the notes and code on this website without charge, however there are unfortunately not enough hours in the day to offer free support. If you would like to pay for commercial support for your station or business, please contact Broadcast Ltd.

If you don't need support but any items on this site have been of use, why not consider making a donation. Donations help cover the cost of this site to keep it online and allows us to spend more time working on free and open source projects like the ones documented here.

Donating does not mean we can offer support or spend time to adding a specific feature or resolving an particular issue, but it does help facilitate improvements in general.
