Welcome to RADIOSOFTWARE.ONLINE!

This website represents a selective, members-only club for land mobile radio (LMR) enthusiasts and professionals, and it is the largest and best-known community of its kind. One of the club's achievements over two decades of work is building a radio software collection and publishing metadata about it on the Internet. Membership in this club is a privilege, not an everyday entitlement.

The procedure for joining is not complicated, but it is not guaranteed for everyone:

  • 1) Carefully read the FAQ and About pages.
  • 2) Provide something from the Wanted list, or, if you do not have anything from there, consider becoming a paid member for $199/year.
  • 3) If you have done that and everything is clear, visit the Membership section.

If you do not understand something, disagree with our terms, are not comfortable with the price, or are looking for free access, simply pass by. We are not a good fit for each other.
