RadioDXCluster for Mac

From Steve Muncy:

RadioDXCluster is simple, configurable terminal software used to control your TNC (Terminal Node Controller) to connect with your local AR-DX Cluster using your radio. This program combines features contained in MacTNC, a TNC control program, and NetDXCluster (formerly MacDXCluster), similar software that accesses DX Clusters via the Internet rather than a radio link.

RadioDXCluster offers user-definable buttons and standard TNC command buttons. This software requires Mac OS X 10.1.3 or later, and a TNC and radio for connection to a DX Cluster.
