UK Radio Amateurs Annual CW Table - The purpose of the table is to encourage CW activity on the HF bands and six metres. Each year participants start afresh and work as many DXCC entities on each of the ten bands as possible between 0000Z on 1st January and 2400Z on 31st December

RadioDXCluster - MacOSX 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.

MacTNC - MacTNC is simple, configurable terminal software used by amateur (ham) radio operators to control a TNC (terminal node controller). MacTNC performs most of the same functions of other terminal software, but includes buttons for standard commands, and allows the user to configure additional buttons for special purposes. MacTNC works only user Mac OS X because it relies on Unix components of the current operating system.
