DxSpot - DxSpot is your mobile access into the Amateur Radio DX cluster network. With DxSpot you can connect to the DX cluster of your choice. The internal database supplies the connection parameters to over 300 DX clusters. Once connected enjoy formatted table views of DX spots, DXCC information, connected users, cluster announcements, colorized WWV propagation data, and keep current with the latest DX news.

OZ2M - Next generation beacon - Next Generation Beacon hardware platform encompasses both analog and digital modes, i.e. CW FSK and MGM in a mixed mode configuration. The advantage of the mixed mode is that humans can decode the CW FSK by ear and the MGM can be decoded by computers way below what is audible. Therefore the MGM can be used for “pre-human-conditions” or early warning monitoring.
