The UHF transceiver meets the highest standards. The device is the first space-tested communications module to support the D*Star format, and can operate as a voice repeater and for the transmission of data packets. Special software allows on-board Doppler correction, which means the module can also be used for the inter-satellite link. The module is in use on the SPUTNIX and BST satellites, and has also already been supplied to many other customers. If required two modules can be accommodated on a PC104 form factor.
