About
The TRX-U is a software-defined UHF/VHF transceiver from AAC SpaceQuest designed for CubeSat command and telemetry links. It provides full-duplex operation with separate UHF and VHF bands and supports standard amateur satellite protocols as well as custom modulation schemes. The SDR architecture allows flexible configuration of modulation, frequency, and data rate. Compatible with SpaceQuest ANT-100 antennas and standard CubeSat ground stations.
