The CUAVA-1 satellite was deployed into space on 6 October 2021. This paper summarises attempts to detect CUAVA-1’s radio beacons and other radio signatures. We attempted to detect CUAVA-1’s radio beacons near 437 MHz using ground stations at the universities of Sydney and New South Wales, at Saber Astronautics, and via the global amateur SatNOGS network. While some signals with the correct centre frequency, periodicity, and Doppler signatures were detected during one pass, they could not be decoded. Some other passes showed an occasional signal at the correct Doppler-shifted frequency. In contrast, beacons from other satellites (e.g., TauSat-1) were detected routinely. Direct transmission of commands on the uplink frequency also led to no observable results. Accordingly, the putative CUAVA-1 beacon signals are currently considered to be noise. We also observed CUAVA-1 using the University of Tasmania’s radio dishes in the frequency range 2.2 to 2.3 GHz, hoping for signals at harmonics of microprocessor clock or communication system frequencies. During one pass signals with the correct Doppler signature were observed at a center frequency of 2221.50 MHz, close to but 36 MHz away from the 5th harmonic of the downlink frequency. These signals have not been observed again and are currently interpreted in terms of either interference or another satellite. In summary, neither beacons or other radio signals are considered to have been detected from CUAVA-1 to date and the satellite is considered lost.
