| Headline Details: A 1.5 P Pocketqube. UNNE-1B uses the same satellite hardware and software as the original UNNE-1, but will be launched with SpaceX instead of RFA due to delays in the latter launch. As with UNNE-1, it will offer licensed radio amateurs worldwide the opportunity to relay FM voice and FSK-derived digital modes. The satellite will also transmit telemetry data reporting its status, a CW beacon, and a CODEC2 digital voice message. All of this will be achieved through the implementation of an SDR-based FM and FSK repeater. The FM/FSK repeater will always be available and will be activated by squelch level, without the need for a subtone. As an educational payload, a small guessing game is being implemented by students from Universidad de Nebrija (Spain). The satellite will send one clue per week within its telemetry, and radio amateurs will need to solve the mystery by collecting all the clues. Details of the game will be published on the AMSAT-EA and Universidad de Nebrija websites, with all data being public and open. With this mission, we will replace the SO-124 and SO-125 FM repeaters, as both satellites are expected to decay at the beginning of 2026, and HADES-SA, also scheduled for 2026, supports only digital transmissions. FM voice repeating is a highly demanded service within the community, as it enables long-range communications using simple setups. The CW beacon and the recorded CODEC2 transmission also represent a small challenge for those wishing to receive them, specially the CODEC2 signal, which requires the use of a computer and dedicated software. This may be particularly appealing to radio amateurs who enjoy exploring the digital side of radio communications. With this mission, we are also activating the VHF and UHF amateur satellite service bands for use by the amateur space community. Proposing a V/U FM transponder and FSK 50-1200 bps with Telemetry up to 1600 bps customizable by command. Also CW. Launch is expected in June 2026 on the SpaceX Transporter-17 mission. The launch broker is UARX. More info at https://www.amsat-ea.org/proyectos | ||||
