Headline Details: A 1.5u Pocketqube. UNNE-1 will offer licensed radio-amateur around the world the opportunity to relay FM voice and AX.25 / APRS 300 / 1200 bps communications. The satellite will also transmit telemetry with its status and voice and CW messages. This all will be achieved by implementing a SDR based FM and FSK repeater. The FM / FSK repeater will be available all time and opened by squelch level without the need of a subtone. A small guess-game is being implemented by students of Universidad de Nebrija (Spain). The satellite will send a clue each week in its telemetry so radio-amateurs will have to solve the mystery by having all the clues.Game will be detailed in AMSAT-EA and Universidad de Nebrija webs, being all its data public and open. Launch is expected for 2024 in RFA mission, managed by DLR and ESA. Launch site: UK This satellite is part of Erminaz mission, a join effort by AMSAT-DL, AMSAT-EA and LibreSpace Foundation. The main mission for the satellite is acting as a FM voice repeater although due to its SDR nature it can repeat data too. This satellite is based on the hardware of HADES-D (SO-121) that’s currently being used to amateurs worldwide. FM satellites are very demanded and appreciated by the HAM community because they are easy to use, they don’t require of expensive transceivers and allow continental and even transatlantic contacts in some conditions. This is a satellite for the use of radio amateurs and with it we put into use HAM radio bands securing its use for the future. The guess game implemented by the University is a small challenge for the radio-amateurs and its mission is to make the reception of signals from the satellite fun for the young ones, expecting them to be future radio amateurs. Proposing a UHF downlink for FM voice, FSK data up to 1200 bps, APRS up to 1200 bps and FSK telemetry and experimental data up to 1600 bps and CW. Also a VHF uplink for the transponder. Planning a DLR/ESA launch from the UK in July 2024 into 500/600 km polar orbit - all TBC. More info from https://www.amsat-ea.org/ **A downlink on 436.888 MHz has been coordinated**
