HADES-ICM is a 1.5P PocketQube satellite, measuring 5 cm × 5 cm × 8 cm, and weighing 400 g. It carries a hardware payload to test a low-power active graphene radiator developed by SmartIR, a spin-out from the University of Manchester, aiming to assess its feasibility in space. It is equipped with an SDR-based FM and FSK repeater for AX.25/APRS communications at 300/1200 bps, operating in the UHF band for downlink and VHF band for uplink. Also, as a challenge made with icMercury, telemetry will send FSK English formatted text messages, part of a history, to be collected.
The main mission is to act as a FM voice repeater. The FM / FSK repeater will be available at all times and opened by squelch level without the need of a subtone. As an improvement from previous missions, maximum power is now 0.25W when battery is charged (the amplifier uses battery energy), allowing easier QSOs with handheld antennas like Arrow or Elk and less sensitive receivers.
