Spacemanic's Murgas - the UHF/VHF Transceiver is a space-grade, software-configurable UHF/VHF transceiver for long-range satellite communication.

The robust device is enables transmitting and receiving of signals at the same time without interference.

It has a half-duplex, narrow-band operation and RF parameters that are fully configurable in orbit.

Two modules for full duplex are also provided and HAM services (beacon, CW, digipeater) are included.

Key features

  • Programmable RF carrier frequency and FSK deviation
  • Supports KISS, CSP, and AX25
  • Integrated heat sink (also works as EMI shield)
  • Full and half duplex operations
  • Two modules for full redundancy
  • Compatible with components from other vendors
  • GFSK/GMSK, CW modulation
  • Compatible with Spacemanic cubesat standard
  • Engineering model and simulator available
