VHF/UHF Receiver

The picture below show a VHF/UHF receiver assembly based on the Universal Software Radio Peripheral and a standard TV-tuner. The board on the left is the S-band transceiver module described earlier.

VHF/UHF receiver

The TV-tuner based VHF/UHF receiver can receive a 6MHz wide RF spectrum anywhere in the range 50-800MHz. It has a noise figure around 8dB, which is not good enough for Lunar comms; however, it is a good cheap starting point for breadboarding and experimentation. Using a modest yagi antenna and a low noise preamplifier, we have been able to receive signals from low Earth orbiting satellites.
