The AJH Synth Lunar Module (Black) simulates the Radio Transmissions from the time of the Apollo Space Flight between "Mission Control Houston" and the Shuttle in Space. The famous Radio Transmissions of that time have often been used in tunes or incorporated into DJ Sets; now you can create your own space communication. To be "Mission Control Houston", the Quindar PTT Button (Push to Talk) adds a short 2.525Hz Quindar Tone at the beginning of the Transmission, then at the end of the message, the PTT Button is released and a short 2.475Hz Quindar Tone is added to the Audio. In this Mode the Frequency Band is slightly reduced. For "Astronaut Comms" press the Capsule PTT Switch, which adds coloured Noise, Distortion, Bandwidth Reduction and either Hum or LGM Noise to the Audio Signal. The AJH Synth Lunar Module can also be used as a stand-alone Noise Source Simulator.
