AJH Lunar Module Black
This module is designed to re-create the ground to space and space to ground transissions from the Apollo era.
To be "Mission Control Houston" the Quindar PTT (push to talk) button adds a short 2,525Hz Quindar tone to the start of the transission, then at the end of the message the PTT button or switch is released and a short 2,475Hz Quindar tone is added to the audio. The bandwidth is slightly reduced in this mode.
For "Astronaut comms" we press the Capsule PTT switch, which allows us to add coloured noise, distortion, bandwidth reduction and either hum or LGM (Little green men space tone) noise to the audio signal.
Obviously the Lunar Module can also be used to add noise, hum, distortion, bandwidth reduction and LGM noise tone to any modular level audio too, and if the mic is left attached theremin like sounds can be added too with careful loudspeaker feedback.
Power consumption: 35mA at +12 V and 10mA at -12 V
Depth: 26mmHP : 14
