Hey Huub, didn't you know that the internet is the gospel of truth in our society? All those fact checkers and researchers objectively reviewing information, all the time in order to delivery 100% truth to the masses. I am sure there are companies who find plants in the rain forest that kill cancer and other miracles of nature. I am sure that those probably exist. Yes, there are companies who have diabolical natures in order to wipe out competitors (Microsoft anyone). But this is not evidence of a scheme from above to make us suffer. What is the point? Why would the Biledberger, Skulls, or whatever other frat boy group you choose have to gain by all of this? Nothing. Why have all the money in world? There becomes nothing left to buy. Why have all the power? There is nothing left to control. Conspiracy Theories always jump right to the top of the pyramid. But who controls those who control. It's a never ending cycle. In space I would just use a 57 through an 1176 and call it a day. |

There were tape recorders in the command module, they could be played back on a private communication channel. It was a 1" 14-track recorder that could record PCM/telemetry data as well as audio. Recording speeds were 3.75, 15, and 120 ips. However the microphones were dealt with, voice-band (300 Hz to 2300 Hz) audio was frequency modulated on a 30 kHz subcarrier, which was then modulated onto the audio/biomedical subcarrier of 1.25 MHz. PCM telemetry data was phase-shift encoded on a 1.024 MHz subcarrier which was also phase modulated onto the same S-band frequency. This data could be selected as 51.2 kbps (high rate), or a whopping 1.6 kbps (low rate). Also, backup audio data could be sent on this channel as well. The combination of PCM telemetry data (on a 1.024 MHz subcarrier) and audio/biomedical data (1.25 MHz) was then modulated onto the S-band carrier of somewhere between 2106.4 and 2287.5 MHz, depending on the direction of communication and from/to which spacecraft. Once on the ground, voice and data were transferred via standard leased phone circuits. Data would be transferred at somewhere around 2400 baud, from what I remember, to the spaceflight centre for display. Depending on what the flight controllers had selected on their screens, the remote stations would filter out different things to keep the data rate reasonable. They had more data coming from the spacecraft than they could get back to Houston. -Dale |
