FM Radio Station Testing Part 7

The 9-volt powered mini radio station is set to broadcast on the FM band near 102 MHz with more tests using a tiny 1.75-inch circular loop antenna. Today's tests include a harmonic and range study, along with orientation reviews. A very sensitive Chinese multi band radio is at the receiving end. The photo does not show the actual test range distance. In this second day "on the air" test, a small script will be sent out over the "air waves." Stay tuned to this project and the radio station just keeps growing and growing.

FM RADIO STATION TRANSMITTER TESTING PART 7
The next phase of the radio station is testing and calibration of the transmitter and equipment, and running more experiments to pace the radio station and see what works best.

ROBOT EXPLORER LOG 10
MISSION CONTROL
So now you've created a new life form, sent it to a new world and it's exploring the surface. You'll need a mission control center to gather its images, data, findings, and discoveries.

The Big Brain machine initiative continues to expand. Recent projects include Robot Explorer, designed to explore strange and erie new worlds at the outer fringes of the Solar System. Establishing and maintaining contact with remote robotic autonomous intelligent beings requires a control center, i.e. Mission Control, for the gathering of images and various telemetry signals for analysis.

HISTORY
The previous construction of Mission Control was a command center to control massive space telescopes and included the earthen supercomputer to conduct and make their projects possible.

NEW MISSION CONTROL
The new Mission Control is designed with several purposes, though primarily for establishing contact with autonomous intelligent beings created by the laboratory which will explore new distant worlds. 

SETUP
The current setup is a desktop proof of concept using frequencies centered around 1.2 GHz on four channels, and additional channels in the UHF, VHF range for long range wireless operations.

EXPERIMENTS
Experiments conducted include the camera eye on a robot that feeds images into a micro-miniature 1.2 GHz transmitter. The camera eye and transmitter remain on board the robot and wireless send images to the base station on one channel. This channel includes video and audio bands.

CONVERSION
The base station at Mission Control has a 1.2 GHz receiver that converts the signal to standard NTSC composite 1V p-p (AV) and feeds it into the TV. The TV has audio/video AV input.

MORE CHANNELS
A second Parallax Propeller chip, known as the sensor chip, transmits data telemetry on the VHF band USA channel 3. This is received directly by Mission Control's multi-band analog TV. Data transmitted includes information from sensors and various parameters including the condition of the robot and its decisions.

RECORDING TELEMETRY
The  TV monitor also has video out which can feed into a VCR or other digital recording device for a record of the mission's proceedings.
