Project Summary
1. Construct a Receiver sensitive to 20MHz radiation
2. Construct an telescope to receive 20MHz radiation
3. Observe the Sun and its activity using the telescope

The Receiver
• Series of amplifiers and tuners that can be plugged into the sound card of a computer
• Tuned to 20 MHz using capacitors

The Antenna
• Two diploes connected together
• Dipole is ½ the wavelength of the 20MHz wave
• Signals brought to the telescope using co-axial cables
• Sensitive to radiation perpendicular to the cable

20MHz Radio Telescope
• Dual-dipole
• Signal combiner adds the signals together
• Delay line makes the distance both waves travel the same
• Antennae are made from copper wire and insulators.

Software
• Skypipe– Produces a plot of radio flux vs. time– Data can be shared with others
• Produces on-line database that can be mined

Construction
• All components for basic receiver come with the kit
• Requires soldering the components to the board, learning to recognize different electronics
