Solar Radio Telescope
I assembled the JOVE receiver, at 20.1 mhz, and the GYRATOR II receiver, at 24 khz. The two receivers outputs were applied to a DATAQ adc. Using the WinDaq 194 software supplied with the adc, the two signals can be compared.
PARTS
1 JOVE 20.1 receiver JOVE
1 GYRATOR 24 KHZ RECEIVER AAVSO
1 WHIP ANTENNA PART NO. 21-903 RADIO SHACK
1 LOOP ANTENNA RADIO SHACK
1 MINI AMPLIFIER PART NO. 277-1008 RADIO SHACK
JOVE RECEIVER
All the components were mounted on a 24" by 10" white shelving board. Hook everything up per the above drawing, using 1/8" mono plug cables, except for the antenna inputs.
The JOVE receiver was assembled and calibrated per the supplied instructions. The only difference was a Radio Shack plug in power supply instead of a battery, Radio Shack PART NO. 273-1775. Get the M adapter plug with the power supply, make sure the plug is installed with the tip positive.
The only difference was a Radio Shack plug in power supply was added, Radio Shack PART NO. 273-1767. Get the F adapter plug with the power supply, make sure the plug is installed with the tip positive.
A 1/4" hole was drilled 5/8" down and 3/8" from the left, on the top left corner of the PC board, for an audio connector for the power supply, like the ones already used on the board.
The whip antenna for the JOVE receiver is a Radio Shack 102" steel antenna, PART NO. 21-903 . A 50' lead in cable, Radio Shack PART NO. 278-971 was used.
Cut one of the Pl-259 plugs off and replace with an F connector, Radio Shack PART NO. 278-277, so that it can be connected to the JOVE receiver. The antenna was mounted on an inverted plastic flower pot.
The amplifier is a mini amplifier from Radio Shack.
RECTIFIER-INTEGRATOR
The rectifier-integrator was assembled in a Radio Shack enclosure, part no. 270-1803, with audio connector input and output jacks. 1N914 diodes can be used, if you can not find the 1N60 diodes.
