frequencies. The PLL input & VCO output connections on
the board connect to the Synthesizer. The Mute output is
used to tell the microprocessor when a signal is received to
stop the PLL scanning the channels.
There is currently
no plans to produce a PLL Synthesizer Kit to suit this
receiver.
4.
An external 10.7MHz FM demodulator connection is
provided on the board. This can be used for an optional
external wideband 280kHz IF, for Japans geostationary
GMS5 Satellite. The audio from the external demodulator
can be fed back into the input of the TL072 as show on the
circuit diagram. The 10kohm resistor on pin17 of the
MC13135P would need to be lifted on the 1uF capacitor
side & a switch fitted for switching between the two
demodulators.
The MC13135P seems very sensitive to static so if you
want to experiment with the Kit, make sure that the
power is turned off before soldering anything on the
board.
