Modification for SuperStar 2200

To get 10-meter, cut trace from + 5 Volt to Pin 8 and 9.
To get 12-meter, cut trace from GND to Pin 7 and connect Pin 7 to + 5 Volt.
Make a new VCO Block.
Re-tune both Transmitter and Receiver-part.

VCO operates between 17.115MHz (Ch.1 Band A) and 18.445MHz (Ch.40 Band E),
output on Pin 6 is 36.780MHz (Ch.1 Band A) to 39.000MHz (Ch.40 Band E),
and output on Pin 9 is 2.550MHz to 2.110MHz inn all band.
The VCO-voltage (TP1) operates between 4,5 Volt (Ch.1 Band A) and 0,5 Volt (Ch.40 Band E).
