If pin 10 of the PLL is tied low, remove the ground and pull the pin high to go down 64 channels ! (as found in the Washington)
If the pin is tied high, remove the voltage and ground the pin to go up 64 channels !
The state of pin 10 depends on the country that you are in and how it has been modified for the frequencies that are used.
The loop crystal can also be changed to give you more bands of channels if needed, you can use a crystal switch to switch whatever crystals you use to give you the bands that you want.
Power Tweek and Modulation
1) Cut TR32 2) Change R99 to a 2.2k resister. 3) Change R94 to a 2.2k resister. 4) Re-tune L36 and L37 for maximum RF forward power.
