UHF oscillator
UHF oscillator.
Pin 12 uses both as band switch. Connecting
pin 12 to VCC via 22 k sets to UHF ;
connecting pin 12 to GND sets to VHF. To
use VHF SW voltage open rather than GND,
connect a resistor of around 10 k.
Changing capacitor of 6pF connected to pins
12 and 15 of test circuit 2 varies the
oscillation frequency range. Be careful not to
set the constant too large, because abnormal
oscillation may occur.
