To counteract an excessive decline in the tuning transconductance in the event
of the oscillator circuit capacity being enlarged, tuning diode, V23, is connected
to tuning diode, V22, by connecting C95 and C76. This is effected with data, D8,
on HIGH via level shifter, A13N2-A, and FET switch, V21.
The VCO drives 2 base stages. The signal is supplied to loop 3 via V26, and an
ECL level is generated in V34, which drives the loop divider.
