CHANNEL 10
<Figures 4.18 and 4.19)
The circuit operation for this function is iden-
tical to that described for CHANNEL
4, except
that the Channel 10 mixing oscillator is com-
bined with the 44 MHz sweep. This develops
an r-f sweep frequency for Channel IO and
is applied to the receiver antenna terminals.
The frequency relationships between the
Channel 10 markers and i-f markers are
shown in Figure 3.3. Chroma alignment can
be performed as in the Channel
4 position by
use of the CHROMA switch.
