3.6 LO Spare Crystal Socket
There are 4 spare crystal sockets besides the 7 installed crystals in the LO module. When
the MHz Indicator shows 146, No. 8 socket is for ^A" on the 100 KHz Selector and No. 9
is for "B". When the Indicator shows 147, No.10 socket is for "A" on the 100 KHz
Selector and No. 11 socket is for "В" on the selector. Each crystal adds 10 channels
with 30 KHz separation.
The frequencies are calculated as follows:
Desired Operating Freq. — CO, Етед. — 10.7 (MHz)
f (MHz) = <A ———
9
For exampl, if you desire to operate on 146.02 MHz
146.02 (MHz) — 11.265 (MHz) — 10.7 (MHz)
f (MHz) = _13.784 (MHz)
