(9) Set MODE switch to CW, FREQUENCY switches to 002.000 MHz, and
FREQUENCY VENIER control to +3 kHz. After 1 minute, record frequency counter
indication.
(10) Set FREQUENCY VERNIER control to 0 kHz. After 1 minute, record
frequency counter indication. Subtract from indication recorded in (9) above. Difference
will be between 2500 and 3500 Hz.
