Selects the 1st Local Oscillator frequency�
Depending on a combination of the two operating
frequencies in the Dualwatch mode, the transceiver
might generate a spurious signal on a specific receive
frequency� This may cause the S-meter to fluctuate,
even when no signal is received, for example�
If this occurs, the Heterodyne function may help� The
Heterodyne function shifts the 1st Local Oscillator
frequency to the opposite side of the signal to change
the frequency combination�
