When tuning signals where the stations are very close together, the main tuning dial can be left at a

slightly higher frequency and the fine tuning can be done with the BANDSPREAD control.

SHORT WAVE TUNING

Short wave Broadcast Stations:

Set the controls for AM Broadvast.

Select the short wave band desired with the BAND switch.

On the short wave bands, all stations are close together, therefore the main dial is used for coarse

tuning, to a point slightly higher than the frequency desired. Then use the BANDSPREAD control for

fine tuning. Always return the BANDSPREAD control to CAL when using the main tuning dial.

When there is noise on the signal, shift the OFF-ANL switch to ANL. Many kinds of noise will be

reduced considerably when the Automatic Noise Limiter is used.

CW TUNING

To tune to a CW signal use the following procedure:

1. With the AM-CW switch in AM position, tune the main tuning control until a steady signal is

found.

2. Turn the RF GAIN control to the lowest possible point while still retaining an audible signal.

The VOLUME control should be at midpoint of its range.

3. Tune in the signal with the BANDSPREAD control.

4. Put the AM-CW switch in CW position and adjust the BFO TUNING for zero beat.

5. Retune the signal with either the main tuning control or the BANDSPREAD control, and adjust

the RF GAIN control for the volume you want.

6. When you want to tune in another CW signal use the main or BANDSPREAD tuning and RF

GAIN controls.

SINGLE SIDEBAND TUNING

Use the procedure given above.

Tune the BANDSPREAD dial very slowly until the voice being received sounds most natural.

Keep the RF GAIN control as low as possible.

FM TUNING

Use the procedure given for AM tuning.
