SPECIALTUNING TECHNIQUES AND CONTROLS In addition to the standard tuning operAations described previously , use the following controls for special operations. AMNARROW/WIDE SELECTIVITY SWITCH RF G A I N CONTROL Some stations transmit their signal so that very little space exists between their airspace and the station next to them on the band.
HEADPHONE USE LOCK SWITCH USE While not a control, you may consider using HEADPHONES to obtain the best audio clarity when listening to SW. Since many SW stations broadcast only marginal signals, using HEADPHONES will enable you to distinguish between the signal and the noise usually encountered at night.
EXTERNA R SWITCH Located in battery compartment of the unit, is a switch marked, 9K/10K. This switch selects the incremental frequency STEPS for the M W b a n d , depending upon your geographic location. In the USA, 10K STEPS are used, so the switch should be set to its 10K Position. In other parts of the world where they use 9K STEPS, move the switct to the 9K Position.

SPECIAL SSB/CW RECEPTION TECHNIQUES Many stations transmit unmodulated telegraph transmissions in the shortwave b a n d . To r e c e i v e t h e s e s p e c i a l M o r s e c o d e characters, the radio uses a special circuit a beat-frequency oscillator, to modify the transmitted signal so that you can hear it. this particular type of telegraph transmission is called continuous wave(CW) transmission . Many stations transmit voice signals with a suppressed carrier in the single side band .
