SHORTWAVE 'METER' BAND DESIGNATOR ENTRY To facilitate tuning to particular sections of the shortwave band that contain many worldwide broadcasts of news, information and music, the SATELLIT 800 MILLENNIUM permits entry of the 'METER' band designator. In some cases, the worldwide broadcast station may not announce its exact operating frequency, but will announce the 'METER' band in which it is operating or to which band it will move to improve worldwide reception at a particular time of day. By entering this 'METER' band number, the receiver automatically tunes to the low frequency end of the corresponding 'METER' band. The search for the new station location is thus limited to a particular smaller section of the entire shortwave band spectrum. The Shortwave Band Designators and corresponding frequency ranges are as follows:

FREQUENCY RESOLUTION

The SATELLIT 800 MILLENNIUM tunes in the following steps:

Shortwave Band Designators
Band	Low Freq	High Freq
120 Meter	2300 kHz	2500 kHz
90 Meter	3200 kHz	3400 kHz
75 Meter	3900 kHz	4000 kHz
60 Meter	4750 kHz	5060 kHz
49 Meter	5950 kHz	6200 kHz
41 Meter	7100 kHz	7600 kHz
31 Meter	9500 kHz	9900 kHz
25 Meter	11,600 kHz	12,100 kHz
22 Meter	13,570 kHz	13,870 kHz
19 Meter	15,100 kHz	15,800 kHz
16 Meter	17,480 kHz	17,900 kHz
13 Meter	21,450 kHz	21,850 kHz
11 Meter	25,600 kHz	26,100 kHz

Press the 'BAND' button as required to enter the shortwave band tuning mode. At this point, you can enter a frequency with the 'Direct-Key-Input' buttons, or use the TUNING knob

and/or the and buttons to change frequency.

To enter a shortwave band 'METER' designator, press the 'SW BAND' button to display a flashing 'METER' number entry prompt. The prompt will flash for approximately 3 seconds after the SW BAND button is pressed. While it is still flashing, enter one of the listed two or three digit Band numbers corresponding to the desired 'METER' band designator using the 'Direct-Key-Input' buttons. While the 'METER'

annunciator is flashing, the and buttons can also be used to step quickly from band to band. After selection of

the 'METER' band, use the TUNING knob orand buttons to change the frequency, or press the 'Direct-Key- Input' keys to make a direct frequency entry.

FRONT PANEL LOCK (UNLOCK)

All keyboard entries, display settings, and entries from the tuning knob can be locked if desired. First, be sure the SATELLIT 800 MILLENNIUM is not in SCAN mode.

Press and hold the button which is one of the 'Direct- Key-Input' keys. The LOCK annunciator will light indicating the front panel controls are LOCKED out. POWER on/off will still function as well as VOLUME, BASS, TREBLE, and AIR BAND SQUELCH. Press and

hold the button to unlock. The LOCK annunciator will extinguish, indicating the front panel controls are once again active.

AM SYNCRONOUS OPERATION

For general tuning and listening, normal AM is best. If, however, the received signal sounds distorted, or interference from adjacent stations is present, AM synchronous should be engaged. The synchronous detector in your receiver can greatly reduce the severe audio distortion that can occur due to signal fading. The detector also permits selectable tuning to either the upper or lower sideband portion of an AM signal. Since most all AM (LW, MW and SW) broadcasting generally uses double-sideband transmission, detection of either of the two sidebands results in full reception of the transmitted information. The selectable sideband tuning and detection not only aids reception by permitting tuning to the stronger or less distorted sideband, but also permits rejection of the sideband nearer to the interfering signal(s).
