GETTING STARTED, cont'd.

The synchronous detector will lock to the strongest signal that is within the IF passband when it is activated. Most of the time, the strongest signal will be the carrier of the desired signal. First, be sure the main tuning is set to within 1 kHz of the desired station's transmitting frequency. Press the 'AM SYNC' button to activate synchronous operation. If adjacent channel interference or any other undesired signal is sufficiently strong, the synchronous detector may lock to it instead. In that case, press the 'AM SYNC' button again to turn the synchronous detector off, and repeat the tuning process. For severe cases of fading, set the audio bandwidth to 4 kHz. If interference is present, press the SSB USBLSB button to select the sideband with the least interference once 'AM SYNC' has been selected. If the interference is sufficiently severe to prevent reception, select a narrower IF bandwidth and retune to the desired signal. After reception is obtained, select a wider bandwidth and/or alternate sideband if desired. When 'AM SYNC' has been activated, moving the TUNING knob will cause the SYNC circuit to momentarily disengage (indicated by 'SYNC' flashing), then back on again when tuning has stopped. AM SYNC does not function on the AIR band, and will not operate properly on intermittent transmissions such as those encountered on CB radio, and AIR bands. For those types of transmissions, use the AM mode. Press the AM SYNC button to turn the synchronous detector off before selecting LSB or USB modes.

SSB OPERATION

Tuning in a single sideband (SSB) signal can be somewhat frustrating for the first time listener. In either of the SATELLIT 800 MILLENNIUM's SSB modes, LSB (lower sideband), or USB (upper sideband), the receiver will select the 2.3 kHz bandwidth automatically (the receiver may be programmed to NOT automatically select a bandwidth. Refer to 'Automatic Bandwidth Setting With Mode Selection DISABLE (ENABLE)' in,the 'Special Use Features and Functions' section of this manual). Generally, LSB is used below 10 MHz and USB is used above 10 MHz. When initially tuning in the desired station, tune slowly. If the station is unintelligible, try the other sideband, again tuning slowly. A station tuned in on the wrong sideband is totally unreadable but a station mistuned on the correct sideband may sound like 'Donald Duck'. Further tuning will result in a more normal voice pitch.

FM OPERATION

FM reception is perhaps the easiest mode to use on the SATELLIT 800 MILLENNIUM. The AGC and BANDWIDTH settings are not used in FM. In fact, attempting to activate these buttons will result in an 'ERROR' beep. All FM stations in the U.S. end in an odd 100 kHz, i.e. 97.7 MHz, and are spaced 200 kHz apart. The SATELLIT 800 MILLENNIUM has the ability to tune in 20 kHz steps to allow tuning in between stations to help eliminate interference to weaker stations that could be covered up by stronger adjacent stations. Additionally, when headphones or external speakers are used, true stereo reception is possible. The front panel stereo

indicator will light when a stereo station is tuned in. The receiver will automatically switch to stereo and provide left and right audio from the headphone jack, line output jacks, or external speaker jack. If the headphones or external speakers are removed while listening to a stereo broadcast, the receiver will provide monaural audio from the internal speaker, and the front panel stereo indicator will disappear.

AGC OPERATION

The SATELLIT 800 MILLENNIUM provides the ability to select a Slow or Fast AGC setting. Either of the two settings will permit automatic control of the receiver's gain thereby producing a constant audio output free of distortion. Generally, the Slow AGC setting is preferred for reception of AM and SSB signals. The Fast AGC setting allows more rapid automatic receiver gain adjustment to quickly fading signal levels. The AGC does not function in the FM mode.
