Demodulators The F3 button in the Sweep or Analyze Mode can select the following demodulators FM WIDE 250 kHz as used with FM Broadcast and TV sound channel e FM NARROW 15 6 kHz as used with most two way communications e SubCFM uses 250 kHz primary IF and 15 or 6 kHz secondary demodulator AM WIDE 250 kHz used for fast scanning AM NARROW 15 6 kHz used with AM Broadcast short wave CB aircraft SSB CW 6 kHz used with short wave marine amateur radio Technical Notes e DEMODULATING NARROW DEVIATION FM WITH A WIDE 250 kHz FILTER The OSCOR will sufficiently demodulate narrow deviation FM signals when operating in the wide 250 kHz bandwidth The automatic gain control will continuously adjust the audio level to the correlator or headphones for optimum results e WIDE DEVIATION FM WITH A NARROW 15 6 kHz FILTER If a narrow bandwidth filter is used on wide deviation signals over modulation of the signal profile and distorted audio will result e USE OF THE PROPER DEMODULATOR WILL RESULT IN THE BEST RECOVERED AUDIO LOWEST DISTORTION AND LOWEST NOISE Surveillance devices using FM modulation will normally produce a small percentage of AM modulation due to poor oscillator buffer design unregulated power supplies or effects of antenna reflection AM modulated devices may also contain a small percentage of FM modulation primarily due to an unstable oscillator e Receivers also respond to FM signals with AM demodulatio

Three approaches are recommended to confirm threat existence 1 Listen to the received signal using the headphones 2 Change the environment turn up some music whistling works very well but may not be considered covert 3 Use the Correlate Confirm Mode as described below Correlate Confirm Mode The OSCOR has a built in ringer which sounds like a telephone ringing designed to maximize the correlation if an eavesdropping device is present REI OSC 5000 44 Section 2 Detecting Video Threats To use the correlator confirm ringer 1 With a signal selected in the Analyze Mode press the CORR button to enter the Correlate Mode 2 Press F4 labeled CONFIRM or the TONE button to activate a ringer tone output for positive ID The volume of the ringer tone can be adjusted as described below To set the volume of the confirm tone alert 1 With the confirm ringer ringing from the procedure above select the desired volume by pressing one of the following F1 LOW F2 MEDIUM F3 LOUD 2 To terminate the ringing press the TONE button or the F4 button labeled SILENCE The MENU button will exit the menu but will not terminate the ringer The LOUD setting for the Correlate Confirm Mode is much louder than a typical telephone and is normally used only in large conference rooms or for penetration into an adjacent room Note In some cases it is possible to have false readings from the loud mode because the ringer is so loud tha

164. y analysis function also provides the ability to inspect the LO image in the OSCOR The LO image is a false image that is generated internally by a Local Oscillator in the OSCOR This LO image only impacts the WhipHi and Discone antenna inputs and the basic result is that if a very strong signal exist in one input it is possible for this signal to also occur in the other input at a significantly reduced level For example a very strong signal exists at 98 5MHz it is possible for a false image to occur at 1598 5MHz in the Discone input This image is not of significant concern except that it can cause some confusion when analyzing signals in the Discone frequency band To access the Harmonic Frequency Analysis 1 Ensure that the OSCOR is in the Analyze mode and that the desired signal is selected 2 Press the MENU button labeled CONFIG 3 Press the F4 button labeled FREQ ANALYSIS REI OSC 5000 33 Section 2 Detecting Video Threats 4 Us the FI F4 keys to perform various frequency analyses Press to return to the original signal Press F2 to tune directly to the first sub harmonic of the original signal Press to tune to the next harmonic of the original signal Press F4 to view the LO image of the original signal if in the WhipHI the LO image original signal 1500MHz if in the Discone the LO image original signal 1500MHz Note the frequency analysis menu is linked to a particular frequency being a
