What signals will the DF work with – AM, FM, TV, SSB, Noise, CW, Pulse?

When the unit is used as recommended with a narrow band fm receiver, it will work with any signal that has a carrier that remains within the IF bandwidth of the receiver. This would include unmodulated carriers, narrow band fm modulated signals, and amplitude modulated signals. Television video carriers can also be used, but the system will not track broadband noise or single sideband signals. Commercial broadcast (wideband) fm signals require that the receiver bandwidth be increased to 150 KHz. Series 5900/6000/6100 provides a selectable sweep rate, and by setting it to 1200 or 2400 Hz, the deviation is increased to the point where a wide band fm signal may be tracked. Accuracy and sensitivity, however, will be lower. The latest firmware version provided with all of our direction finding systems allows signals as short as 80 milliseconds to be tracked.
