The analyzer has become my best travel companion. It’s very discrete: everyone think you are playing with a mobile phone!. You can see in a moment what are the used frecuencies / channels at your location. One of the most interesting things if to carry it in the pocket in exposure mode and walk sometime in your neighborhood. In this way you can find easily what are the free frecuencies or channels. With the time, I learned how to distinguish between different devices:
WI-FI signals: In exposure mode they have a nice rounded shape about 20-22 MHz wide at most.
Wireless FM cameras (and ATV signals): You can see clearly the carrier and the modulation. If the video signal have sound, you can see a pair of sidebands about 6 or 7 MHz from the main carrier.
Bluetooth devices: This devices are difficult to detect, except in exposure mode. They appear as random peaks all over the spectrum up to 2483 MHz.
Microwave owens: Just full scale noise. I noticed the center frecuency drifts with the owen load: If nothing is inside the owen, the center drift up several MHz. Usually they are centered around 2450 having a noise bandwidth of about 60 or more MHz. Of course, they are the main signals at breakfast, lunch and dinner time.
