Anyone advice me for ios app that can scan wifi channels, interferences, magnetic or other radio interference sources?

Sergio- Realize that the receivers in the PH 3 rely on their coding sequence to isolate them from being swamped by other signals. Said another way, the receivers have no components which filter out potential overwhelming nearby signals. They have as much ability to lock onto the transmitter signal as a router or cell phone does. In normal conditions, they can operate around other similarly powered 2.4 and 5.8 ghz spread-spectrum radios (WiFi, bluetooth etc). What they cannot filter out is strong analog signals. The Ph 3's radios (LightBridge Video, control link and GPS) will be blinded
(Swamped by huge signals into shutting down) from sources like FM, AM or TV broadcast towers, ham radio equipment (potentially) and high-voltage transmission lines. Since the EM fields from these sources decay with the square of the distance (twice as far from them you get 1/4th the level signal), when you are close to them, the signal can be huge. 200 ft away, it is much lower. Stay away from these sources. As well, your control and video signals decay the same...and at 2.4ghz and 5.8ghz, the "path loss" is significant. (the signal gets eaten up by water in the air really fast) 5.8ghz has 4X the "path loss" of 2.4ghz. Thus, when your PH 3 is far away, it is more susceptible to being over-run by interfering signals. Extra care! Don't worry about routers and WiFi interference. There is no real broadband RF sensor on any phone which would give correct readings for this purpose. Use "Prudent avoidance" as described above!
