FPVFreq solves the problem of finding VTX frequencies that do not interfere with each other. Ever been half way down the field inverted in the middle of your best hang time of the day and have someone fire up their VTX and it stomps all over your video? FPVFreq makes it easy to find clear channels to use without having to waste your flying time experimenting by manually changing VTX channels. The app calculates safe distances between channels and warns you when two or more channels might interfere with each other or generate IMD (intermodulation distortion) which can cause ghosting to appear in your goggles or display device. If several pilots are flying and another pilot shows up you can use the Find feature to easily select new channels that wont have interference on them or worse wont cause interference. FPVFreq has several presets you can use made of well known frequencies that will not interfere with each other and the app covers all of the current FPV bands. Simple to use and works with the iPhone and iPad.
