Not knowing the specifics, your location, freqs attempted, etc... I'll hazard a quick answer. Not knowing where you are relative to the tower(s) you are trying to monitor, I can't actually say why you aren't hearing KSP well... The best thing to do is load ALL KSP freqs into your scanner; that done, if you want to cut down on the number of objects scanned, then keep the two or three with the best signal. Personally, I have most of the freqs for the three posts I monitor loaded because sometimes they just don't work as advertised.... regarding the iFone's reception versus your scanner: the person providing the feed obviously has chosen the freq or freqs that come in best for the location of the scanner providing the feed... You can't compare an iFone app to a scanner because they are two different radios with different sources of signal.
