Supposedly certain channels (especially channel 14) are close to this frequency, and this SOS frequency is known for many false positives, which is why they are phasing it out and going to one in the 400mhz range, but the equipment will be much more expensive (I was told from around 50 bucks for current transmitters to thousands of dollars for the new ones). Can you imagine spending some time with your wife in the bedroom and all of a sudden you have the village people walking in lol.
