How is 2.4GHz safer John? So far there has been 2 product recalls on 2.4GHz sets. Safety should not have any reliance on the radio gear, there should be other systems in place that prevent injury. There appears to be a culture growing that is becoming dependant on the advantages of 2.4GHz which is not a certified fail safe system. As far as I am concerned, 2.4GHz has just two advantages and good ones at that: no crystal changes and little aerial needed. There are no safety features that I am aware of on 2.4GHz that cannot be equally achieved on 40MHz unless someone can explain to me what I am missing. The issue now is that 2.4GHz users may not be suppressing the electrical noise and causing interference to 40MHz users which is not permitted under the FRA build rules.
