I certainly agree with you, Nemesis....I would not want to cause anyone to crash. I don't doubt what you are saying, but I need to understand this. [sm=drowning.gif] If an airplane is flying on one of the 72 frequencies and WWM's transmitter/receiver is operating on a 75 frequency (due to changed crystals, only), why would it interfere with the plane? [sm=frown.gif] The different frequencies are at least as different as two channels of the same frequency (for example: 75.810 and 75.910 can be used together).

There must be some reason, if a person can have their radio equipment converted, but I just don't know enough to understand it.

Thanks!
