[TVI-RFI-EMI] Part15 device frequencies

Just read the e-mail about Part 15 devices frequencies being at 303, 
308, 310 and 315 MHz!!! Whose idea was it to allow these devices in a 
military band in the first place??!! I have read stories about Air 
Force radar being responsible for opening people garage doors. I 
thought at first the door receivers were not very selective, but 
after seeing the list of UHF frequencies,I had to shake my head. Hope 
the manufacturers are learning their lesson and getting out of that 
part of the spectrum. :-D

                                                                 Dan
