Grace, The easiest free way is to ask via the KDB website. If what you want to do is outside the current rules they will tell you. To change the rules you need money time and a strong stomach. Part 1 of the Rules section C has the Rule making Procedures, starts with a Petition for Rulemaking L

I've been told back when I did TCB work, if a spectrum holder/owner complains, they get attention, or if there are public complains, the FCC will look into it. If it can be demonstrated that there is a problem not already addressed by the regulations, they will consider it. To add an exempted d

In all the years of using household appliances, only the old vacuum cleaner motors had any noticeable effect - the TV over the air would get lots of "snow" scattered white noise on the signal. The water heater, and I have had tanks and instant on types, have relays that click seldom when not in

Mike, I agree and also that the digital device is not the main function/purpose of the appliance. Items like a digital clock in a microwave is not what you would worry about. Similar to why equipment that has dial or display lighting does not fall under the lighting standard EN 55015. Bob Heller
