om... (Dave Platt) wrote in message ... My HT, power supply and amp are in the living room. The coax runs into the kitchen with a Diamond 2 meter magmount antenna out the kitchen window on a steel plate. I have had no problems for 11 years. Yesterday I keyed down and heard a buzz coming from the kitchen. I had a friend key down, went to the kitchen to see where the buzz is coming from and it's coming from the outlet next to the window that has NOTHING plugged into it! My units are all plugged in in the living room. What's happening here RF wise? If you have any idea, please either post it here or email me. I have an Extra Class License but this isn't in the books :-( Thanks in advance! Is that by any chance an outlet with a GFCI (ground fault circuit interrupter) built in? Current electrical codes generally require that these be used for all outlets around areas with water. They usually have a solenoid or other sort of circuit breaker inside, and it's possible that this is being partially activated by rectified RF currents. Duh! - pull it off the wall and have a look is a good place to start. Andrew VK3BFA Not always - are those things "visible". I agree with the gentleman's thought of a GFIC being tripped or influenced somehow with RF. RF does strange things and if you're not an old hand at it, it can be very confusing - even with experience, it can create some confusion! Move the antenna to another spot in the room or house away from outlets, etc. While you may not hit the same repeaters, you can at least eliminate the RF as the problem of the buzzing at that outlet. On the other hand, it is possible too, that if the GFIC wasn't bad to start with, an RF Overload "could" have created a problem - depending on the make up on that particular unit. They're not that expensive to replace, if you know how to do one. While I don't think it a high probability of the RF doing damage to it, I wouldn't dismiss the thought completely. I've seen and I'm sure others have as well, things in our electronics dealings which go beyond theory and explanation at times. It is never good to "assume" anything when dealing with the unknown. Eliminate all possibilities until the situation is cured. NS |
