Strange Problem With HT - Help!
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! |

Sometimes the outlets are wired to each other and as current is drawn from them they can cause problems. |

Makes a GREAT little vertical antenna -- great for coupling RF from your nearby vertical antenna. I'd take the vanity plate off the outlet, darken the room, and re-create the scenario you explained above. Get in close and see what is arcing, buzzing, spitting. As others have said, it's pro'lly a loose connection.

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. -- Dave Platt AE6EO Hosting the Jade Warrior home page: http://www.radagast.org/jade-warrior I do _not_ wish to receive unsolicited commercial email, and I will boycott any company which has the gall to send me such ads! |

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.

I have an Extra Class License but this isn't in the books :-( Thanks in advance! Since it has worked for 11 years without a problem, my guess is, perhaps something has changed in the antenna system. Perhaps a loading coil has given up the ghost. Maybe the kitchen window has been opened and closed on the coax a few too many times and has destroyed the braid, broken the center conductor, or just mashed it to where it is making some sort of impedence bump in the feedline. You mention the buzz is coming from an outlet in the kitchen. I suspect this is a GFCI type outlet that is required by code anywhere an electrical outlet is near a sink or faucet, etc. What I am suspecting is, your coax is now radiating a signal instead of delivering it to the antenna and the RF is getting into the GFCI circuitry in the outlet. I would- (1)-Check SWR on the entire system. If you have high SWR, try replacing the antenna. If that doesn't solve the problem, then the problem is most likely in the feedline and that will need to be replaced. (2)- Visually inspect the feedline for wear, distortion, etc. (3)- Try routing the feedline differently away from the outlet if possible. I am curious, how much feedline you have between the transmitter and the antenna. Since you mentioned the radio was in the living room and went out the window in the kitchen, I am going to guess you have at least 30-40 ft of feedline. I am also going to guess that you are using RG58 type coax since it is going through a window. If this is the setup you are using, you are losing a LOT of signal just getting the tranmitted signal to the antenna (assuming you are using VHF). If you are using UHF, its even worse. I realize you may not have much control over where you put your radio or antenna, but the less feedline you have, the better off you will be, especially if you are running low power levels such as from an HT.

Thank you, everyone for helping me. The handyman just came up. I could
have sworn I tried this with nothing plugged in but the hair dryer seems to have been the problem. There's a reset button which was off (when you turned the dryer on, it stops it from working), When this button is off, the socket buzzes when I key the HT. When the button is reset, no buzzing. We tried it in another kitchen outlet and it did the same thing. So it's not the outlet that needs fixing. What's happening technically is beyond me. If anyone understands this, I'd appreciate an explanation. I am wondering how much of this may be due to old coax. I'm careful to not crush it...the window is never tight, I always leave a space. |

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 Agreed - so isnt the simplest, least most blatantly obvious thing to do is physically examine the offending object. Andrew VK3BFA NO, because parts which are being activated by RF won't show signs of anything outward, such as being blown. Things are not always OBVIOUS. There is nothing stopping one from looking, but RF induced troubles are virtually invisible until you figure out HOW the RF is doing it's magic. NS |

... Thank you, everyone for helping me. The handyman just came up. I could have sworn I tried this with nothing plugged in but the hair dryer seems to have been the problem. There's a reset button which was off (when you turned the dryer on, it stops it from working), When this button is off, the socket buzzes when I key the HT. When the button is reset, no buzzing. We tried it in another kitchen outlet and it did the same thing. So it's not the outlet that needs fixing. What's happening technically is beyond me. If anyone understands this, I'd appreciate an explanation. I am wondering how much of this may be due to old coax. I'm careful to not crush it...the window is never tight, I always leave a space. Your coax does NOT have to be broken, to create RF troubles. When you transmit, the signal from your antenna is getting into the circuit which most likely isn't shielded against such things, and is playing havoc with it. THAT HAPPENS....... RF does strange things....... NS |

Well, I know the "Fault" was found in this case... Now, why did it buzz? Do you really think anything is going to jump out and say - here I am? I doubt it. RF with anything in electronics, needs "Experience". THAT keeps you from wasting lots of time guessing. You get a feel for the problem, a sense of direction and follow the leads. People who GUESS and waste time doing so, ARE NOT EXPERIENCED. Back to the fault, not having it here to visualize, I can't say for certain, but I'd bet a lack of shielding had a major role in it. The "'triggering" circuit most likely was being affected, somehow. RF doesn't always have to make sense. But if you narrow down the parts affected and know that RF was the cause, then you can work towards a cure to keep it from happening again. NS Nah, your talking total crap! - confused by trying to do this by remote control and getting lost in your own brilliance..... Experience is the name for seeing the same fault before, a feel for the problem is making a link to something similar. But I can guarrantee my method would have werked - why, because I would have checked it was the socket and not something else attatched to it that was buzzing. - as the home handyman did - perhaps he is an experienced electronics engineer like you suggest who called upon his "experience" or maybe he just looked for the blatantly obvious! And if a $10 hairdryer is suffering RFI - big deal, dump it in the bin, or press the reset button. No complex theory involved here sonny. Have you had 20 years experience, or the same year 20 times over....... Andrew VK3BFA |

Just to add to this, I plugged in the toaster, the microwave oven and
several other appliances and the only thing that caused the socket to buzz when I key the HT is the hair dryer which is on OFF (but not reset). When I pushed the reset button with the hair dryer still off, the socket didn't buzz. I would like to understand exactly what internally in the socket is causing that buzz which is extremely loud. Does anyone know? Thanks for your responses to my thread. |
