1. [RFI] ignition noise in Chevy engine (score: 1)
Author: Dave N&Oslash;RQ <>

Ignition noise in my 2 year old Chevy Express van is quite bad -- Vortec 6L gas engine. It is worse on 15m and upper HF bands, but still bad on 6m, and detectable on 2m. What would be the best place

I agree that it can be very frustrating. I have had bad power line noise, on and off, for several years. I've written emails, made phone calls, and gotten modest results. When it seems like little wa

Sounds like typical power line noise to me -- nasty, irritating sound, it is! Have you listened to it on 2m or higher? (Not FM, of course.) Often, but not always, it is even louder up there. (Note th

This is one good reason to get a under-the-monitor surge protector, such as the Tripp Lite Command Console (older units are available cheap on ebay sometimes), or some other brand. Don't buy it for t

Thanks for the superb write-up, Frank. I agree with everything that was said, but wanted to add this note... If the power company cannot or will not fix their problems, the normal escalation is not t

Not all GM vehicles are quiet. My 2003 Chevy Express van (with gasoline Vortec 6000 6 liter engine) is very noisy, peaking on 6 meters. A number of attempts to cure it via normal recommended methods

A handheld AM broadcast band radio can be a useful tool, but a VHF and/or UHF radio in mode AM with a handheld Yagi is invaluable in finding offending power line hardware. I feel for you, Ramakrishna

It sounds (to me) like typical power line noise. If it stops when wet (during/after rain, or when dew in the morning), it probably is power line noise. It would be interesting to hear with in AM mode

Absolutely correct. Rain (or even dew, dampness, and sometime high humidity) will lessen or eliminate power line noise. It can be helpful to mention this to your utility, because if they come out whi

I've had the same problem in a big way. IF you can actually find the noisy pole for them -- I know it is really their job -- but if you can do that, it should go a LONG way to helping get it resolved
