OT: Request for EMI/RF Interference Opinion
Locked
 
|
Hello, I'm looking for someone with some background in EMI or RF interference to look at some very odd noise I am experiencing on 15 meters (it is heard on my K3 and KX3). I can send a spectrum analyzer screen shot and a small audio file to help. After trying all the usual things and having no luck I need to get some opinions from someone with more experience; thanks! --Ed-- --- This email is free from viruses and malware because avast!

Ed,
First off, lets get some more specific info on how far out of the noise, stationary or moving, time of day etc. Whether you are in a rural area, down town, in other words, the electronic environment you live in. I would love to see the screen shot, and an audio file will fill in more gaps. Sorry you have the problem, but it is the modern times we live in.

I say, put batteries in the KX three hook up a small piece of wire and walk around with it. Watch the estimator and find the noise peak and what it comes out of.

Somebody on this list once sent a link to a page that has recordings of all sorts of RFI sources. I used it to track down an ultrasonic "pest repeller" that drives me nuts on 6m. If I can find it again I'll send it on. It may have been an ARRL page.

You're thinking of this: http://www.arrl.org/sounds-of-rfi

The ARRL has identified and unidentified noise files at
www.arrl.org/sounds-of-rfi. The old VE3HLS website doesn't seem to be around anymore. 73 On 12/3/2014 6:27 PM, Mel Farrer via Elecraft wrote: > Good input.

There's also a website where you can hear what all the new and old digital
signals sound like. Sorry, I forgot what it was, but it should be easy enough to find. I'm still wondering what those "weebles" signal are on 10 & 12 meters. Now that I have a waterfall display, they're easy to spot. They typically start high in frequency and end abruptly, some moving very fast and some slowly. Probably just a Barsoomian invasion fleet. 73, Charlie k3ICH ----- Original Message ----- From: "Steve Glickstein" <[hidden email]> To: <[hidden email]> Sent: Wednesday, December 03, 2014 6:43 PM Subject: Re: [Elecraft] OT: Request for EMI/RF Interference Opinion > The ARRL has identified and unidentified noise files at > www.arrl.org/sounds-of-rfi.

I am afraid that this way you will get a lot of birdies originated from
KX3 itself. This is especially the case on 2m using an attached SMA whip. Any other experience or info on the way tu cure this!? 73's.
