Before complaining, it would be a good idea to be absolutely sure your own system isn't causing the QRM. Some of the hardware commonly used in receiving systems is pretty poor; /archives//html/Topband/1999-12/msg00307.html (8,148 bytes)
2. Topband: BCI (score: 1): Author: gary@noblepub.com (Gary Breed); Date: Tue, 28 Dec 1999 15:38:26 -0500; Tom has given us some excellent suggestions. Let me also suggest using a SPECTRUM ANALYZER to identify suspicious signals. There are industrial sources of tens of kW at 6.78, 13.56 and 27.12 MHz that; /archives//html/Topband/1999-12/msg00311.html (7,439 bytes)

Topband: BCI (score: 1): Author: "Scott Long" <k8sm@windstream.net>; Date: Tue, 13 Dec 2011 17:36:23 -0500; A strange happening already this season, I am hearing WTVN-AM 610 khz (Columbus OH) plain as day on 1830 khz. This is the only frequency that I hear it on. I am at least 35 miles from this station, a; /archives//html/Topband/2011-12/msg00329.html (7,110 bytes)

This happens all the time. If you tune around between 2 and 3 MHz, you will often find a handful of broadcast harmo; /archives//html/Topband/2011-12/msg00331.html (6,763 bytes)

Re: Topband: BCI (score: 1): Author: "Tim Duffy K3LR" <k3lr@k3lr.com>; Date: Tue, 13 Dec 2011 17:01:31 -0600; Hello Scott: Lots of things can cause your receiver to hear the third harmonic of an AM broadcast station. One of many reasons - could be the broadcast station - but is the most unlikely source of th; /archives//html/Topband/2011-12/msg00332.html (8,702 bytes)

Re: Topband: BCI (score: 1): Author: "Joe Subich, W4TV" <lists@subich.com>; Date: Tue, 13 Dec 2011 18:28:23 -0500; From personal experience, WTVN-AM has had third harmonic issues going back as far as 35 years. Remove your receive protector and check other antennas to be sure the "harmonic" is still there. Also tu; /archives//html/Topband/2011-12/msg00333.html (8,159 bytes)

I thought it was birdies but realized it had an external component when I removed my antennas and they went aw; /archives//html/Topband/2014-03/msg00025.html (9,202 bytes)
8. Re: Topband: BCI (score: 1): Author: Don Moman VE6JY <ve6jy.1@gmail.com>; Date: Tue, 4 Mar 2014 02:35:36 +0000; It is unusual for AM BCB signals on a 10 khz raster to produce signals every 5 khz. It is relatively simple to insert a MW rejection filter in a RX ant loop which should alleviate or cure the problem; /archives//html/Topband/2014-03/msg00027.html (10,536 bytes)
