Hello Mike: I believe that the 1820 spurs are created from multiple sources. That is why you can hear it at many QTHs around the world (although the spur content is technically different with respect to the origin).
There are 57 different licensed AM broadcast stations in the USA and Canada that operate on 910 KHz. Most all of them are operating within licensed parameters with respect to second harmonic radiation limits. Topband stations are best to avoid operating directly on 1810, 1820, 1830, etc. for this reason. 73, Tim K3LR -----Original Message----- From: Topband [mailto:[email protected]] On Behalf Of Mike Waters Sent: Friday, November 02, 2012 9:17 PM To: topband Subject: Re: Topband: 1820 spur It can be heard in Japan and Canada?!
