[Elecraft] K3 Spur on 160??!!

[Milt -- N5IA]

Mike,

>From my remote station which was operated by KY7M in the contest, I noticed 
the same thing from the AC0C RBN box.

However, in this case the QRG of KY7M was 1.820.6 and the other recorded 
transmission by AC0C was 1.864.7, a 44.4 kHz difference.

Your noted difference was 25.4 kHz.

Perhaps someone smarter than me can figure it out.  BUT, I am sure the 
problem is with the AC0C receiver and NOT our K3 transmitters.

73 to all de Milt, N5IA

Subject: [Elecraft] K3 Spur on 160??!!

After the CQWW 160 contest this past weekend, I checked my signals on the 
Reverse Beacon Network and it appeared that the AC0C skimmer (545 miles NW 
of me) was picking up a spur on 1855.7 kHz! This occurred only at the AC0C 
skimmer and did not show on any other skimmers and only when I was running 
on 1830.3 kHz and did not show when I was running on any other frequency. I 
have done a cut-and-paste below. I was using my K3 barefoot and my antenna 
is an inverted L with one elevated radial up 20 feet.

Is this something I should be concerned about?
