Hi John, I had this happen to me a few days ago where I was calling CQ on 7.015 and was spotted on 14.0614 by Tim KQ8M's skimmer. I emailed KQ8M to ask him if there was a problem with his skimmer. He replied that he wouldn't rule out that the problem was in his Rx setup, but it was tuned to 20m.
Now I was running through the linear and an ATU, and I can't see any logical relationship between the two frequencies, so I'm leaning to the theory that his receiver was the culprit, although I did find it very strange. I think a lot of RBN skimmers use SoftRock receivers, and I'm guessing that if his VFO was tuned to 14.050 using the 2nd harmonic of a 7.025 fundamental, it would kind of fit, but I'm still surprised that my 300W signal to an inverted V was 6dB over the noise on the wrong band in Ohio, 3800 miles away on the other side of the Atlantic... I'm not sure exactly because I don't know what receiver he was using, but it did have me puzzled and when I saw John's post I thought I'd mention it.
