Well, this weekend is the CQ World Wide DX Contest, one of the larger contest weekends. I tuned up to 15m, around 21.259, and found HC8A booming in. Months ago, my 40m direct conversion receiver was initiated with reception of an RTTY signal from HC8N. Both are stations located on the Galapagos Islands. Nifty. Here’s a link to a brief MP3. You can also hear a Costa Rican station operating on the same frequency for the first half or so, then he moved up in frequency a bit.
Contest exchanges are kind of boring (well, to be fair, REALLY boring) but contests do bring out large stations with lots of power, and allow you to hear zones of the earth that are largely quiet from inactivity.
