Hello, Can someone please post a *.wav file of what it sounds like provided you have an SDR set-up?
If you need someplace to post - please send the file to me offlist and I'll put it on either an ftp site or http. I am not so convinced what I saw wasn't noise or some stations from China transmitting - which I have seen in the 160m band lately. I got an AM band tonight also that was stomping all over ~ 3.87 MHz. Thanks!
