Bird Calls? 0438 UTC 6930 USB 22 May 2016

SDR recording catch. I wonder if this is related to what has been reported in Europe being heard on the Twente SDR? http://www.hfunderground.com/board/index.php/topic,28172.0.html

Here is a recording of what I heard, only on for about a minute: http://radiohobbyist.org/blog/mypics/6930.0-USB-22-May-2016-04.38.04.mp3

3+ years ago, I heard something similar on the Univ of Twente WebSDR:
http://www.hfunderground.com/board/index.php/topic,10205.0.html

Haven't thought about it until you posted (oddly, I thought I heard it last summer, not 3.25 years ago).



0156Z 45444 S9 Bird calls with a cuckoo going strong. I vividly remember the cuckoo from the previous time I heard them.
0207Z Dropped from around -70 dBm to right into the noise (-90dBm). Weak carrier visible and no audio is heard. Station is gone for tonight.

While listening on the U Twente's WebSDR, also listening for a carrier on my radio, but never heard anything.
