A few files from CQ WW 2014.
All files were recorded within minutes. Amazing to hear 4 bands wide open, Perseus and my active loop were used.and really do perform excellent taking in acount its simplicity.

Daytime 2MHz BW spectrum plots:
Measuring noise power in a 1 kHz BW at 3510 kHz gives -112 dBm and at 2305 -121 dBm some 9 dB quieter.
As most noise seems to be related to switching power devices, I have high hope the noise will be drastically reduced if I move the antenna several 100 meters away. This will be tested ASAP
