tonight the band seems to be plagued by a high level of background QRN. Not the usual distinct static crashes, but rather a continous static crackling reminiscent of old 78-rpm shellack records. This type of noise has been present during some nights, but not often. Its southerly angle of arrival went along well with the usual explanation of very distant lightning activity.

I have noticed similar noise on the band here also during the past few days - the background band noise seems to be ~10dB over the usual levels, swamping the Loran chatter that normally sets the noise floor, but can "switch" on and off over a period of a few minutes. It seems to occur during both the day and night time.

What about a frequency hopping spread spectrum (military) emission?
