LF: T/A May, 10/11 and mystery lines in the T/A window

[Hartmut Wolff <wolff.h@t-online.de>]

High noise level last night. From VO1NA I captured only a "1NA"
00:15-00:30. WD2XGJ was visible 01:40-03:15.

Captures can be seen here:

I added 2 captures of the mystery lines which appeared in the T/A
window. Last night there was only one line. The capture of the night
before is more interesting because there a two lines. Fade in about
local sunset and fade out during local dawn. One of the lines looks
like a sawtooth or triangle.
Any ideas of the source of these lines?
