Hi All,
For about 7 days or so I have been getting some
very strong interference on the 136kHz band. At first it only came on for short
periods (up to 1 or 2 hours) but from yesterday it came on early evening
& stayed until early today & is there again tonight.
The interfering signal sounds like a buzzing noise
on my LF Rx & the visual display shows a very unstable form. It starts from
about 137.000kHz upwards & fades towards 145kHz.
I have placed 3 captures on Dropbox, 2 SpecLab
(showing the start time) & 1 HDSDR showing the extent of the
interference.
If anyone can identify this type of interference I
would be pleased for comments. I believe I have eliminated all my own gear &
household items.
Thanks & 73,
Gary - G4WGT.
