Rusian OTH 80m 24*7*? WSPR wrong band report

Image
Since a few weeks the Rusian OTH radar is active again 

Covering the 200Hz  WSPR  window at 80M     3594.1 kHz 

WSPR screen looks like this

 The straight horizontal lines indicate  a very stable frequency base better then 1hz.
WSPR shows the slightest frequency drifting or Doppler effects during Aurora very clearly.


It sound like this :

Not that we will loose DX there simply are no DX decodes last weeks to east.  Except some rare USA in the morning at 80m.
160m  best DX  is not even over 1000km.
The season is closed ftb. 

WSPR  using  band hopping  sometimes reports the wrong band.
This usual happens when  manually switching band.
Band hopping then seems to loose track of the band to report. That is what I experience.
Tonight this happened again but this time I was not at the radio.  Band-switching   4m and 80m  was checked.
I saw this when coming back in the shack:
2138  -7 -0.5   3.594112  0 DK4XI JN39 37

2 false reported on 4m 
2142 -23  0.9  70.092460…
