An external Interference has been detected in EW Drift experiment. This doesn´t allow the correct automatic calculation of the Drifts.

For the main Antena 2 pre-amplifiers are used.
For the Hysell module 4 pre-amplifiers are used.
Channel B (EDW RX) and C (NS DW) point to the West, Channel D (NS UP) doesn´t see it, points to the East.
It has been seen since July 11 2016.
After the September 29 to October 1 campaign, an interference in the 1 MHz band was found it was on 50 MHz, this interferences is generated by JRO.
