As of 0535-0600 UT:
Supposed to be Chadienne SW station was using 7288 to 7292 kHz range in past four weeks.
But today - June 11 - observed in 7309 to 7320 kHz range again.
Station Wandered around - moved UP from 7309 to 7315 kHz, but was on back way DOWN
to 7312 kHz 'center' around 0535 to 0550 UT. And hit also RNW Flevo signal
in 7310 to 7312 kHz portion then, when checked and using a 4 kHz wide filter
on the rx set.

CHAD 7312 to 7318 Checked this distorted audio station (Chad?) today June
11 again. S=7 signal noted this morning on 'unpleasant' time for European
audience. 7290 kHz was free channel at 0440 UT, so I checked the 41 mb in
total. But a highly distorted audio signal observed wandering in 7312 to
7318 kHz range between 0440 and 0510 UT.

7309-7314 at 0440
7311-7316 at 0455
7313-7318 at 0505
7315-7320 kHz at 0510 UT.

Hit heavily WHRI program in English on 7315 kHz, but let nearby RNW Flevo in
Dutch on 7310 kHz in the clear from 0500 UT.
