I noted in a Facebook post last week that the Chief Engineer at WION would be running equipment tests on daytime power after Midnight EST on Sunday. Testing included a 1000 Hz tone at different levels and lengths.
So! Propagation was good, and from 05:35Z onwards I noted the 1000 Hz tone as it was switched on an off, and at low and high levels. The details were sent off together with a video link to the station. Today, the CE emailed a confirmation of my reception.
I heard and recorded the station with Perseus and Jaguar software, but used HDSDR to get a better view of the 1000 Hz tone. The illustration below shows the tone at peak levels right after being switched on.
Please note: This was NOT a DX Test, hence not widely announced.
