This news just received from Dave Porter:
The BBC and Encompass Digital Media are running Simulcast DRM and AM test transmissions on 1584 kHz from the aerial mast that previously carried Radio Hereford and Worcester, at the Woofferton shortwave site on the Shropshire/Herefordshire border.

The BBC point of contact is Robert Webber who has provided some information to Dave Porter:
There is a mixture of SCS (Single Channel Simulcast – AM and DRM in the same 9 kHz channel) and plain old AM being transmitted at various times throughout the day.
Power is up to 1 kW, the antenna is the former 1584 kHz Radio Shrops and latterly H&W one. The test transmissions are being carried out under a Test and Development licence from Ofcom.
We are looking to start to operate 1584 kHz in simulcast from Tuesday 19th April.
Hours are 09:00 – 17:00 BST [0800-1600 UTC] as per the licence.
Reception reports are welcome and should be sent in the first instance to transmissiontest@gmail.com

Checking at 1440 UTC today on an SDR in Shropshire I can confirm that tests are already in progress on 1584 kHz, currently with music and frequent announcements in AM.
