We are pleased to report successful use of an SDR Dongle used to directly receive and Decode DRM 30 over HF today.
The SDR Dongle is an RTLSDR v3 type connected to an android smartphone using an OTG cable (phone or tablet must be OTG capable).
The Software used:
1. Android driver (free)
2. DRM+SDR Android App ($4.99)
The Frequency of the HF broadcast is directly assigned within the DRM+ SDR app with two settings
1. Frequency in Hertz
2. RF Gain (0-512)
Demonstration video showing Clean DRM decode of AAC Audio and Journaline data along with live metadata. (our signal was very strong, so only a short wire used for Antenna, DX'rs will need an appropriate Antenna)
** Updated 01/28/2020, SDRPlay type SDR has been added
Now anyone with a smartphone and a $20 SDR can receive DRM 30 HF broadcasts...
