Woofferton will be carrying out some DRM transmission tests over the
next couple of days. The transmissions are the first on-air trial of a
remote learning solution that will eventually be deployed to The Gambia.
The idea is that a lessons can be delivered using the Audio Service to
send speech created by a teacher, while the supporting text and
picture-based information will be delivered in the same 10kHz wide
channel using the Journaline service.
The initial receive equipment being shipped to The Gambia will be an
Android device with an SDR and loop antenna. The StarWaves DRM SoftRadio
app will handle everything from demodulation to presenting the audio and
Jounaline services. For anyone with access to the StarWaves app I'd
recommend it as the easiest way of receiving DRM, although if you
already have Dream up and running then this too should do good service.
The caveat is the the Audio will be using the xHE-AAC codec, which can
require some extensive tinkering to get working in Dream. Even if you
don't have the ability to decode xHE-AAC, the extensive Jounaline
component should still be copyable.
The transmissions will take place Thu 28 and Fri 29 June at the
0630 - 0700UTC: 6195kHz 114°
0830 - 0900UTC: 9410kHz 92°
The transmission tests are being carried out by Encompass Digital Media
who do not have an official QSL policy. However, I'd be interested to
hear if anyone succeeds in receiving the transmissions, and would be
more than happy to confirm reception reports via email.
