DRM+
Digital Radio Sweden
The first field trial phase includes only sporadic trials with DRM+ and has relatively poor coverage. DRM+
reception works mainly locally in the broadcasting area due to a non-optimal antenna placement, and is
limited to a narrow sector over the water directed towards Lidingö/Nacka Strand. Sporadic reception is
possible with a good antenna in the major north Stockholm area. Under the current circumstances in trial
phase one, we cannot recommend listening to or DX our test trials.

During the test phase two, we will have a proper antenna location with good coverage and broadcast
according to a specific schedule. We therefore encourage our listeners to wait until then.

How to receive DRM broadcasts?

Digital Radio Sweden has started test transmissions using DRM technology. These test trials will provide the
basis for technical analysis and are thus at this stage, i.e. phase 1, not primarily intended for the general public
to digest. However, we have received numerous requests and will herewith nevertheless provide some
information on the technical conditions for DRM reception. 

DRM reception
(There are professional measurement receivers available for DRM+, but at a remarkably high cost).
Receiver software (for Android) and a NOXON USB-stick
DRM30
The first test phase includes only sporadic test trials with DRM30 and has relatively poor coverage. DRM+
reception only works locally in the broadcasting area due to a non-optimal antenna placement in a valley,
and is also limited to a narrow sector over the water directed towards Lidingö/Nacka Strand.

However, there are a number of international DRM30 broadcasts available for listening to: See DRM
broadcast schedule at http://www.wwdxc.de/drm.htm or http://www.drm.org/?page_id=151

Excellent DRM30 reception of near-professional class, may be obtainable at low cost using the following
equipment:
DreaM software + FUNcube Dongle Pro+ USB-stick and control software FCHID2.
We can recommend this combination for test trials listening/DXing for DRM30 (but does however require
searching the internet for the file faad_drm.dll, as the HE-AAC decoder dll isn't free for distribution due to
licensing issues. Also required is a good antenna (a long-wire). See http://sourceforge.net/projects/drm/
and http://www.funcubedongle.com/. For FUNcube Dongle Pro+ (FCD) there are many interesting
softwares for SDR (Software Defined Radios). There may however be version issues with the FCD. Please
