Probably not because of the codec licensing issues and also because the DRM
standard was not the US system, there is also - IBOC which is more common in
the USA. There are two rival systems out there and that is never much good
for adoption.
The K3 is not intended to be a broadcast receiver. It h

Having been tuning around 6MHz and enjoying greatly the P3, I rediscovered
the existence of DRM. I read some time ago that DRM was dead in the water,
but notwithstanding, there does seem to be a significant number of stations
out there broadcasting. Susan mentioned this sometime ago I believe, and

I'm confused. What "20 kHz bandwidth" are we talking about? The output of the
detector? Are you s
Could the 8.215MHz output from the IF OUT jack be fed to a simple mixer
with a 8.203 or 8.227MHz crystal to provide a 12kHz i.f.?
I have used this method very successfully on the Sangean ATS-803A and
Lowe HF-225 receivers with both DReaM v.1.6.1cvs and DRM Software Radio
v2.0.38 programs. But

DRM decoding with the K3 is easy with the SDR-IQ together with SpectraVue,
VAC and DReaM software
In general, DRM decoders expect a receiver IF of 12 kHz and a bandwidth
of up to 20 kHz. The K3 can provide neither without modification.
Some DRM modes are narrower and can be accommodated if the FM roofing
filter (nominal 13 kHz) is installed. But getting the IF output to the
DRM decoder st
I am not sure if the 13kHz FM filter is wide enough, but if it is, your
suggestion should work. I didn't have the FM filter at the time. I think
PowerSDR allows 15kHz for its DRM mode and it may have less group delay
distortion than the crystal filter. The decoder is finicky.

Some of the programs you mention would appear to be un-necessary. If the DRM

Hi,
Yes, I have been using the K3, LP-Pan, PowerSDR, Virtual Audio Cable and a
free decoder program called Dream. It was quite a while ago and the
experience wasn't that great. The slightest fade and the decoder would lose
the signal. Also, there are precious few DRM transmitters that can be hea
Now that I'm enjoying SWLing again, I'd like to try to "decode" Digital
Radio Mondiale. Has anyone succeeded in doing this without buying a
purpose-built DRM receiver?
