I've tried searching a dream.zip ...
it works.
I've tried it with a sw radio, no drm, I do not know how one can
receive drm
with eg a Sony 2001D, and no drm module, but it seems possible ...

Ok...
Yes that worked .... seems to run , dident think of that ... the rx
has a 20 khz wide filter so should be able to take audio direct,

So much for that bright idea .nothing yet ....
.. the 12khz talked about , is that the center frequency of the
translate audio spectrum ???
so your supposed to present 0 to 20 / 24 khz to the sound card ????
and 12khz is 'the dial frequency' ???
Tnx
G..
You need to down convert the 12 kHz width of the
transmitted signal down to 0 to 12 kHz for input
to your sound card.
It won't work with the receiver in AM mode. An
AM detector destroys a drm signal.
SSB mode would work if the SSB receive bandwidth
were 12 kHz. I've never seen an SSB receiver with
12 kHz bandwidth other than the TenTec RX-320D
or similar SDRs. I don't know about Sony, Degan,
Sangean, etc. receivers but I doubt they can do it.
You might try with whatever SSB bandwidth you
have but I would be surprised if it works.
The PCR1000 will work.
Set the IF to 50KHz and feed the audio into a PC running Dream.

Well not a beep
I can see the converted audio spectrum 0 11/12 Khz on the screen ,
lots of flashing red , sometimes yellow , inicators on the traffic
lighs , but never a full set of green ones .. tried all the sig's i
can pick up , maine ones round 6 mhz ....
looks like maybe the audio needs to be centered round 12 khz and not
zero to 12 ? .... if your running one of these 'add on' if
convertors , where is the main bulk of the audio signal , when you
view the 'spectrum display' center or biased to the left ...?
As the display gos upto over 20 khz , i suspect , the audio must be
centered round the middle , ie 12khz , in which case, it will not be
posible to use the rx , as is, however it dose have a 455khz if
outlet .. next step get one of these little down convertors ... any
good link's
