G ..


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 ...

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.
