I can find what looks like construction project.. but is there a
working version anywhere ? or will the ham version take hf broadcast
signals ?

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,

Tnx G ..

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

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.- Hide quoted text -

Ok , thanks for the info,

Im using a racal ra6790gm , which has 20 Khz wide filter, I can set
the bf o up to + - 8 Khz from center frequeny .. so if the signal is a
'12khz block' then setting cw, pass band 20 khz the bfo at either +6
or -6 Khz , that should produce the 12 khz down conversion ? , the
audio bandwith is a littlw over 11 khz , looking of spectrumlab , so
it should handle the signal as 'audio'

I assume the published frequency is the 'center frequency' so setting
the dial at that and the bfo offset to 6 khz , should produce the
correct spectrum ?

Golly. Interesting.

which has 20 Khz wide filter, I can set
the bf o up to + - 8 Khz from center frequeny .. so if the signal is a
'12khz block' then setting cw, pass band 20 khz the bfo at either +6
or -6 Khz , that should produce the 12 khz down conversion ?

Yes. Sounds right to me.
The -6 kHz bfo setting is more likely to be correct
than +6 kHz. With -6 kHz the lowest RF frequency is
converted to the lowest audio frequency. +6 kHz would
invert that.

, the
audio bandwith is a littlw over 11 khz , looking of spectrumlab , so
it should handle the signal as 'audio'

So 20 kHz is the IF width and 11 kHz is the audio width?
I hope the drm demodulator doesn't miss that last kHz.
There is a fair possibility it won't.

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

Tnx . G ..
