i called this a pan adapter but its more of a spectrum scope.___

Hi Carey:
I did exactly that a few years ago with my a version. It works really
well and is a excellent way to get involved with SDR, the Software, and
get a panadapter along the way.
You need to get the proper IF version softrock. The SDR needs to be
tapped off of the 1st IF before the

I guess I'm missing the objective here. I have several SoftRocks, Ensemble, etc., and the biggest
'feature' they offer is the ability to see large chunks ( 48, 96 or 192 kHz ) at a time. If you tap
off in front of the roofing filter, 5.645 MHz 1st IF, all you are gaining is an RF
Hi Garey:
Yes points well taken. In my case, I did this before the ensemble was
available. Had I had that availability, I would have chosen to go that
way as well.
It does work well tho. I didn't see much of an issue at all with the
limitation from the preselector. In practice, I was
Curt -
OK. Nothing wrong with FUN!! :-)
If you're only looking for a 5 - 10 kHz window, then the Preselector won't be a problem except
perhaps on 80 / 40M. It's not a steep skirt, so would still be useful further out.
The Ensemble really is a cool little receiver. Tony and the rest have

But..does it track with the tuning of the R-4C?
Why would ya want to tune 2 RX's at the same time?

The preselector is the limiting factor as Garey pointed out. The problem
is worse on the lower bands, especially 160m. You would need to tap ahead
of the preselector -- essentially at

outstanding job!
For many years, I tried to order a Softrock kit, and now the Ensemble Tx/Rx.
In every single instance, the kits have been unavailable with a check back
soon! message. I checked again today, and

the R4 and also provide frequency data to the SDR control

The demand seems to be so great that one must follow the Softrock yahoo
group for when the board stock becomes available and then place the order.
BTW, taking signal pre-preselector means that you no longer have a fixed
post-1st mixer signal and therefore the SDR needs to be tuned all the

Lee -
I don't have precise figures on Preselector bandwidth, and of course it
varies
from band to band.
But it's a LOT less than 70 kHz, even on the low bands.
I think this will be the limiting factor of bandscope coverage. If you
want to
look right around
Paul -
The 7 is a lot more amenable than the 4. It has wideband filters in front, so the first real
selectivity is the 45 MHz roofing filter. Each BAND is much wider than usable by the SDR.

Hi Garey, Curt,All,
I was thinking to do the same, assuming the preselector would have a
(much) wider pass-band!
Is it really that narrow, only 20 kHz ?
In that case I think it could be that the reception in the Softrock
would benefit a lot from such good preselection! ;-D
But that's not
Henry,
I for one...am interested in the outcome.
Time for a fun, inexpensive project here. Hi, Hi,

Curt,
Please give a complete description on this whole thing..I am not
familiar with the SDR stuff at all.
