There is a new Yahoo group http://groups.yahoo.com/group/RFICausedBySDRIQ/
which may be of interest to those who own or may purchase an SDR-IQ. The
purpose of the group is to exchange information about RFI caused by the
SDR-IQ and how to reduce or eliminate the RFI.

OK. What's 'SDR-IQ'?

Even with the link; it still makes little sense;

Why the hell don;t these guys tell us SDR stands for Software Defined
Receiver..

receiving Sonar and Sound ? Listening to Bats ?

- Why post here..

Who are these guys selling this thing to ?

Thanks for the 'Software Defined Receiver'. I suppose it's obvious to
those in the know.

Being an analogue sort of person, I'm a bit of a dinosaur when it comes
to these newfangled devices, but it certainly looks interesting.
Unfortunately, all things digital tend to generate radio frequency
interference, and it takes a lot of design skill to make them usable.
Undoubtedly, the designers of the RDF-IQ will have taken this into
account.

As this is the rec.radio.shortwave NG, it makes perfect sense to
publicise this 500Hz to 30MHz receiver here. Free samples to all our
readers?

Well the humble little TenTec RX320D on my desk doesn't seem to
generate any irritating noise. It just does its job reliably and
without complaint.

Yes, I see that it gets very good reviews. Lots of 5 out of 5 in Eham.

Is it interfering with itself or other devices.

If it is interfering with itself it is perhaps not surprising.
It is an interesting looking gadget but it is not a radio.
It has no front end. It is open to the whole 500 Hz
to 30 MHz all the time. If you have a strong AM broadcast
station near by or a ham or CBer in the neighborhood
their signal will override everything else. The SDR-IQ would
make a good IF/back end. Better results would be
obtained by connecting the SDR-IQ to the IF of another
receiver. Or by putting an RF preselector in front of it.

The TenTec RX-320D is about the same price but has a
real radio front end. Unfortunately the TenTec has
an RS232 rather than USB interface and the TenTec only
has a 12 kHz bandwidth.

Baker, you are obviously judging from assumptions and not facts. Of
course it is a radio. Make an internet search on the different SDRs
available and user reviews. You may be surprised.
