SDR-IQ users?

Looking for some assistance in setting up SDR-IQ. I ran the setup and
connected the IQ and it is receiving sigs from the K3's IF.

The problem is I cannot get it to communicate with the K3 to follow
frequency changes from the radio....or when clicking on a signal to
have it change the radios frequency.

I would have thought that after the setup I would find something for
the SDR-IQ in the device manager but I don't.....no com port setup for
it or anything. Did I miss a step somewhere?

THanks

Re: SDR-IQ users?

Start up SDR. Then push the setup button and the cat submenu button when it
comes up. You'll then see a choice of which com port you wish to use along
with the other parameters that are necessary to be set up. That should do
the trick.

Re: SDR-IQ users?

Thanks Bruce. It didn't but that's because I don't have the K3
connected directly to the SDR-IQ.

What I had to do after some trial and error was to go to the USB
device properties and tell it to set up a virtual com port (in device
manager). Then I set LP-Bridge to the same port and restarted
everything.

Now after a little tweaking of the IF freq and zero-beating with a sig
generator it seems right on and tracks/controls the K3 fine.

Re: SDR-IQ users?

So gentlemen what is the real difference between LP-PAN and the SDR-IQ?
Seems like the main diff that I'm seeing is that one has the "sound
card" built into it....

Any other thoughts?

Re: SDR-IQ vs LP-Pan

In reply to this post by Greg - AB7R

I think you guys are talking about 2 different products. SDR-IQ is made by
RF Space. It's not an LP-PAN. It would be nice to have an in depth
comparison between these units. I do know that the IQ has no direction to
the K3's comm port and no dedicated sound card but that's about it.

Re: SDR-IQ users?

In reply to this post by Brett Howard

Neither the SDR-IQ or the LP-PAN have sound cards in them.

The SDR-IQ is an full blown SDR receiver which does the data conversion
onboard then sends the results to the computer via USB port. The SDR-IQ
converts the entire spectrum from 500Hz to 30MHz to IQ data at an 67MHz
sample rate.

The LP-PAN is an IF to computer interface. It takes the data off the K3
IF port, at 8.215MHz, converts it to IQ data, and sends it on to the
computer sound card which samples the data at a 192KHz rate (for better
than average sound cards).

The LP-PAN/E-MU 0202 combo, which seems to be the sweet spot, are just a
little more than half the price of the SDR-IQ.

That's not correct. LP-Pan = $225 (assembled), E-MU 0202 =
$199.95 (list) ... total $425 vs. $499 list for the SDR-IQ.
The difference in "street" prices will vary significantly
deepening on shopping skills and the availability of used or
kit options.

LP-Pan with the E-MU 0202 (USB) soundcard, LP-Bridge and
one of the PowerSDR versions are resource intensive for
the computer. SDR-IQ/SpectraVue have much more reasonable
CPU requirements.

Unlike PowerSDR, SpectraVue will operate in a Window and
can provide simultaneous spectrum/waterfall displays.

Although not important here, SDR-IQ also supports a broad
range of non-Elecraft transceivers.

Hallo Greg,

using SDR-IQ with SpectraVue 2.34 you dont need a virtual com port - in the SDR-IQ setup menu you must only select ext radio=Elecraft K3. Try SpectraVue 3.0 Beta 30, there are some more option as in 2.34.

Re: SDR-IQ users?

In reply to this post by Joe Subich, W4TV-4

Just checked one of the largest online computer parts retailers,
newegg.com, and they've still got the E-MU 0202 selling for $99.99, same
price I paid for it 6 months ago so I wouldn't expect other online
retailers to be higher or lower than that by more than $5.

So, $225 + $100 = $325 or $175 + $100 = $275 for the LP-PAN kit plus
E-MU, compared to $499.99 for the SDR-IQ at Universal.

The E-MU is processor intensive but runs real well on any machine 2
years old or newer.
You won't be running this combo on that old PIII with USB 1.1 ports
sitting in the corner but I'd bet the SDR-IQ wouldn't work real well
with that kind of machine either.

Another way to get around the resource sensitivity of the E-MU 0202 is
the Infrasonic Quartet PCI internal sound card for $139.99.

Larry is now making versions of the LP-PAN for these rigs and IF
frequencies.
8.215 MHz (Elecraft K3)
8.83 MHz (most older Kenwoods)
9.00 MHz (TenTec Orion)
4.915 MHz (Elecraft K2)
10.7 MHz (IC-R8500/9500 and others)

Actually, while it can be tuned over the 30 MHz range, I believe it only
down-converts about 200 kHz at a time.

SDR-IQ runs very well on a 1.8 GHz/512 MB single core P4 class laptop
that is brought to its knees by PowerSDR and an E-MU 0202. There are
a lot of sub-2 GHz singe core systems in ham shacks.
