K3 & SDR/IQ

Howdy K3' people:

I have an SDR/IQ. I also have three Elecraft transverters. When I
connect a BNC to the BNC-RX "T" chain, and I tune Spectravue to 28.07
and the 6m xv50 transverter is "on", I am looking at the area around
50.070 .. I can look for beacons and Sporadic-E openings.

Nothing new.

However, the other day, I suspected the xv50 transverter to on the
Fritz. So I switched to the internal 6m Rx/Tx section. Made some
contacts.

So now I want to once again look for 6m Beacons down below 50.080 .
My only option seems to be the IF BNC output.

I connected there and tried to set Spectravue for 8.215; 10.0; 28.0 and
still see nothing from 6m. I even tried to set it at 50.10, to no avail.

So how do yu set it up to watch lower end of 6m on the K3, without
using a transverter?

thanks

Connect SDR-IQ to the IF Out jack (not the RX Ant) and tune SpectraVue
to 8.125 MHz manually *or* in SV's "ExtRadio Setup" Select the K3 and
uncheck "HF Tracking Mode."

Note: If you want to use the frequency tracking tied to the IF, you
will need some kind of serial splitter to share the K3 serial port.
For more information see the SpectraVue Help file section 4.2, page
59 and page 58 "IF Tracking".

In reply to this post by Bob KD7YZ

You don't say what software you are running but if it's Spectravue, just go to the ExtRadio tab, select the K3 from the drop down list, set the com port, baud rate and check mode tracking. In the SDR-IQ setup, set the filter BW to 100 or 150. Press F12 and you should be in business.

LP-Bridge will handle the serial port issue. I run the K3, Spectravue, DXBase and N1MM with one USB to Serial adapter and ports to spare.

Maybe - if none of your software uses one of the commands that
LP-Bridge blocks or modifies. The N1MM Logger support team will not
even accept bug reports if LP-Bridge is involved - any bug must be
duplicated and documented with LP-Bridge removed due to the known
issues.

Re: K3 & SDR/IQ

SpectraView's HF tracking mode doesn't allow for an IF tuning offset on frequencies higher than the design limit of the SDR-IQ itself. I know the IF frequency is well below that, but the software was never supported "tracking panadapter" operation on 6M to the best of my knowledge. You can still see the IF spectrum, but you won't have a operator-transparent tracking ability.

See the Yahoo SDR-IQ group thread on the topic here:

Fortunately, that information is incorrect. I just retrieved my SDR-IQ
from the shelf, connected it to the IF loop on my P3, loaded SpectraVue
set the External Radio/Panadapter Setup as recommended in the SV help
file and was running with a "tracking panadapter" on six meters.

I used the 2nd CAT port capability in microHAM USB Device Router to
provide the serial splitter function and the K3 tracks clicks in the
SV spectrum/waterfall and SV tracks frequency changes from VFO A on
the K3. Operation is the same on 6 meters as on 160 through 10.

The only issue is the constantly changing IF offset in the K3 (IS)
which SpectraVue does not track. This results in a variable frequency
error based on mode.

Re: K3 & SDR/IQ

It didn't at the time that I sold mine - it would simply "top out" at 30 MHz. Thanks for the update.

Not if you connect via USB.

Re: K3 & SDR/IQ

I use SpectraVue as a panoramic adapter with my K3 and three XV transverters. Connected to the K3's IF out is an SDR-IQ, which is connected using the USB port to my PC.

I don't have any issues with a 'variable frequency error' on 6 meters or any other band. I can point and click to a signal on the monitor and the K3 will follow, and vice-versa, regardless of the band or modes.
