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.
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.

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.

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

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
