I highly recommend this mod, to allow full use of the SDR. Not sure why anyone
would use the I.F. these days, honestly.

Do you have any application
associated with the device controlling the
radio? Also, if you are tuning to a signal
using the dongle, it may be
incorrect with
regard to frequency thus this puts the Omni VII off
frequency. You may need to perform a
Master Reset on the Omni VII.
There are
known some software applications which do shift the VFO,
although not displayed as such on the radio.
This will produce and off
frequency
condition.
I had a a 3
Rivers Dongle on my Omni VII and it worked OK. The
software was a major pain in the posterior to
get running correctly.
Finally I
wrote it off as a learning experience. I then purchased
an
SDR Play RSP-1 receiver and downloaded
free HDSDR software. All issues
resolved
and it works great.
I also
made the mod to the Omni VII for the 2nd receiver which I
find
works even better. With the SDR Play
I can see signals on the entire
band, thus
not limited to the IF bandwidth. That works great as
well.
