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:

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.
