Because of the wide front end filters, some have reported front-end overload issues. Software/firmware updates will not fix this as it is an inherent issue with wide front-end filters: nearby BC or amateur stations can swamp the front end and the rig sensitivity nosedives. As long as the overload does not occur it is a fine rig. I can see no good reason why this rig should be any worse than others that use sub-octave filters rather than narrow bandpass filters for each amateur band. Such designs are common nowadays in front ends.
I think sensitivity starts to collapse if the rig sees more than 70mV in the front end. If you have a nearby 1kW station operating in the same band, you could have problems. You might also have problems with multiple very strong BC band stations.
Although without 2m and 70cms, the European version does have 4m, which is good. I still just prefer the IC7300 to the Yaesu FT991. The price needs to drop though!
Eham reviews point to an overload in the front end:
