But this radio performs VERY well, in my experience (and I actually own the radio, unlike many commenters here). It actually out-performs my IC-7300, in the city, due to its far superior noise reduction, a trickle-down from the FTDX series. The spectral purity was an issue mentioned. It was also mentioned by the test engineer that if you run it at 50w (30w digital) or under drive power, you won't have any troubles with spectral purity or phase noise. So, if you amp it, probably best to have it be an amp that drives at 50w or less. http://radioaficion.com/news/yaesu-ft-891-review/ As for myself, I bought it mainly to be an SSB mountaintop and office rig. I try to operate around 40w, to conserve battery. Local friends have not noticed any noise issues with my signal, and now that I have EQ'd the typical Yaesu MH-31b for DX, I am getting great reports. I don't think this would be my rig, if I were a digital modes person (which I am not). There are far better choices. In any case, it seems my digital modes friends are typically running at far less than even 50w (more like 5 to 10w). Absolutely zero noise issues to worry about, at those levels -- nada. Even in very close proximity.
