It Will be interesting to see more about this rig. The published specs are top drawer, but have not seen anything on the back panel connectivity (I/O). The specs (if confirmed by independent measurement) put it near the top of Sherwood's list, above the pure direct sampling SDR's as far as blocking is concerned, and really good 2KHz IMDR dynamic range. Reciprocal mixing is also quite good. If this holds, ergonomics and I/O operability are going to be the factors going forward in new rigs, as well as transmitter purity. This is better than the previous generation receivers in this price class, and marks a new standard as far as the above mentioned specs. I am waiting to hear of additional features beyond the receiver performance and the 3D band scope. My thought as others have said this may be a FTDX3000 replacement.
Currently own a IC 7300 which is very good for what it is. Not sure if this is an apples to apples comparison. The ICOM if properly set up has a very good 2D band scope. Its blocking performance is not as good due to it being direct sampling. This would only be a problem in very strong signal environments such as co located contest stations, and field day. The FTDX10 looks to be shooting for higher specs, mid tier in a portable package. This will make the TS590SG look long in the tooth.(also have a 590SG), which is also a very good rig. We are getting more bang for the buck with these new rigs. A fair comparison may be the K3S with only one RX, for RX performance, not sure on the features.
