A good thing about SDR radios is that it can always be upgraded by simply upgrading software only.
I'm still not crazy about them because of noisy receivers. My KX3 is the same way, it's receiver is a bit too noisy for my liking.

Would you explain this statement, please? The KX3 is
ranked in the top 10 for receiver performance by Rob Sherwood. "Noisy" in what way? Compared to what?
One of the things that has really thrown a lot of people is the new trend towards accurate S-meters in modern radios, particularly the direct sampling SDRs, that are not built by the Big Three. For a very long time now, Yaesu, Icom and Kenwood have had the marketing department make the engineering department design S-metering that is horribly non-linear, such that the difference between S-units is in the range of 3dB below S8 or so. This has the effect of making noise floors appear to be much lower than on a properly linear S-meter where each S-unit is 6dB. The big three then claim that they have "quiet" receivers. But it is all a big lie. Even the Icom 7300 continues this legacy, as will the 7610 no doubt. Meanwhile, when people move up to a Flex or an Apache radio, quite often the first thing they complain about is how the receiver is so "noisy" compared to their beloved FTDX-5000, or whatever. They complain on one of the Flex or Apache forums and have to be schooled on the truth: "Yes Virginia, you really do have an S7 noise floor at your QTH."
