It’s the faux indignation that is amusing. I’m fairly convinced that Yaesu have sufficient clue about their customers for such a radio, that this will sell enough. The suggestion it’s a facelift due to obsolete components etc. is reasonable. 817s must still be selling well enough that the costs in updating the model to this spec are justified such that the 818 replacement will sell.
I have no doubt Yaesu will have a variety of SDR internals in various stages of development and will roll out a fleet of new SDR based radios at some point. Most likely when the production and design costs of the current radios are suitable amortized and recovered.
