OK, down to conversation with XYL about new rig . So does anybody have the answer to these? Can the antenna tuner be added by the owner at a later time? The DSP processor: What is the chip, or at least do we know if it is 16 bit or 32 bit? If 32 bit, 16 bit A/D converters? I’ve not yet found this in the manual. Thanks for the replies!
