This is a point of comparison I actually hadn’t considered.
I was apparently coming down with the flu as I was buying the radio on Wednesday, and by that evening I was quite sick. No, this isn’t a story I was telling my boss so I could stay home and play radio for the rest of the week – I haven’t been this sick in years. In any case, I spent a good bit of time with the KX2 in the last 72hrs. Got my first experience as a chaser too, but that’s another story.
I’ve never used a ft-817 so can’t compare it to that, but the KX3 is different than any other radio I’ve used. It really feels like the difference between a digital vs analog electronic device. The effect is hard to describe, but it shows up best when listening to cw. With a strong cw signal and a tight filter applied, the code sounds like it’s being generated by a computer. Voices sound different as well, more like (not surprisingly) listening to a station on websdr.org.
In general, I think the effect tends to make code more readable, which is good. Voices are just different, though sometimes I think my brain was getting better at sorting out faint voices from analog static so this is bit of a setback. It’s hard to as as all voices are faint right now. 40m noise floor was S9 all day yesterday.
Just another bit of info for someone who is trying to make this decision.
