It is of some note that (except for a niggle here or there including the elimination of all possible noise — good luck with that) there hasn’t been much said about basic performance of the radio. That’s for good reason.
I would like to see a feature that would eliminate all “shouting at the K3” anytime one’s attached Windows-something computer running 15 ham radio apps gets confused and can’t talk to the radio or screws something up :-) Most of the feature requests seem to be related to contesting or remote operation or the furthering of the evolutionary enhancement of the index finger — but not being a gamer myself, I’m perfectly happy with a radio being just a … ah … um … compact, lightweight, transportable (and portable) high performance radio. Bogged down into a larger and heavier box? — not so much. I replaced several of those larger, heavier, and perfectly adequate boxes with a K3 for a reason. It would be hard to go back. Now, all that might change if the new one was truly “spectacular” and made the K3 look like a DX-20 by comparison — the right radio could be better than food on the table :-). And I do like the EER idea. Grant NQ5T K3 #2091 KX3 #8342 > On Mar 25, 2019, at 2:35 PM, W2xj <[email protected]> wrote: > > I’ve read a lot of interesting ideas relating mostly to features.
