Elecraft K4 first impression 

Haven't tried it yet. However, the keyboard is useful for searching for keywords in the manual. Since the manual are built in radio.

@@rk3td1 I have used mine to send CW from the K4. I wish the function keys to send when needed.

Bob, there is no obvious answer to this question. If you look at the price, I would prefer the 7610. However, I have a very long-standing love for the entire line of Elecraft radios. I'd still prefer the K4. And at the same time, I think TS890 is a very good radio.))
