[Elecraft] RE: Does anyone miss passband tuning, audio notch on K2?

[George, W5YR]

Thanks, Vic, for filling in some of my blanks.

I am probably just spoiled from too many years of operating the "big
iron" and have not yet learned how to make the most of the
capabilities of the K2.

Having to "work" at running a radio like the K2 can be a change of
pace from something like the Icom PRO2!   <:}

But I greatly enjoy operating both radios!
