[Elecraft] K3 using Clear Speech Speaker

[Keith Heimbold]

I do wish the K3 NR was better but for all the negatives I do use it on 40 & 80 with some success on 7-1 and 7-2.  It is not totally useless for me. It would be the one thing I would like Elecraft to improve if it was possible.

I absolutely love the K3 APF for weak signal CW work especially on 6m. Without it I would have not worked JA on 6m this past SSSP season.

I use notch sparingly but it does work ok for me on SSB as noted below.

Filtering...well it is extra special in that department and probably a major reason we own K3s.
