[Elecraft] Effective add-on for your K1 or K2

Thu Mar 27 10:07:01 2003

Hi folks -
Another unit that I think works fairly well is the Clearspeech base unit (not the speaker unit). It's relatively small and seems to have a good algorithm - however, its primary benefit is on SSB - does not work so well on cw.
 I have a huge amount of respect for Idiom Press's Logikey as well as his service  -  great folks. On that alone I will order the SCAF filter just to see how it does. The old Index Labs QRP+ used a SCAF - it was interesting, but very hard to tell it's usefulness when it's on a rig like the QRP+.
