[Icom] External Audio Filter

[doc]

A side-by-side comparison, thanks!

I operate primarily SSB and will also be running some digital  modes
soon.  Have lost all the 20wpm I learned to earn my Extra and am
one of those who never caught the CW fever.

Sounds as through the ClearSpeech may get it done ... and save
weight and space ... anyone want to buy a Timewave 599zx?  :-)

It is a shame that the CS doesn't allow the heterodyne-killer
circuitry to be toggled in and out.  Mod anyone?

Thanks! & 73, doc KD4E
