[Elecraft] KX3 Voice Monitor

[David Ahrendts]

Gents, before we stray on this thread. Appreciate all of your input, Genuinely. But, I never had an “issue of a delay” in response in the MON function. My issue was a “muddy” audio response, i.e.: not sibilant enough for my taste, rather weighty at the bottom audio freqs but not balanced at the top, etc. And I wasn’t sure, being three-weeks into the KX3 as a newby, that I was actually hearing what my microphone was producing. A nice 10-minute session of DVRing helped tremendously and I did come up with EQ that I prefer — to my ear: good presence, not muddy, pushed 2400 and 3200 gently. This is with the wonderful Heil MC5.1 Gold Elite which, I think already pushes the 2K mark some.  Gonna do the same test for the fabulous Elecraft MH3 another day. My conclusion: MON is pretty darn close, but there is nothing like DVRing it and stepping aside to really listen objectively while you’ree not speaking. Best to you all and 73s.
