Brian,
I think Don, W3FPR, answered your question. FYI, My K2 and SSB is a fairly
early model from 2001. I did not like the bandwidth and changed it to 2.5khz
early on. I believe this was a mod from KI6XX. Don't have those notes handy.
Always got many unsolicited good audio reports for many
Thanks Don, Jim and George. I would guess that any method that shapes the
audio would have the same desired effect i.e. different mic element, equalizer,
etc.

Good question. I've never had any issues with my
audio reports, using the Elecraft MH2 mic; in fact
all audio reports have been positive. It sounds
like these mods are for the Proset K2 Heil
mic/headset (I'm not sure which Heil mic element
is in this model).
There were some K2 mods related
Phil:
Yeah my audio reports are fine with the MH2 as well. I'm not looking to widen
the K2 bandwidth.
Thanks
Brian

Those mods are not 'official Elecraft', but will help in reducing the
bass response of the KSB2. That is a good thing with any microphone
because the low frequency response just wastes power and does not add
much to communications quality.
It is applicable for any microphone, not just the

Nearly 10 years ago, I worked up some nice improvements to SSB TX that
added 6dB of gain to the mic circuit, which improved compression, and
tailored the frequency response to remove low end,
Thanks for posting this, Ray. I also was getting those kind of reports on my
K2. I was able to get the 1uF electrolytics but was unable to find the
0.1uF. G3RXQ was quick to respond to my email and said that a 0.1uF
monolithic could be used instead. The results are great, as confirmed by
hams I
George et al:
Did Elecraft ever adopt these (or any other) K2 SSB audio changes?

I use a Heil HC4 (DX) mike element in an upgraded hand mike.
I changed the mike gain with a resistor change as per mod.
I get very good audio reports - the mike has the 2K boost and the low
end cut... built in.
I never did the SSB filter upgrade and still running stock serial number
