Practically any electret mic element today is going to be good or even
great. Having come from the era of "cans", with the wire headband,
cloth covered cord, and thin metal diaphram, that you wore forward of
your ears to prevent hearing damage, I've come to the conclusion that
the only headphone thing that really matters today is comfort in long
sessions. My Yamaha CM-500 pretty much fits that requirement. Fully
over my ears and very effective at blocking external noises. It would
be perfect if I didn't have to wear glasses to see the radio and
computer screen.
During the WW SSB, casual monitoring with my K3/P3 showed many [actually
most] of the signals with most of the energy right up next to the
suppressed carrier [low audio freqs] where it contributes almost nothing
to communications clarity, but does contain most of the power. The
energy falls off rapidly higher in the audio spectrum.
Jim, K9YC, has published an article in the NCJ which you can also find
at http://k9yc.com/ContestAudio.pdf I don't operate phone very much,
but following his TXEQ recommendations, my TX spectrum is full in the
screen shots others have sent me and I get unsolicited "great audio"
comments on SSB. The TXEQ profile has a much larger effect on transmit
audio quality than the microphone choice. Those signals in the contest
that had a full energy spectrum were a LOT easier to understand.
Another K9YC tip for those of us who remember "peak the grid, dip the
plate" and are therefore becoming somewhat long in the tooth -- The
Elecraft RXEQ has a range of +/-16 dB in each of the segments. 16 dB of
high frequency boost is not really enough for me. But, if I think of
the range as 0-32 dB, I get enough high boost to make SSB
understandable. I have to run the AF Gain higher, but it has plenty of
range.

I’ve read a lot of comments about Heil and the Yamaha boomset. Nobody has yet
suggested RadioSport boomsets (Arlan Communications,
http://www.arlancommunications.com/products/amateurradio/radiosport/rs60cf.asp).
I have several pairs. Although definitely on the high end of the market, they
are superbly built and extremely comfortable, with both dynamic and electret
condenser mic options. Some complain they’re too heavy, but I find them to be
great for me.

Dear Folks:
Although I'm primarily a CW op, and dabble in FT8 (sadly, sometimes there's no
one on anywhere else except for FT8), I'm thinking about expanding my SSB
presence on the bands. I have a K3s and would be interested if anyone has a
specific recommendation for a good microphone? I'm thinking about one of the
Heil microphones (either the Heil Gold or the Heil HM-10XD) but am willing to
look at anything else someone may recommend.
Thanks and 73 de Bernie, KF0QS
