[Elecraft] Muddy SSB

[Glenn Maclean]

Ron,
Thanks for your post. I too am having transmit audio problems. I posted a
message about it last week as you know. I am using the Elecraft MH2 Heil
microphone. I have done the SSB flattening mod. I used spectrogram and put
my K2 on 20 meters to adjust upper and lower side band filters on the OPT1
filter. My spectrogram adjustments look just like the samples that have been
posted on the Elecraft web site. The audio sounds terrible very constricted
and metallic or what ever you want to call it. I did the same thing you did
with an on the air QSO with John K7FD. I was able to improve the audio some
but it is not to my liking by any means yet. It is still constricted and
metallic sounding. My next move is to try a different microphone. I have had
my MH2 mic since Pacificon last fall. I have not tried  SSB with the MH2 mic
until this week. I am like you mostly a CW operator. I would like to use SSB
occasionally now that the Elecraft100 watt amp is out and the little HF
Packer amp http://www.hfprojects.com
I plan to get the Elecraft 100 watt amp in the near future. I have one of
the original SSB boards with the newer firmware prior to the amp firmware..

 Eric, Wayne or Gary  perhaps we can get some input from you guys on SSB
transmit audio improvements. I know that Ron and I are not the only ones
with crappy transmit audio. I know some K2's are sounding great.

Thanks in advance for any input from anyone.
