[Elecraft] Low audio on K1 s/n 1253

Sun Jul 7 19:12:00 2002

Well I found the problem, it was the speaker.  I used a different one
and life is good again.  I would never had thought that a simple speaker
change would make that much difference in audio level, I can understand
how a cheap speaker can make it sound poor.  Seems that Elecraft should
look into a bit better speaker for the K-1.  This one sure leads one to
believe that there is something wrong with the audio stages.

Thanks to all those that pitched in and helped out here.

Steve:
You definitely have a problem in your K1 as there should be enough audio
to
be heard in a large nosie room at only the 12 Oclock position of the AF
Gain
control.  This is not the case with the K2's as they do have low audio.
I
would look for some problem like maybe you have the wires reversed on
the
speaker or a bad speaker.  Try connecting another speaker to your K1.
