Just completed building my K2 Serial #05622 with NB and SSB options
installed it went together smoothly, the problems was some distortion caused
by the built in speaker. Bending the frame slightly solved the problem for
now. Just received a replacement speaker thanks to Elecraft customer service
and will replace the speaker if it acts up.

Wired up a cheap 600 Ohm dynamic CB microphone that I picked up at the
Sussex NJ hamfest and  found that it has good audio and plenty of punch with
the compressor set to 2::1.

Bob, my old S/N 1289 (2000 vintage) had a bent speaker frame. That happens
in shipment, apparently, because the metal of the frame is too soft for the
weight of the big magnet on it when the box it's in is banged very hard.
After straightening mine back then it's been FB. 

Be sure to check your SSB output on 10 meters. That's the band where the
audio level from the mic is the most critical. Mics that easily produce full
output on 40 meters often can't make anywhere near full output on 10. That's
because the overall transmitter gain is lower on the higher bands, requiring
more audio from the mic to make full power.
