Just a quick followup in case it will be of use to somebody else some
day. I went with the TenTec 701 for my K2 because it was a quick and
easy option, and as Don said (thanks Don!), it "works well." Since
finishing K2 #6100 last week, I have made several 5-10w SSB contacts
from my QTH in North Georgia throughout the eastern US and Central
America, and the reports are that my audio is great! A 17m QRP contact
to Pennsylvania last night told me that "I was the smallest signal he
had worked that day, but the best sounding one"!!
Anyway, I am sure there are lots of great microphone options, but the
affordable little 701 "works well." I got the 8-pin connector from my
local RS store, and it was quite easy to wire the microphone and mic
header.

Greg,
The K2 needs a high output microphone, and that usually means an
electret type element. Most Icom mics (and Heil mics with the 'iC'
suffix) are the high output electret type. If you choose one of these
and wire your K2 configuration header for ICOM (with a 5.6k resistor
between the AF pin and the 5 volt pin), you should be able to just
plug it in.
The other electret mic that I know works well are those from TenTec -
the 701 is the hand mic. They come with a 4 pin mic connector that
you must change to 8 pins, but you can wire the new mic plug for any
mic configuration that you want - I suggest the Elecraft wiring -
straight across (use computer jumpers) on the mic header.

Hi all,
I am in the process of building K2 #6100 and need to start thinking
about a microphone. I've looked over the Reflector archives, and it
seems that there are lot of little mods needed for a variety of
microphones. The simplest solution would be a MH2, but I don't know
that I can wait until the June 15 production date. Question is, can
I not just jumper my K2 for Kenwood, buy a Heil HM-10 or Handi_Mic,
and plug-n-play (without any internal K2 mods)? I will get a Pro Set
someday, but I just want a decent little microphone to get me
started. Any suggestions?
Thanks and 73,
Greg
