Re: [Elecraft] K3 #1140 For Sale on ebay

2008-09-10 Thread wrmoore


I see this went for about $125 MORE than it would have cost if bought from
Elecraft.  Interesting.  I guess that's one assessment of the premium on not
having to wait the 3.5-4 months!

[Elecraft] K3 Kenwood mic question

2008-08-13 Thread wrmoore

I have a Kenwood hand mic that I believe came with a TS-850SAT that I once
had.  It has no part number on it.  Just says Kenwood on the front and on
the back says Dynamic Microphone Impedance 600 ohms.  It has UP and DWN
buttons on top, and PTT.  It has served me well with my K2.  How would this
compare with the Elecraft MH2 mic?  Should I get the MH2 for the K3 or stick
with the Kenwood?  I'm only an occasional SSB op, so I'm not looking for
outstanding phone performance, just adequate.

Randy, KS4L
K2 #337
K3 on order!

Re: [Elecraft] K3 Transmit IMD (Mic adj for alc)

2008-08-06 Thread wrmoore


In light of the Sherwood presentation referenced in the thread about K3
audio, I haven't seen much comment on the spectrum analyzer plot of the K3
transmit IMD.  Is this still an artifact of the (now fixed) firmware error
mentioned by Eric earlier in this thread?

 The K3 firmware used for the original QST review did
 not turn off the
 K3's RF speech compressor clipper even when the
 compressor was set to
 zero for their TX IMD two tone test. This resulted
 in a significant
 increase in measured TX IMD when using an external 2
 tone source. We
 corrected this in a firmware update last month.

Or is this a currently existing situation with the K3?  I'm so from an
expert on these things that I hesitate to even ask, but it sounds like
Sherwood is saying the K3 is a bad neighbor in transmit IMD, and it looks
like it from the plots he provides.
