[Elecraft] Audio question K-2

[Martin Storli - LA8OKA]

Hi Tim. My K2 had a very bad audio on transmitt until I did the modifications listed in KI6WX John's document named "Improving the Performance of the KSB2"http://folk.uio.no/sverre/LA3ZA/blog/K2/KI6WX/modifications_to_the_ksb2.pdfhttp://www.qrpproject.de/Media/pdf/SSBModsUK.pdfSome of the modifications listen has been included by Elecraft. The "Crystal Filter Bandwidth Modification" was not necessary to do on my K2.The "Improved 2nd Xtal Filter Flatness Modification" was not necessary to do on my K2.I did the "KSB2 Increased Gain Modification" as described. Please see below, it may make your K2 "wild".I did the "KSB2 Reduced Intermodulation Distortion Modification", this one seems to make wonders for the TX audio.The "PSK31 KSB2 ALC Time Constant Change" was not necessary to do on my K2.  Before these modifications I already had replaced R9 with a 15 kohm resistor and inserted a 1 kohm resistor on the basis of Q1 on the KSB-module to be able to control the output power of my K2 when used with the KPA100.http://elecraft.365791.n2.nabble.com/K2-ALC-and-power-control-on-40m-SSB-in-K2-100-td5719064.html After I did the KI6WX modifications the power control problem returned, this was solved with replacing the R98 with a 1kohm resistor.http://www.elecraft.com/Apps/Power_Control_Mod.htmlhttp://mailman.qth.net/pipermail/elecraft/2003-June/020096.html Now I have a good sounding K2 and I'm able to fully control the output power.

 Emne: [Elecraft] Audio question K-2
   

I have a k2 and the original elecraft mic. I want to use it on 75 meters and rag chew a little during the winter months. 

Where should the mic setting and compression setting be to produce audio that is pleasant to listen too...

I'm not interested at all in sounding like a broadcaster or trying to tailor my audio to every individuals liking.

But- I do get told often that it sounds a little "pinched" up.

I do run my k2/100 into an amp.

Any help is appreciated
