[Elecraft] K2: Audio hiss in headphones w/ KDSP2...

[Steve Kallal]

Thanks to all those who help with the the hiss problem. I was able to 
find a comment in the original thread by WA8SRA. Dale's solution is at 
http://mailman.qth.net/pipermail/elecraft/2003-October/024744.html. 
However I found a reply to Dale at

that mentions success doing the AF-Gain-Control Mod instead. My K2 is 
dated, sn 2289. All the new K2s already have this mod.

I did the mod. It took me about 2 hours and is well worth the effort. I 
am amazed at the quality of audio in my headphones. I don't feel the 
need to do the WA8SRA, at least not right away. The soft audio hiss only 
appears in my headphones when the volume is at 3/4 max now, rather than 
at min as before. It feels like a whole new K2.

I had long suspected something wasn't quite right with my K2. That is 
the problem w/ buying an older K2 as I did a year ago.

Thanks to all those who helped!
