[Elecraft] Long Felt Want

[Baker]

Here's a quick mod that I found improved my K2 receive audio.

The other weekend during JOTA I let a fellow club member operate=
 my 
K2 on CW.  As I use SSB exclusively  I was keen to see how it 
performed. It worked extremely  well and he was very impressed, 
however there was one area that I "felt" needed attention.

With  SSB I hardly advance the audio gain beyond 9 o'clock to get=
 a 
comfortable listening volume, but my friend was turning the gain=
 
right up to copy weak CW stations. This was fine until a strong 
signal came on and the whole top of my K2 started to vibrate !.

I had noticed that the audio seemed better with the KPA100=
 speaker 
when it was part of the K2 before I remoted it with the KAT100=
 ATU. 
This is because of a greater mass surrounding the speaker keeps=
 the 
vibration down.

To cut to the chase I used a piece of felt from a transport=
 blanket 
left over when we moved house. I cut this to fit around the=
 speaker 
and the KAT2  (I don't have the battery pack). This was then=
 glued 
with a general purpose adhesive to the bare metal inside the top=
 
cover.

End result I can now advance the audio gain way up, nothing=
 rattles 
and the sound quality is a lot rounder.

I would be interested in your comments if you try it.
