[Elecraft] KX2 speaker/headphone question

[stan levandowski]

Ken, "...two of the original speakers..." means you built them or Bill 
built them for you or you mean the "original" Sky-Tec?  I've tried it 
with the KX2 filter set all the way to 2.8.  Also tried it with my KX1 
and the same low volume.  


I don't understand this term "padding" but it was suggested to me in a 
post on the CW list that "most modern transceiver have headset outputs 
that are padded to protect hearing" and I thought that might have 
something to do with this low volume.


I really want to experience this phenomenal sound I've heard so much 
about!!!

In answer to a list member question ... the speaker is acoustically 
resonant and -very- narrow.  

I suspect Stan's build and his KX2's filtered output tone are too far 
apart.


I have two of the original speakers and they are phenomenal!

No,Peter, it "acts" like a filter to focus on CW frequencies between 
approx 500 to 700 Hz while downplaying higher frequency noise.  Good 
stuff available via Google and Youtube and page 43 of current QST

G'day,



CW resonant speaker ? - does it have a filter in it ?



If the frequency is significantly different to the KX2's filter it would 
explain the extremely low volume.

Hi folks.  I need some assistance.  Is the KX2's headset jack "padded" 
to protect hearing?



I'm asking because I built the "CW Resonant Speaker" in the current QST 
and it works great but the volume is so low that  it's unusable.





Do I have to take the speaker output directly off the KX2's speaker 
terminals to get more volume?





Thanks and 73,

Sorry for the bum post; fat fingers!!
