[Elecraft] Hint on the K3 from W0CZ

[Kenneth A. Christiansen]

Last week end my XYL was gone and I got to spend some quality time with 
my K3.
I went out to Best Buy with my birthday gift certificate looking for a 
headset.
Most of their headsets needed to plug into a USB port on a computer so I 
had to
overlook them. I found a Dynex stereo headset for about $20.00 that 
looked as
though it might do the job. The salesman said I could bring it back if 
it didn't work.
The padded ear pieces are comfortable and the sound quality is good although
there is not much attenuation of external noise. I find that I can use 
them for hours
and my ears do not hurt.

The microphone seemed to have a lot of noise and hum on it and I thought 
maybe
it had a bad shield. It had been well packaged though so I decided to 
check into
it before I took it back. The microphone turned out to be connected with one
side to the SLEEVE of the plug and the other side to both the TIP and 
the RING.
I made an adapter cord with a stereo jack on one end and a mono plug on the
other end and my microphone problem went away.

The bottom line is  make or buy a stereo to mono adapter to use the 
microphone
part of a stereo headset on the K3.

73 for  now.
