You want a dissipative surface not a highly conductive one.

Here is the link.  The shipping brings it us to the $16 level.  You will need to buy a wrist strap with a 1meg resistor to complete the work station.

Many thanks to all who have responded to my Antistatic problem with the K3S Kit.  I finally found a 12"X22" mat on Ebay for $16 that has electrical specifications that fit the bill for a true antistatic surface.  I can easily handle all the static sensitive boards in the K3S.  During my work career I have seen two many cross section, where ESD obliterated an otherwise good device, to fail and be sure not to inadvertently damage the radio my wife agreed that I could purchase.

All of your ideas have helped me and I possibly could have handled things without the ESD Mat.

I have built a “number” of Elecraft kits and never once did I use an anti-static mat or wrist ground strap.

 

Just let common sense prevail and place your work on a non-static surface such as a wooden desk or work bench etc.

 

Before you touch anything else, sit down and touch something you know to be ground for a second.

 

Do this “touch” thing often as you work while NOT touching any boards or parts, and especially before you un-wrap anything sensitive.

 

Don’t shuffle around or get up unless you repeat the sequence above.

The anti-static mat should not just be any old rubber. It has to be
conductive in order to dissipate the static. But not TOO conductive:
otherwise it would be a safety hazard and/or allow sparking. There are
ANSI specs for how conductive the mat should be. Beware: some mats
don't even come close to meeting spec and are almost useless for
preventing static discharge. See my previous posting for recommendations:

http://www.mail-archive.com/elecraft%40mailman.qth.net/msg94407.html

The wrist strap(s) should be connected to the anti-static mat. The goal
is to get your body at the same electrical potential as the equipment
you're working on so that no sparking can occur. And the mat should be
connected to the electrical system safety ground because the soldering
iron and test equipment are typically grounded and you want everything
to be at the same potential.

By the way, the wrist strap should be one made for the purpose. They
have a 1 megohm resistor in series to prevent electrical shock.

Subject: [Elecraft_K3] New User: Question about 400 filter

 

I am a KX3 owner and just recently purchased a second hand K3. I intend to scour the manual and get up to speed and this sophisticated radio, but in the meantime I wanted to ask the group a question about one of the installed roofing filters.


As I am checking out the functions of the radio (without antenna connected), and as I scroll through the filters with the "width" control something unusual happens. When the 400khz crystal kicks in on FL3, an audible tone is heard and interestingly, it sounds like the same pitch as the side tone. Hmm...


I know I'm just getting to know the radio, but this seems not right.


Thanks!

John,

No problem. 
I apologize for my attempt at humor.  I did however get every one of the parts needed for the kit,
All the tiny screws etc.  Elecraft does a great job at packaging all the parts.  
I did not use an antistatic mat, but I had a wrist strap and always made sure the wire from the wrist strap was connected to the chassis of the K3.
Not advisable to not use an antistatic mat but I figured I need to keep me and the K3 chassis at the same potential.
Not trying to endorse not using a mat but this is how I assembled my Elecraft kits.

Bob

Anti-static mats (was: Re: [Elecraft_K3] KS3 Kit)

Al N1AL
 

Be careful - not all anti-static mats are created equal. The Radio Shack portable anti-static mat (P/N 276-2370) in particular does not do what it is supposed to do, based on my testing:

http://www.mail-archive.com/elecraft%40mailman.qth.net/msg94407.html

The mats that work correctly cost a little more, but a cheap mat is no bargain if it doesn't work.
