[Elecraft] Upgrading a K3?

Eric.

Firstly, you absolutely MUST use an anti-static mat, suitably connected to 
ground and an anti-static wrist strap. Whilst you might "get away with it" 
without those items, you may cause unseen damage and you won't know until it 
breaks down. I know the manuals state that you can "touch a metal object", 
but that's very hit and miss.

I upgraded a pair of K3s earlier this year and I used a combination of 
guesswork and observation. Most of the mods and upgrades come with 
sufficient instructions to tell you what you are replacing, so that you can 
look and see if it's already been done. If you know the pedigree of the K3, 
you may be able to guess by the mfr date of the K3 and the date the mod was 
issued. Otherwise, just remove all covers and take a good look at each 
component to be replaced/added. All mod instructions are available from 
Elecraft as downloads, so you can check before you order parts.

SMD capability is useful but not essential, although you will need an ESD 
safe soldering iron with a fine tip and probably a good magnifying glass.

I can send you a list of all the mods and upgrades I performed, if you care 
to send me a pm.

I've just pick up a bare-bones circa 2010 K3/100



I have a couple of questions regarding upgrading it.

How can I tell if the mods (as opposed to upgrades) have been done?



In addition to adding filters, I'll be installing a KSYN3A, and K-Pod (power
mod for the K3).



How hard is it to install the upgrades, and do I need the anti-static mat,
wrist strap et al to do them (I don't have them).



Thanks & 73,
