Re: Elecraft Digest, Vol 12, Issue 38

I am surprised, and somewhat disillusioned to hear ‘questioning voices’  
along the lines of modifying the K2 radio design! I do believe there is even a  
portion of the company’s main page where they recommend the radio, just because
 SINCE YOU BUILT IT, you will be well acquainted to improve upon its  design!
 
Anyone that has ever designed any circuit device knows that there is always  
Revision A, Revision B, revision C etc. This is true of simple “DC” circuits,
 and is more likely with “AC” circuits. Besides, it has already come to the
fore  that there are certain design deficiencies! I don’t fault the
manufacturers for  this, its simply bound to happen!
 
So, fire up the soldering irons guys. Make your design modifications, and  
document them! That’s why you got a Ham license right, so as to get into the  
nitty gritty of electronics and radio  science?

Anyone else have any thoughts on my previous transverter post?

You Go, John!

Many of the improvements in the current K2's are just the result of
individuals deciding to make it "better", and they did. And for those mods
that didn't really pan out, they might not have been added to the production
design but you know a lot was learned trying and testing them.

Elecraft has a policy of supporting tinkerers!

I've been on the bands for over half a century, and I've yet to own a rig
for HF that I didn't build myself - from my own design, from something in a
construction article or from a kit. And the only VHF/UHF rigs I didn't build
are a couple of hand-helds I've owned over the years.

That's no everyone's "cup of tea" I understand, but for those with an itch
to tinker, never give up scratching it. Every rig I've ever owned, including
K2 S/N 1289 and KX1 S/N 0004 are works "in progress".

Keep a notebook. I have a ring binder for each rig. Take the time to put
your thoughts, copies of ideas from others, and the circuits and data from
any tests you have run or mods you try. It's what all engineers do,
professional and amateur. It gives you a running commentary of your flights
of fancy and your frustrations! Figuring out how to measure an "improvement"
of some sort is often the most challenging thing for those without an
electronics lab in their shop. But it can be done, and the sense of
achievement is in the doing of it.
