[Elecraft] [K2] sanity check for winding T1 and T2 on KSB2 module
I'm nearing the end of my K2 build, and am working on the KSB2 module at the moment. On page 11 of the most recent version of the manual (Rev E), it shows the secondary winding going "against the grain" of the primary winding. I really want to start with wire 2 on the same side of the toroid as wire 3. The picture shows wire 2 on the same side as wire 4. This makes winding more difficult and doesn't allow for me to "go parallel" to the primary winding. http://www.elecraft.com/manual/KSB2%20manual%20rev%20E.pdf Is this just a bad schematic, or does it matter what side of the core 1-2 are, relative to 3-4? Same goes for T2, since it uses the same schematic. Thanks! -john W4PAH __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

John, The winding direction does not matter - just the turns ratio. So wind to so the green turns do not cross over the red winding and it will be neater and work just as well. 73, Don W3FPR On 9/16/2010 8:42 PM, John Shadle wrote: > I'm nearing the end of my K2 build, and am working on the KSB2 module > at the moment.

Thanks, Don. That's what I was guessing--but I wanted some "expert" opinions before I started tinning leads and soldering. -john W4PAH On Thu, Sep 16, 2010 at 9:00 PM, Don Wilhelm wrote: > John, > > The winding direction does not matter - just the turns ratio.
