K2: T6 bifilar winding

lstavenhagen
Hi all,

Quick question about the bifilar windings on the bifilar transformers like T6. How critical is the twist in the two wires? When I did T6, I was unable to get a terribly consistent winding of the two wires together. Build manual says they should cross over about every 1/2", but some parts of the wires ended up a little tighter than that, others less. On some of the windings when I wound the core, they more or less didn't pass over each other at all for one or two windings (tho they were adjacent).

I'm assuming this is probably not super critical, but just curious.

I'm almost at the second part where you fire it up on 40 meters. If not this evening probably tomorrow evening I'll be there.....

LS,

The twisting is to keep the wires in close proximity to one another, so
it the twist is not critical.
