KAT3 Toroids

I came home for lunch today and my KAT3 was in the mailbox. I opened
the box and the zip-lock bag and was looking at it through the
anti-static bag and noticed that two of the toroids nearest the
connector are not perpendicular with the circuit board. The photo shows
them perpendicular with the board, parallel with the other toroids.

Just perusing the KAT3 installation manual, I find nothing warning me
against adjusting the toroids as there is in the K3 assembly manual. Is
it safe to make the toroid straight or is it okay as it is?

Thanks,
Joel - W4JBB

Re: KAT3 Toroids

I would leave them alone. I don't think mine are 'straight' but it
works.

Do not be messing with toroids. They are NOT there to look pretty.

The manual may not specifically warn against all possible ill-advised
actions in your use of the product. There are millions of possible
ill-advised things you can do to screw up your product. DO what the manual
tells you to do and DON'T DO everything else. Stay to the script. That's
the one thing Elecraft is writing and updating as carefully as they can.
They put warnings in there when a lot of people are getting involved in the
same screwup. There is no genius anywhere that can correctly anticipate all
the strange things that customers will do.

Re: KAT3 Toroids

While I appreciate the concern about the warnings and what "not to do," I was not worried about cosmetics, but performance. I did not want that toroid coupling to something it wasn't supposed to couple to.

I have built several kits one of which I specifically remember having to move inductors away (by slightly bending) from a BNC chassis connector to prevent any stray coupling between the inductor and the connector.

If the toroid is fine at somewhat less than 90 degrees to the board, I am fine with it being there.

I *do* appreciate and respect the advice and comments.

Thanks,
Joel - W4JBB (very happy K3 owner)
