Dan and others,

As soon as John's latest edition was distributed I started getting questions about that resistor. I informed John about the error but never saw any correction published. I have mentioned it several times here on the topband reflector, but it bears mentioning again.

The preamp schematic appears in many dozens of places on the internet. The only place you can be sure the info is correct is on my web page. The info is contained in the "Rotatable Flag" article. There is also some info about winding binocular core transformers, including photos.

Apparently I need to split the transformer and preamp info off into separate articles so that they can be "googled" easier.
