That's correct. There are no partial turns on a toroid.

I, also, am very right handed. I wound the toroids without much thought
about the 'right way'. My K2 #4901 is running perfectly and checked out at
each alignment stage. Maybe I wound them 'correctly', but I don't really
think whether the lead comes over the top of the core or from under it
Hi Brent:
To add to what Vic said, make sure that you have the power calibration done
properly. Also, one of our British friends recently replaced the C80/C81
caps AND the R19 and R20 resistors with locally procurred 4700 pf and 1.5
Ohm 2W resistors and all of the problems went away. It is my

This adds another turn to the toroid, 1/2 a turn at each end..
No. You can't have half a turn on a toroid. It's only an extrsa turn if
it passes through the middle. You can do as you please with the ends.
If a toroid has been wound backwards, it is best to strip
If anyone has a Palomar Engineers M-840 surplus to their needs, please

Thanks.

When studying the HAM workbooks from ARRL, I found a few inconsistency in
statements, example one of many: Is there a reason why HAM's use 40 meters (or
other band) at 7.125 kHz (or other frequency) then say the antenna should be
34.5 feet
would it not be easier to keep everything in metric
Like it or not, the US is still using feet and yards, not centimeters
and meters. The shortwave bands have traditionally been specified using
the metric system. However, we don't typically have meter sticks
handy. So if the ARRL would say to use an antenna 10.52 meters long,
the first thing

specify it in feet to start with? It's inconsistent, but sometimes
handy to mix units.

I've been a technical and scientific writer since the early 1960's. In all
that time I've worked in metric right here in the USA. It's what most of the

They call it the 'English' system, but even the English folks now measure
things in the metric system - only we Americans are the holdouts to the more
convenient and sane metric system.
For myself, I have a good concept of how long a foot (or yard, or inch) is,

I recently completed the construction of K2 N4 4875 and it works very well!
Last year, I built K1 nr 1875 and I now realize that I wound ALL its toroids
with one turn too much!
But K1 works OK
Would I gain anything by correcting my mistake and rewinding the toroids
with the proper number of
Don,
As a lover and rebuilder of old cars, I find I have ASF, BSF,

Mixing units is not always benign.
September 1999: NASA lost a $125 million Mars orbiter because a
Lockheed Martin engineering team used English units of measurement
while the agency's team used the more conventional metric system for
a key spacecraft operation.
I would argue this
For myself, I have a good concept of how long a foot (or yard, or

centimeter even though I have worked with metric units in engineering
circles for over 30 years of my life.
Hmmm ... I think everyone's experience is different.

OK, I missed 4 and 20, but I was making a practical point, not a
mathematical one so I deliberately left 1 and 100 out!

Don, I don't think the metric system is sane!!! I have found out what 5 and
8 meters is when it comes to the length of antennas but I now have the
conversion bookmarked in favorites!!
