Hello Roger,
You are right about the transformer thing and
the calculation being incorrect, however, you will be pleased to know this has
been put right in the second edition.
I totally agree, these books are an excellent
starting point.

Mike (et al),
As an owner of the 1st edition of LF Today
may I thank you for this most helpful little book; there has been much in it
that I've enjoyed and used as sources of information. I do hope a new version
is produced in due course.
Maybe the next edition will include
something about WSPR and how effective results may be achieved, on 500kHz at
least, with a totally simple station set-up like my own running just
microwatts ERP.
The only error/confusion I spotted is on p81 (of the
1st edition) when it talks about current transformers. There is something
screwy here when working out the current in the secondary.
