A Little Light Humor
Cafe visitors are amongst the most intelligent and most clever folks
on the World Wide Web. I receive many e-mails, and an occasional phone
call, from people in response to items I post on the website. Whenever
appropriate, I ask permission to use it for content, with an offer to
give full credit and attribution for the idea. I have been surprised
at how often the person prefers to keep the communications private,
which I always honor. That's too bad because, believe me, you have missed
out on some really good insider information over the years.
March 17, 2014 (St. Patrick's Day, don't 'ya know),
I posted a headline from the Amateur Radio Relay League website, "ARRL
to FCC: 'Grow Light' Ballast Causes HF Interference, Violates Rules."
The ARRL urged the FCC action to halt sales of the
Lumatek LK-1000 electronic ballast and to recall devices already
on store shelves or in the hands of consumers. "ARRL has received numerous
complaints from Amateur Radio operators of significant noise in the
medium and high frequency bands between 1.8 MHz and 30 MHz
from 'grow lights' and other RF lighting devices generally."
Upon seeing the headline, Mr. Harold Kravatsky wittily remarked
to me, "Look on the positive side. If a modulator is added to the ballast
it can be used as a community broadcasting station. The receivers don't
even have to be tuned. Any frequency will work." It is the essence of
ultrawideband (UWB) communications! Thanks, Harold!

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas
and reference material while performing my work as an RF system and circuit design engineer.
The Internet was still largely an unknown entity at the time and not much was available
in the form of WYSIWYG
