RADIO enthusiasts have been celebrating the 95th anniversary of the start
of Britain's first ever regular, advertised broadcast radio station, 2MT,
which came live from Writtle. The anniversary was recognised on Tuesday
February 14 February. To commemorate this anniversary and to celebrate the
pioneering young team of engineers, the Chelmsford Amateur Radio Society
transmitted from the same building where the original broadcasts commenced.
Members of Chelmsford Amateur Radio Society (CARS) regularly transmit to
fellow amateur radio hams from this historic hut and, for this celebration,
a team from CARS made contact with fellow amateurs on February 12 and
February 14. A special event call sign, GB95 2MT, was used to mark this
occasion.

Ride the Roller Coaster to Solar Minimum:

Most of us live on a 24-hour cycle beginning with waking up, going about
our jobs or other activities and then sleeping before waking up again. We
call it the circadian rhythm from the Latin circa dia or "about a day." The
sun has a rhythm too, called the 11-year solar cycle. During that time, we
see a rise in magnetic activity on the sun including sunspots (giant knots
of concentrated solar magnetism); titanic solar storms called flares; and
blasts of plasma -- clouds of electrons and protons -- billowing from our
star. The hubbub peaks and then gradually declines. Sunspot numbers plummet
as do the intensity and frequency of solar flares and phenomena like the
aurora borealis which is tied to solar activity.

Collegiate Amateur Radio Survey:

I'm doing an independent survey on college
ham radio clubs to help generate a list of
active clubs, clubs in need, and colleges
with no club but students with interest.
If you're a student, alumni, faculty, or
staff, please take a minute to add your
college club to the survey. Don't worry if
you think someone's done it already - that
shows me your club is even more active!
