Eclipse" (RM065). See Radio Magic.
Reedited & posted the last two series of Snap Circuit articles "Part 3: Optical
Communications" (RM061) & "Part 4: The Snapino" (RM062). See Radio Magic.

With the launches of two more new
Russian digital weather satellites, both assigned to the same frequencies as the aging analog NOAA weather satellies on the 137
MHz band, there's just too much interference from the very wide band digital satellites so I've decided to end my NOAA satellite web
page after 20 years because there's no free decoding software that can do everything using the digital birds' telemetry
like the amazing WxToImg did for the analog birds.
The April 8 North American total solar eclipse will soon be here, but
the odds of having a clear sky view in my part of Ontario aren't in my favour, according to the climate records.
Fortunately, there're also
several more radio monitoring options available. Here's a list of new ones published in the recent ARRL Newsletter:
Solar Eclipse
QSO Party (SEQP)
Gladstone Signal Spotting Challenge
Medium Wave
Recording Event
Time Delay of Arrival (TDOA) Event
Grape
1 Doppler Receiver Project

Added support material for my next TCA (Feb-Mar 2024) column
"The Great American Annular Solar Eclipse" (RM063). See Radio Magic.
Speaking of solar eclipses, there's a total solar
eclipse coming up from Mexico through Texas, southern Ontario, Quebec, Maine & Canadian Maritimes on April 8. It will be the last
one in this decade crossing North America. The
HamSCI &
W8EDU ARC groups both have designed specific total solar eclipse
projects to study ionospheric effects it will have on radio frequencies & propagation. They're looking for hobby radio listeners
(no license or clear sky required) to signup then listen, collect & submit received data for analysis.

Reedited & posted two of my past published TCA articles: "Snap Circuits Part 1: Unleash Your Creativity!" & "Snap
Circuits Part 2: Mr. Morse" (RM059 & RM060). In part 2, I also include a short history of the development of the American
electromagnetic (or electric) telegraph & Morse code. See Radio Magic.

The amazing NOAA satellite flight engineers
have done it again! They have remotely fixed whatever was ailing the aging NOAA-15 back in October & it's once again
transmitting APT satellite weather images.
