Added another re-editted past TCA column "How do you solve a 'problem' like FT8?" to the All Things
Digital page & this completes all previously puublished 2018 columns.
August 11, 2019
Finally had some time to re-edit
& release a set of my past TCA columns: "The Pixie 2", parts 1 and 2 & "The Cricket". See the All Things Digital page.
added two new links to NASA's INSPIRE
project & the SARA
websites to my All Things Digital
page. Both have interesting
ionopshere studies using VLF (very low frequency) receivers for students of all ages. One is designed for portable
field work & the other for fixed use with a computer.

Added a simple & inexpensive 80 m band quarter-wave wire
sloper down to the bottom of my base loaded homemade vertical. The high end is only 6 m AGL with two (shared with the
vertical) 15 m slightly elevated radials running north to south in line with & under the sloper. It has performed
very well in all directions using FT8 & even picked up a few DX stations. Slopers are a great alternative if you don't have
room for full-sized dipoles, and it even improved the VSWR for the vertical antenna a tad.
Added support files
for my latest TCA ATD040 column "JS8 Calling: Part 2" to the All Things Digital page.

Added an interesting
paper called "A Citzen Science Network for Measurements of Atmospheric Ionizaing Radiation Levels" to the All Things Digital page.
During periods of solar minima old Sol isn't as effective in "shooing" away any incoming highly energized galactic cosmic rays
from penetrating deeper down through the Earth's magnetosphere & reaching closer to the surface. People living at high altitudes,
frequency high flyers, and those living in specific parts of the world are irradiate with higher levels of radiation. Its also believed
that weather & climate can be affected during prolonged periods of solar minimas as a result of intense cosmic ray irradiation
of the upper atomosphere (stratosphere).

Added support files for my latest TCA ATD039 column called "JS8 Calling:
Part 1" to the All Things Digital Page page.
April 7 2019
Added new link (midway down this page) to Hamwaves
which has some excellent propagation information at a glance & other useful tools & links.
30 March 2019
Added new link
(midway down this page) to Dr. Tamitha Skov's Space Weather Woman
solar forecast website. She makes the science very easy
to understand for those of use without doctorates in astrophysics!
The rapid & amazing development of JS8Call
Jordan, KN4CRD has plans for a separate JS8Call database webserver similar to the WSPRNet with added messaging & propagation features.
Added support files for my latest ATD038 column called "Amateur Radio Science 102" to the All Things
31 January 2019
Finally got around to installing & trying the newest digital data mode JS8Call by Jordan
Sherer, KN4CRD. I must say that it's quite a change from the rather frantic or hectic paced FT8 computer-to-computer "contacts"of
basic station data, as compared to conversing with another person. The novelty of FT8 wore off quickly for me so it's nice to have
a new digital data weak-signal mode that combines aspects of packet radio, APRS, FT8 & say Olivia for keyboarding. Well done,
26 January 2019
Added newly revised column articles & their support files for ATD030, ATD031 ("The Effect of Edison
- parts 1 & 2, & ATD032 "The Great American Solar Eclipse" to the All Things Digital page. I left ATD032 in its originally
published TCA form becase the article & layout turned out so well that I can't improve upon it.
12 December 2018
support files for my latest ATD037 column called Amateur Radio Science 101 to the All Things Digital page.
version 2 release of WSJT-X software is online (as of 10 Dec) & all users are requested to immediately update any older versions
of the program because of the significant changes made to it rendering older versions incompatible for some data modes (FT8
I received a very nice email from Andrea & her daughter Skylar. Skylar is very interested in Amateur Radio &
has been using information from my website. Skylar sent me this link as a "thank you" link: Telecommunications Timeline.
new link on this page to the awesome SpaceWeatherLive solar and aurora information website. It has both real-time solar/aurora
and archived historical data of the same.
