Added support files for my latest TCA ATD039 column called "JS8 Calling: Part 1" to the All
Things Digital 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
continues! Jordan, KN4CRD has plans for a separate
JS8Call database webserver similar to the WSPRNet with added messaging & propagation features.
23 February 2019
files for my latest ATD038 column called "Amateur Radio Science 102" to the All Things Digital page.
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, Jordan!
26 January 2019
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
Added support files for my latest
ATD037 column called Amateur Radio Science 101 to the All Things Digital page.
The 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 especially).
I received a very nice
email from Andrea & her daughter Skylar. Skylar has become very interested in Amateur Radio & has been using information
from my website. Skylar sent me this link as a "thank you" for using the ones on my website: Telecommunications Timeline. We
have been communicating with each other for a very, very long time. The basic message has always remained the same; only the medium
used to deliver it has changed over the millennia.
Added 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.

01 October 2018
files for my latest ATD036 column on FT8 to the All Things Digital page. Partly technical and commentary. Also added new
link near the bottom of this page for VE3EN's awesome SolarHam website.

WSJT-X has a slight problem that most users
don't know about. It seems that even though the default setting for saving *.wav audio files is set to "none", the program still merrily
writes them to the hard drive until it's full & "dies".
See my short article
about a semi-fix.
by KN4CRD is
a new program inspired by WSJT-X & other weak-signal programs. It has created much controversy because of the use the root name
but has no relationship to the original. But for better or for worse, FT8's phenomenal "overnight" success has rocked
the radio world to its core & this will lead to more imitation & innovaton as the solar cycle slowly winds its way to a 2020

If you own an older FlexRadio (1000 to 5000 models), check out the free KE9NS firmware upgrades
for these & software enhancements for PowerSDR. He also provides YouTube videos explaining how to operate your supercharged
Flex SDR using his enhancements.

My KiwiSDR is on the SDR.hu server & it wasn't as hard
as I thought it would be. Look or search for "VA3ROM" near the
bottom of the ever growing receiver list.
Got a new IC-7300
& am busy learning how to use it. It was easy enough to flash the firmware with the newest updates, then set it up for WSJT-X
& WSPR band hopping receive mode. All transceiver control & audio is via a single USB cable, plus it has a nice & large
& colourful data display with touch screen control. The deep discount sale price, free shipping & $100 USD Icom
rebate made it too much of a good deal to pass up!
