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, and it's nice to have a new
digital data weak-signal mode that combines aspects of packet radio, APRS, FT8, and say Olivia for keyboarding. Well done, Jordan!
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 publishedTCA form becase the article and layout turned out so well that I can't improve upon it.

Added support files
for my latest ATD037 column on Amateur Radio "citizen" science 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).
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.

Reactivated my old ISS APRS
satellite gateway station using UISS and SatGate
add-on module. As a result of this, I've shutdown my NOAA APT satellite weather
map server system.
01 October 2018
Added support 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".
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 minima.

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.

MyKiwiSDR is on the SDR.hu server & it wasn't as hard as I thought it would be. Look or search for "VA3ROM" near
bottom of the ever growing receiver list.
Got a new IC-7300
yesterday & 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!.

lastest KiwiSDR firmware update from John Seamons, KF6VO, has taken this receiver to new heights of flight for an inexpensive direct
radio frequency sampling (DRFS) radio. We can now have up to eight separate 14-bit receivers because of its amazing field
programmable gate array (FPGA).
28 July 2018
is just a little over 1 year old & is dominating all other Amateur
Radio data modes, but its design team keeps right on tweaking the mode. An enhanced version will push its weak-signal decoding
level even deeper into the noise will be released in the early 2019.
