Every April 18th, radio amateurs worldwide take to the airwaves in
celebration of World Amateur Radio Day. It was on that
day in 1925 that the International Amateur Radio Union (IARU) was
formed. Today, Amateur Radio is more popular than ever, with over
3,000,000 licensed operators! World Amateur
Radio Day is the day when IARU Member-Societies can show our
capabilities to the public and enjoy global friendship with other
Apogee View is the name of the column that regularly
appears in the AMSAT Journal. It’s authored by Barry Baines,
WD4ASW the current President of the organization. AMSAT has just
recently started making this available on their Web site where even
non-members can stay up to date on the future direction of amateur radio
The printed version of CQ
Magazine has fallen behind the calendar by a few weeks causing some
subscribers to complain that they hadn’t yet received the March
edition of the publication. That question online confirmed that the
February edition was the last one sent. And then a few days later the
March edition began showing up. CQ Magazine’s struggles these last
few years has made some subscribers jumpy over delays in delivery. For
what it’s worth, the electronic
version seems to be consistently on time while the printed
version lags about six weeks behind.

Grounding and Bonding for the Radio
Amateur by Ward Silver, N0AX, is now available in
Kindle and paperback formats. The book shows you how to
make sure your station follows current standards for lightning
protection and communication systems, not to mention the National
New Kit from 4QSRP
Group - if your receiver is plagued with 60/120 cycle buzzing in your
shack or favorite portable QTH, the BUZZ-KILL will save
your sanity. From the creative mind of NMØS, the BUZZ-KILL is a special
audio filter that removes 60 cycle noise and all of its harmonics,
beating them down 40 db or more.

It’s a weak signal ham radio communication method facilitated by
the open source code that drives the project. There’s no doubt
that ham radio is better for the open source movement and the many
innovations made freely available to our community by it.
But it’s not all cupcakes and flowers. Sometimes, there are
those who “borrow” large portions of the code and rebrand it
as something new, which is actually okay, provided the obligations
assumed under the GNU General Public License (GPL) are respected.
And that brings us to a relatively new weak signal package called JTDX. But
before jumping on that bandwagon, you might want to read this message
from K1JT to its developer. It’s pointed, eye-opening stuff:
“While I have your attention, I must remind you of obligations
assumed under the GNU General Public License (GPL) when you copied the
source code of WSJT-X, made some changes, and renamed it as
”JTDX vXX.X … by UA3DJY".
“Compliance with GPL requires that a derivative work (such as
must be licensed in a compatible manner. Just saying ”It is open
software distributed under the GPL v3 license“ is not
“Apparently a significant fraction of JTDX distribution takes
the web site http://jt65-dx.com/download/wsjtx-ua3djy.html ”.
“I see nothing on that web site mentioning any license
“I see a JTDX screen shot in which the main window title is
”WSJT-X v1.7.0-devel JTDX v16.6 … by UA3DJY.“ We have
a program called ”WSJT-X v1.7.0-devel“, so I would not
expect to see
such a designation on a derivative work”.
“Describing JTDX as ”by UA3DJY“ is surely
misleading, and a violation
of the copyrights on our code. Probably more than 90% of code in your
work was written by someone other than yourself”.
“Finally: if you were truly committed to the Free Open Source
(FOSS) philosophy, I would expect your development work to be organized
in a way so that can give back to, as well as take from, the amateur
software development community. I can see no evidence that you are
doing this, for example with an open source-code repository”.
