The 5th of January it’s again Kids Day. This event is especially created to promote Amateur Radio to youth. This is a moment where you can share your amateur radio hobby with your family, grandkids, friends, scouts or even to the general public. This day can be the first time for youth to experience a real radio QSO, hopefully they get interested in becoming a licensed amateur radio operator.
You could make use of this suggested exchange: Name, age, location and favourite colour. Be sure to work the same station again if an operator has changed. To draw attention, call “CQ Kids Day.”
Suggested frequencies IARU R1:
10 Meters: 28.350 to 28.400 MHz
15 Meters: 21.360 to 21.400 MHz
20 Meters: 14.270 to 14.300 MHz

Peanut, the free amateur radio app for android devices that allowed many users to chat in virtual rooms linked to D-STAR, has been announced to stop.
It is not clear if the project has been suspended or if it has been permanently closed.
Latest updates from Jan 3, 2019 let us suppose it’s a temporary stop. Continue reading this article to get additional informations.
Screeshot of PA7LIM Page – Jan 1st 2019
Peanaut, written for hobby and for fun, by David Grootendorst PA7LIM has always been in development status, and it has never been released.
As per future reference here we include some details on this interesting project that has been recently stopped.
After having downloaded and executed Peanut for the first time, and having granted the use of Microphone, app gave immediately access to the application.
To connect the Peanut Server you needed to obtain a Code from the author itself.
Rooms available on Peanut were selectable as drop-down menu, and could be easily switched in real-time without the need to disconnect and reconnect the App client.
In addition to some language rooms, Peanut allowed you to connect to some of the D-Star reflectors.
Peanut server offered also a realtime dashboard with currently logged-in and last-seen users.
Peanut on Network Radios
Peanut runs on all Android 4.0 and higher devices and has been succesfully tested even on Inrico TM-7 and Senhaix N60 network radios.
Peanut app has never made available on Apple iPhone or iPad devices.
We consider Peanut an innovative project, apreciated by several hundreds of ham radio operators worldwide, and we really hope this project will find appropriate resources and conditions in orderr to be restarted. Thanks to PA7LIM David for such nice experience.
Update 3rd January 2019 : New version 1.43
David just uploaded new version 1.43.
You can upgrade simply accessing the Google Play Sotre, where maybe you already have an upgrade notification waiting for you.
This new version has some new features:
Name displayed along to the Call Sign
The possibility to hold the PTT to talk
An option to select audio output
It will work only when APP is in foreground
David is asking everyone to upgrade to latest version, and if stable, he will probably will keep the service up.
Screenshot – David_PA7LIM – january 3 2019
“When this version runs stable, I can keep the peanut project running and work on fixes when I have time. ”
This last sentence, let us suppose that the announced stop is going to be temporary.

Sort of similar to the one of the 6m omni. Instead of using twin-lead, this design makes use of a more or less regular double bazooka antenna (coaxial dipole). Your attention shall be drawn to the available standart literature, such as Rothammel. In order to “compute” the dimension, Karl Rothammel mentioned that the total length of the dipole shall be 95% of the free-space wavelength. The short-circuit bridges (closing the folded dipole) are to be placed at a distance-fraction being equal to the velocity factor of the coax cable used, which will be 66% using RG-58 or RG174.

WSJT-X 2.0 has been released on December 10, 2018, and the author, K1JT, in its release notes, states that this new version introduces important and radical enhancements to the FT8 and MSK144 modes that make those modes incompatible with older verisions.
The current General Availability (GA) release is WSJT-X 2.0.0
The FT8 and MSK144 protocols have been enhanced in a way that is not backward compatible with older program versions. The new protocols become the world-wide standards starting on December 10, 2018, and all users should upgrade to WSJT-X 2.0 by January 1, 2019. After that date, only the new FT8 and MSK144 should be used on the air.
