Written by David, KK4CQD

Dave, KI4PSR gave the Technical talk at the February Monthly Meeting with the first in a series of presentations on antenna tuners.

In this first installment Dave covered the basics of antenna tuners and dispelled some myths (a tuner does not improve the radiation efficieny of the antenna.) An overview of reactance concepts, reactive matching and an introduction to L-network tuner configurations were next followed up with a brief demonstration.

Dave says this presentation was inspired by the work of Davide, IZ2UUF

and provided a link to one of IZ2UUF’s youtube videos on tuner losses:

Winlink – Distinguished Patriot Medal to WCARES members

Posted on January 27, 2020 at 22:07.

Written by David, KK4CQD

As those of you who attended the recent WCARES Monthly Meeting heard, WCARES members Steve K4CJX and Phil W4PHS received the Military Department of Tennessee Adjutant General’s Distinguished Patriot Medal for their “distinguished patriotic service”.

WCARES EC Ed Hudgens, WB4RHQ congratulates Steve and Phil.

From the ARRL news link: http://www.arrl.org/news/winlink-development-team-members-awarded-tennessee-military-department-patriot-medals:

Steve Waterman, K4CJX, was awarded “for his distinguished patriotic service as the Winlink Network Administrator,” citing his “vision, hard work, and dedication to emergency communication [that] contributed significantly to the disaster readiness and communications interoperability of the emergency responders across the United States and the world.”

Phil Sherrod, W4PHS, was awarded the medal “for his distinguished patriotic service as the lead developer for Winlink,” with “technical skill, hard work, and dedication to emergency communication [that] contributed significantly to the disaster readiness and communications interoperability of the emergency responders across the United States and the world.”

Packet Winlink with a TinyTrak4

Written by David, KK4CQD

Jeff, WB5WAJ was looking into uses for his TinyTrak4 and came across this article by N3LUD describing how to use it with Winlink Express. Jeff has successfully used this setup for Packet Winlink with his Yaesu 7800 and says “The install is very straight forward. The radio has a 6 pin data jack. The cable connects to the radio and then to the TinyTrak4. This cable can be bought from Byonics. Then there is a USB cable from the TinyTrak4 to the computer.”

http://n3lud.blogspot.com/2013/10/tinytrak-4-and-winlink-rms-express.html

It is also worth noting that you don’t need a radio with a dedicated data port and can often make the connections to the mic and speaker/headphone jacks of a basic mobile radio or HT. Make your own cable using the information in your radio’s user or service manual or purchase one from a company like Byonics: cable selection chart.

For an overview of Packet, VA3ROM has a presentation on VHF Packet which covers scenarios, equipment and examples such as Winlink:

Winlink is an important capability for WCARES members so if you don’t yet have a Winlink Packet solution, try this out.

VARA is available for HF as well as FM and can be loaded and used from within Winlink Express. Select Vara Winlink or Vara FM Winlink from the Open Session: menu in Winlink Express and follow the instructions in install it.

VARA is shareware; paying the shareware fee unlocks it’s full speed.
