Winlink – Distinguished Patriot Medal to WCARES members

Written by

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

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.”

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.

SKYWARN RECOGNITION DAY OPERATOR REGISTRATION NOW AVAILABLE!

SKYWARN Recognition Day was created in 1999 by the National Weather Service
and the American Radio Relay League. Amateur radio operators comprise a
large percentage of SKYWARN volunteers across the country, providing vital
communication between the NWS and emergency management if normal
communications become inoperative. During this special event operators
working from NWS offices contact other radio operators across the world.

Where & When:
NWS Nashville Forecast Office,
500 Weather Station Road,
Old Hickory, TN

December 7th, from 0000 – 2400 UTC (Local time: 6 PM Friday 12/6 to 6 PM Saturday 12/7) (calendar)

This is a relaxed event with an easy exchange (call sign, signal report,
location and brief local weather description). We’ll have two HF stations
and one VHF/UHF station. Modes will be SSB and FM. Operating/logging time
slots are in 2 hour segments; N4CLO Laura will work out any scheduling
issues with those registering.

VARA, a presentation by Tim, AD4CJ

Written by

In addition to accepting the award for their 2018 November Sweepstakes win, Tim, AD4CJ gave a presentation on VARA. VARA is a software modem using orthogonal frequency-division multiplexing (OFDM) modulation.

VARA is capable of HF speeds comparable with Pactor 3. It does this using 52 carriers limited to 42 bps thus satisfying the FCC symbol rate requirements of 300 baud or less for any carrier. VARA uses a bandwidth of 2400 Hz.

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.

For more information or to download VARA for HF, FM as well as the documentation etc. visit https://rosmodem.wordpress.com .

Morse Code Tutor Build Event 1

Written by

This past Saturday saw a number of WCARES members take part in the first of two Morse Code Tutor build sessions coordinated by Dave, KI4PSR and Cliff, N4CCB. Dave put together a very nice kit of parts which included an update of the W8BH version of the W8TEE Morse Code Tutor adding a very nice printed circuit board and 3D-printed case. Some members soldered their kits while others assembled boards Dave had pre-soldered, wired and tested!

For those that have signed up, the second build session will be this coming Saturday, Sept. 21st at the EOC.

Pictures from the first session are included below.
