Voices from the ARRL Teachers Institute on Wireless Technology

ARRL Teachers Institute on Wireless Technology
[http://www.arrl.org/ti]


The ARRL Teachers Institute on Wireless Technology continues to bring
educators from around the country to ARRL Headquarters in Newington,
Connecticut, to learn how to engage students with amateur radio and radio
technology. The program helps tie wireless technology into science,
technology, engineering, and mathematics (STEM) education.

 
In their Own Words
This week, TI1, or the initial course of three, is being held. We're hearing
from teachers in their own words about the experience.

 
Jackie Blumer, KC9LEH, is the Earth/Space Science teacher at Greenville Jr.
High in Illinois. She's very active in aerospace and STEM teacher
development. This is what she wrote about her experience.


Here's what I'm up to...
�-�Creating circuits with breadboards: Delving into the fundamentals of
electronics by building circuits from scratch. This hands �-" on experience
is perfect for understanding how different components interact and work
together to create functioning devices.

�-�Becoming more proficient with soldering �-" Honing my soldering skills to
ensure precise and reliable connections. Soldering is an essential technique
for any budding engineer or electronics enthusiast, and I can't wait to
master it!

�-�Working on getting my General license �-" Advancing my knowledge and
capabilities in ham radio by aiming for my General license. This will not
only enhance my personal expertise but also enable me to bring more advanced
concepts to my students.

�-�I'm excited to bring this hands-on knowledge and experience back to my
students. Integrating these skills into my curriculum will provide them with
a deeper understanding of electronics and inspire them to pursue their own
STEM passions.

The Last Frontier: Alaska in the Log
Hams know how hard it can be to get Alaska on certain bands. So, too, has it
been challenging to get a teacher from Alaska to attend one of the Teachers
Institute cohorts. It is a tradition for each educator to put a pin in the
map for where they're from, and this week - a pin went into Alaska for the
first time. Dana Serfass teaches at Gruening Middle School in Eagle River,
Alaska.

Get On the Air during VHF Contest Season

VHF contesting season is in full swing! Summer weather brings with it
enhanced propagation. With good conditions, stations hundreds of miles away
can be worked via tropospheric ducting, E-skip, and perhaps even meteor
scatter. If you have an HF rig that includes 6 meters or VHF/UHF capability,
you've got just the tools you need to take advantage of these enhancements!
US amateurs of all license classes may participate in these events, so they
are a great way for Technician-class hams to compete in contests.

 
There are several upcoming VHF+ contests coming up. The 2024 CQ World Wide
VHF Contest [ https://cqww-vhf.com/ ] is this weekend, beginning at 1800 UTC
on Saturday, July 20 and concluding at 2100 UTC on Sunday, July 21.
Participants can operate on the 6- and 2- meter bands.

 
The first of the VHF Fall Sprints, the 6-meter Sprint, will be held from 1800
- 2200 UTC on Saturday, August 10. The sprints continue in September with
single-band events on 144, 222, and 432 MHz. The final sprint, held on
Saturday, October 5, includes all bands 902 MHz and above.

 
For rules, see www.packratvhf.com/index.php/fall-sprints [
https://www.packratvhf.com/index.php/fall-sprints ] .

 
Closing out the VHF contest season is the ARRL September VHF Contest [
http://www.arrl.org/september-vhf ] , which will be held from 1800 UTC on
Saturday, September 14 through 0259 UTC on Monday, September 16. All amateur
frequencies above 50 MHz may be used.

 
For activities on the higher VHF and UHF bands, there are two contest
opportunities coming up. The ARRL 222 and Up Distance Contest [
http://www.arrl.org/222-mhz-and-up-distance-contest ] begins at 1800 UTC on
Saturday, August 3 and concludes at 1759 UTC on Sunday, August 4. Operation
is allowed on all bands from 222 MHz through 241 GHz.

 
The ARRL 10 GHz and up Contest [ http://www.arrl.org/10-ghz-up ] will be held
the weekends of August 17 - 19 and September 21 - 23, from 0900 UTC Saturday
through 0759 UTC Monday. Any amateur band from 10 GHz through light may be
used.


ARRL Momobeam
[http://www.arrl.org/beam]


If you need an antenna for the VHF contest season, ARRL has a space- and
budget-conscious solution, with two antennas in one. The ARRL Dual-band
Momobeam 6/10 Antenna [ http://www.arrl.org/beam ] features a 10-meter Moxon
(28 MHz) and 6-meter Yagi (50 MHz). The antenna is made of aluminum tubes,
galvanized steel hardware, UV-resistant POM-C driver insulators, and
polypropylene clamps. Assembly is easy, and all tubes are labeled. It comes
with two sets of hardware �-" one for permanent install and the other for
portable use. The antenna retails for $299.95 and is available in the ARRL
Store [
https://home.arrl.org/action/Store/Product-Details/productId/2018039112 ] .
It is designed to get Techs active on 6 and 10 meters while Solar Cycle 25 is
near its peak.

HamCon:Zion 2024

HamCon: Zion 2024
[https://www.hamconzion.com/]


HamCon:Zion 2024 [ https://www.hamconzion.com/ ] , hosting the ARRL Rocky
Mountain Division Convention, the Young Ladies Radio League 85th Convention,
and the RV Radio Network's 2024 Western Rally, was a success. The inaugural
event, held in St. George, Utah, was well attended and many reported the
facility and events were first-rate.

 
ARRL National Educator Gordon West, WB6NOA, was in the ARRL booth greeting
visitors and gave a presentation. ARRL Treasurer John Sager, WJ7S, hosted the
ARRL forum at the event. "The vibe was definitely positive, and I think ARRL
was very well represented. Gordo was a rockstar! He had a crowd around him
everywhere he went," said Sager.


The HamCon:Zion Facebook page [ https://www.facebook.com/HamConZion ] has
several video updates from Ryan Seegmiller, W7RGS, shot during the event. A
brief power outage affecting much of the area caused the gathering to wind
down a few minutes prematurely. The event was organized by the Dixie Amateur
Radio Club (DARC) in St. George, an ARRL Affiliated Club. It was the group's
first large convention, but plans are already in the works for the next one.


Amateur Radio Participates in World's Largest Naval Exercise

Rim of the Pacific (RIMPAC) 2024
[https://www.cpf.navy.mil/RIMPAC/]


"Partners: Integrated and Prepared" is the theme for Rim of the Pacific
(RIMPAC) 2024 [ https://www.cpf.navy.mil/RIMPAC/ ] , the world's largest
international military maritime exercise, which began June 27, and will come
to a close on August 1. Conducted from Joint Base Pearl Harbor-Hickam in
Oahu, Hawaii, the exercise encompasses many islands in the Hawaiian chain.

 
The event included 29 nations, 40 surface ships, three submarines, 14
national land forces, more than 150 aircraft, and more than 25,000 personnel,
including amateur radio operators working with health care facilities.

 
The amateur radio portion of the exercise has been completed. ARRL Assistant
Section Manager and State Government Liaison Michael Miller, KH6ML, said 36
amateur radio operators from Hawaii volunteered to demonstrate the value of
amateur radio in emergency preparedness and response.

 
"It turned out very good," said Miller. "Some of hospitals, staff and
administrators involved had their first experience with amateur radio. The
operators were able to blend their skills using public service radios,
satellite phones, as well as amateur radio."

 
Miller pointed out that hospitals on the smaller islands don't usually have a
full-time communications officer, so working with amateur radio gives them
experience for future emergencies. The amateurs worked with Health Comm
Hawaii [ https://ham.aditl.com/hc/ ] which provides amateur radio
communications to health care associations in Hawaii during emergencies and
disasters.

 
"Health Comm Hawaii really needs 100 more operators for backup and to build
skill sets through monthly exercises," Miller added.

 
Vice Adm. John Wade, commander, U.S. 3rd Fleet and RIMPAC 2024 Combined Task
Force (CTF) commander, said the Rim of the Pacific exercise has grown over
the years to be the world's largest and premier joint maritime training
opportunity. "The exercise's purpose is to build relationships, to enhance
interoperability and proficiency, and, ultimately, contribute to the peace
and stability in the vitally important Indo-Pacific region."

 
Many of the volunteers participating in RIMPAC 2024 are also members of other
vital emergency communication groups, such as Amateur Radio Emergency
Service®(ARES®), Radio Amateur Civil Emergency Service (RACES), and
Community Emergency Response Team (CERT).

Thirty-two amateur radio operators from clubs across Central New York turned
out to help with communications for the Boilermaker Road Race in Utica, New
York on Sunday July 14, 2024. The event is known for bringing some of the
best runners in the world to upstate New York. A total of 14,000 participants
competed in three different categories: 5K, 15K, and a 15K wheelchair event.
Don Peterson, KD2ILO, president of the Fort Herkimer Amateur Radio
Association [ https://www.fhara.net/ ] , said his club brought its Disaster
Action Response Trailer (DART) to help state, county, and local police
agencies by being the extra eyes and ears that help keep the race running
smoothly. The trailer also helped increase awareness of amateur radio and its
importance to local events and emergency situations around the world.
