Hawaii Contest Station and Winlink Leveraged for 2019 Simulated Emergency Test:
ARES volunteers in Hawaii took the opportunity of the 2019 Simulated
Emergency Test (SET) on October 6 (UTC) to test Winlink
https://www.winlink.org radio messaging to the US mainland, using the
http://KH6YY.net (KH6J) contest station on O'ahu. One of the
premier contest stations in the middle of the Pacific Ocean, KH6YY
offers a commanding propagation path over an expanse of saltwater.
"You have to start with digital modes somewhere," ARRL Pacific Section
Manager Joe Speroni, AH0A, said.
A group of radio amateurs has developed a robust Winlink system in
the Hawaiian Islands to help support communication in a natural
disaster. The Amateur Radio email system is well known for its role in
emergency and disaster relief communications, providing the ability for
users to exchange email with attachments, photos, position reporting,
weather, and information bulletins.
KH6YY sports eight antennas, most on 90-foot towers, and nine operator
positions. For the SET, the station was configured to receive traffic
on 7,100 kHz (dial frequency) in PACTOR, WINMOR, ARDOP, and VARA modes.
The four-element 40-meter beam was aimed at Hilo. Simulating an
internet outage, the setup was used to pass received traffic to a
second 20-meter gateway on 14,100.5 kHz and forwarded to a mainland
gateway with internet access.
Incoming message traffic on 40 meters would be automatically forwarded
to the mainland on 20 meters. Most of the traffic went to gateways in
Mexico and Texas for forwarding to the internet. One user reported
receiving email confirmation that a message was received within
minutes. Read more
