Colorado ATV Group Transmits Images from CalWood Fire
Radio amateurs in Colorado took advantage of amateur television (ATV)
to observe recent forest fires. Boulder ATV repeater W0BTV has been
transmitting views of the CalWood fire, considered 26 percent contained
as of mid-week. The camera is at KH6HTV, southeast of Boulder and 13 -
15 miles from the fire. Using a telephoto lens, the KH6HTV TV camera
was able to view the fire along the Front Range as it approached the
first ridge of the Rocky Mountain foothills. TV images are being
received at the Boulder [IMG]County ARES (BCARES) command post in the
Boulder County Emergency Operations Center (EOC), where they are
displayed on a large-screen monitor.
California and Oregon have been experiencing major forest fires for the
past couple of months. Fire hit Boulder County on October 17, when the
CalWood fire broke out northwest of Boulder. By mid-week, the fire had
consumed some 10,000 acres of forest, sparked a prairie fire outbreak,
and destroyed more than 2 dozen homes.
The W0BTV repeater video is being streamed live over the British
Amateur Television Club (BATC) server in the UK. The right audio
channel carries live audio from the BCARES 2-meter repeater, with the
emergency net traffic.
Not much was to be seen on the ATV repeater's video image at mid-week,
as a cold front had rolled in, bringing light rain and fog, helping to
suppress the fire.
The Boulder ATV club has installed a new 5.9 GHz FM-TV beacon
transmitter on a government building for the purposes of encouraging
microwave experimentation, to get hams to try ATV (especially with
low-cost FM-TV gear now available for drones), to use as a known signal
source for testing antennas and receivers, and to increase usage of the
microwave bands, which are under threat. -- Thanks to the Boulder
Amateur Television Club Repeater
Nationwide Red Cross Emergency Communications Drill Set for November 14
The nationwide American Red Cross Emergency Communications Fall Drill,
a joint exercise with ARRL Amateur Radio Emergency Service (ARES^(R))
groups, is set to take place on November 14. This exercise evolved from
the highly successful spring drill that attracted hundreds of
participants from some 40 states and Puerto Rico.
The fall drill will be a Winlink-specific event with these goals: (1)
pass traditional American Red Cross (ARC) forms from as many states and
as many radio amateurs as possible to one of six division
clearinghouses, and (2), bring as many radio operators as possible up
to a "basic" level of Winlink proficiency. A series of Winlink
Workshops is held each Thursday at 0100 UTC on Zoom.
Winlink Proficiency Goals have been drafted, a Winlink technical
support team has been formed, and Metrics for Drill Success have been
developed. The proficiency goals are established as a training
guideline and references online training resources. Many hams new to
Winlink may find these resources helpful.
More than 300 radio amateurs have signed up for the event, and some 100
volunteers showed up for a pre-drill briefing call earlier this month.
Another briefing call will be held in early November.
This event is open to all radio amateurs.
For more information, contact Mike Walters, W8ZY, with ARES-related
questions, or Wayne Robertson, K4WK, with Red Cross-related topics. --

Active LF Operator Offers vice on New FST4 and FST4W Protocols
The recent beta release WSJT-X version 2.3.0-rc1 (release candidate 1)
digital software suite includes two new protocols, FST4 and FST4W. FST4
is for two-way contacts, while FST4W is for "quasi-beacon" style
transmissions. Both modes offer a range of options for T/R-sequence
lengths and threshold decoding sensitivities extending well into the
-40 dB range, developers said, as well as a wide variety of parameters
that can be tweaked, such as transmission time, bandwidth, and so
forth. On the WSJT-X development reflector, Paul Kelley, N1BUG,
discussed whether the wide variety of options are really necessary or a
stumbling block to two uncoordinated stations attempting a contact.
Kelley said he understands the concern regarding the transmission
times, but, as a "very active" 2200-meter operator, he advises that the
new protocols were developed with the LF and MF bands in mind.
"LF and MF are not HF," Kelley said. "There is no one-size-fits-all for
these bands. On HF, you may be able to work the whole world with one
relatively fast speed. It is not so down here."
Kelley pointed out that MF operators are limited to 5 W EIRP on 630
meters and a mere 1 W EIRP on 2200 meters. Working "real DX" requires
some specialized modes, plus determination and patience.
"One would probably not want to use anything slower than 120 seconds
for QSOs with well-equipped stations at 1,000 kilometers (620 miles)
distance," he said. "It would be very boring and waste a lot of time.
But for some DX paths on 2200 meters, only 1,800- or 900-second periods
would offer any hope for success. It's not so boring when you are about
to set a new world record or make a personal best DX QSO. We need this
flexibility."
Kelley predicts that some new conventions will emerge over time -- for
example, 900- and 1,800-second periods might not see much use on 630
meters, while most of the faster choices probably will. "On 2200
meters, I think all four FST4W speeds will be quite useful," he said.
"It may be that the fastest FST4 options won't see a lot of use on 2200
meters, but it may be too early to know for sure." -- Thanks to the
ARRL Contest Update

FCC Headquarters Relocates
FCC Headquarters has moved. The new address is 45 L St. NE, Washington,
DC 20554. The change is effective immediately. The FCC announced plans
to move last spring, but the transition was delayed by the COVID-19
pandemic.
The FCC, like many federal agencies, has its own ZIP code, so there
will be no disruption in mail delivery sent by USPS to the former
address. The FCC still prohibits the delivery of hand-carried
documents, and all COVID-19 restrictions or instructions regarding
access to FCC facilities remain in place at the new location.
"The FCC continues to balance its efforts to be accessible to the
public with the need for heightened security and health and safety
measures and encourages the use of the Commission's Electronic Comment
Filing System (ECFS) to facilitate the filing of applications and other
documents when possible," the FCC said in an October 15 Public Notice.
Due to the pandemic, the move was accomplished by professional movers
without the presence of any employees, all of whom had been working
from home. An attempt was made during the summer to let employees back
into headquarters for a day to pack up their offices and remove
personal belongings, but that plan had to be scrapped after several
employees tested positive for COVID-19.
Most FCC staff continue to work from home and are not expected to be
physically present in their new offices before next June.
In anticipation of the planned move, the FCC last spring also announced
the adoption of a new FCC seal. The redesign is the product of an
agency-wide contest that solicited proposals from employees and
contractors.
IARU Official Challenges Member-Societies to Focus on "Tomorrow" Issues
International Amateur Radio Union (IARU) Region 1 President Don
Beattie, G3BJ, urged member-societies attending the virtual Region 1
General Conference on October 16 to keep an eye on future issues
affecting amateur radio and IARU Region 1 (Europe, Africa, and the
Mideast). In closing the 6-day meeting, Beattie said he looked forward
to the planned in-person workshop on the future of amateur radio, set
for next year, and expressed the hope that the COVID-19 situation would
allow the event to go forward as early as possible.
Beattie also challenged member-societies to increase their focus on
"'tomorrow' issues -- tomorrow's people, tomorrow's technologies,
tomorrow's activities, and tomorrow's ways of communicating with those
we represent." He also asked member-societies to communicate with their
younger members and "take account of their views to help reshape their
societies for the future."
The week-long virtual assembly included discussion of papers submitted
by member-societies, the Executive Committee, and other IARU
components. This resulted in some 50 recommendations to the Final
Plenary Meeting in areas of finance, HF, VHF, EMC, youth, and IARU
Region 1 governance. Some 120 delegates were present for the Plenary,
and heads of national delegations considered and voted on these
recommendations, which will result in actions and policy changes in
IARU Region 1.
Some new appointments were made in IARU Region 1, to succeed people who
were retiring from their roles. The new appointments were:
* Dick Harms, PA2DW, chair, IARU Region 1 VHF Committee
* Wolf Mahr, OE1MHZ, chair, IARU Region 1 EMC Committee
* Barry Lewis, G4SJH, chair, IARU Spectrum and Regulatory Liaison
Committee
* Philipp Springer, DK6SP, chair, IARU Region 1 Youth Working Group
* Gaspar Mir¢, EA6AMM, IARU Region 1 Monitoring System (IARUMS)
Coordinator
Beattie thanked those retiring and recognized their contributions.
"Looking back on our first Virtual General Conference, delegates agreed
that it was different from General Conferences held in the past,"
Beattie said. "Although we did not have opportunities for social
interaction between delegates, we can look back on a successful and
very effective meeting. We are already looking forward to our hopefully
in-person workshop in Novi Sad, Serbia, in 2021."
Papers discussed at the conference are available for download. --

WSJT-X Developer Expresses Puzzlement over FT8 Contest Use
WSJT-X co-developer Joe Taylor, K1JT, recently expressed puzzlement
over the use of FT8 in contests -- rather than FT4, which was designed
for contesting.
"I fail to understand why anyone who uses FT8 in a contest would fail
to use FT4 for much of the time," Taylor said. "FT4 is about 3 dB less
sensitive than FT8, but it's twice as fast."
Taylor offered the comment in the Mt. Airy VHF Society's October 2020
Cheese Bits, regarding the September ARRL VHF Contest. Taylor said a
large fraction of stations that are worked with FT8 are much more than
3 dB above the FT4 decoding threshold.
"With FT4, you can still work anyone that can be worked with CW, and
near the CW threshold, you'll do it faster using FT4," he said. "And
with FT4, you can work stations that are far weaker (by ~20 dB) than
what's necessary for SSB. When I did work other stations with FT4, I
did it by transmitting the FT8 message 'K1JT FT4 318.'" Taylor said
he'd then move to 50.318 MHz FT4, and several contesters followed him
there. "Many more would have made it much more fruitful," he said.
"For speed, flexibility, and ease of running the bands, yes, you should
use SSB and CW when there are stations to work," Taylor said in
summary. "When you run out of those, use FT8 and especially FT4."
Taylor also remarked, "In my 80th year, I can no longer call on my past
stamina for contesting."
Japan's "Experience Stations" Enable Contacts Between Two Unlicensed
Girls
What is believed to be the first ham radio contact in Japan between two
unlicensed individuals took place on October 11 between "Experience
Stations" 8J1YAB/1 and 8J3YAA/3. Both were licensed through the 7-CALL
Amateur Radio Club.
"Today is my first amateur radio," one young girl said, as she wielded
the mic. "Me too," the girl on the other end replied. The contact, on
40-meter SSB, was between Tokyo and Osaka. Licensed individuals were on
both ends of the contact to serve as control operators. One operator
reported, "There was applause at the Osaka venue."
"Congratulations on your first attempt and great success," Toshiaki
Tsunashima, JA4DLF, tweeted.
Satoshi Yamaguchi, 7M4VQJ, the President of 7-CALL Amateur Radio Club,
called CQ and made initial contact with with Yasuyuki Suzuki, JJ0RHL,
from the "sister station" 8J2YAB/1 in Tokyo. The licensed supervisor of
8J3YAA/3 in Osaka was Sam Yoshida, JS3CEQ.The Experience Stations are
licensed under special permission, allowing unlicensed people to
operate the station under the supervising of a licensed amateur. The
idea is to promote experience with wireless communication technology.
Before the noteworthy contact, the first contact by an unlicensed guest
operator was made with 8J1JARL, a Japan Amateur Radio League special
event station hosted by the Kanto Region Society of JARL, and operated
by Yamaguchi Takahiko, JL1USZ.
Puntoshi, JN1VVR, remarked on Twitter, "Thank you for your hard work.
It is necessary and important to prepare and experiment so that
[unlicensed] people can feel the excitement of 'something amazing'
while watching the operation. This [Experience Station] operation has
just begun, and the know-how that will be accumulated for the future is
important."
