RESUE RADIO: HAMS RESPOND TO VOLCANO ERUPTION
IN GUATEMALA
Disaster relief services with assistance from
radio amateurs is providing emergency communications in the
wake of the erupting Fuego Volcano in the Republic of
Guatemala. HereÂ’s Fred Vobbe W8HDU...
[Fred:] The largest eruption in three years
took place on Saturday, February 7th and sent a cloud of ash
skyward that forced the closure of the La Aurora
International Airport. Tourists who were hiking on the
volcano and those living in nearby villages had to be
evacuated.
The Club of Amateur Radio of Guatemala
activated emergency station TG0AA on 7.118 MHz. According to
a report to IARU Region 2 Emergency Communications
Coordinator Cesar Pio Santos, HR2P, TG0AA has established a
network with reporting stations located in neighboring Costa
Rica, Mexico, Honduras, Cuba and Venezuela. All are involved
in the post eruption communication effort. A 2 meter repeater
on 147.015 MHz is also in use.
The Fuego volcano sits on the border of the
Guatemalan states of Escuintla, Sacatepequez and
Chimaltenango at a height of 12,346 feet above sea level.
David de Leon is a spokesman for Guatamala's national
disaster preparedness office. He says authorities had already
been put area on alert of the possibility of such an eruption
and had issued instructions urging people to take shelter,
wear masks, cover water tanks and be aware of evacuation
routes. Local experts expect the emergency to ease to allow a
clean-up of the area to begin. For the Amateur Radio
Newsline, IÂ’m Fred Vobbe W8HDU in Lima, Ohio. (VK3PC, other

RESTRUCTURING: AMATEUR SUPER HIGH FREQUENCY
BAND COULD FACE UNWANTED CHANGE
A super high frequency ham radio band here in
the United States could be in peril due to spectrum needed
for vehicular radar systems.
Skeeter: ]The FCC is seeking comment on issues
involving expanded use of various radar applications in the
76 to 81 GHz band which Amateur Radio shares with other
services.
The band--from 77.5 to 78 GHz--is allocated to
the Amateur and Amateur Satellite services on a primary
basis, and to the Radio Astronomy and Space Research services
on a secondary basis. Among many issues, the FCC seeks
comment on the possibility of reallocating the Amateur Radio
and Amateur Satellite services from 76 to 81 GHz, and it asks
for suggestions on alternative spectrum that it might
make available in this general region.
The FCC Notice of Proposed Rule Making and
Report and Order is in response to a Petition for Rulemaking
designated RM-11666 that was filed in 2012 by Robert Bosch
LLC. Two petitions for reconsideration of the CommissionÂ’s
2012 Report and Order addressing vehicular radar systems in
the 76 to 77 GHz band were incorporated at earlier
proceedings.
[Jim:] ThatÂ’s NewslineÂ’s Skeeter
Nash N5ASH. In its summary the FCC says that its goal is to
adopt rules that address amateur use, including Amateur
Satellite use, within the 76 to 81 GHz band in a
comprehensive and consistent manner. An in-depth look at this
situation is on the ARRL website at tinyurl.com/n9aw83y

DX: NEVASSA ISLAND K1N WINDING DOWN
By the time many of you hear this, the long
awaited K1N Nevassa Island DXpedition will be QRTÂ…
[Don:] Wolf Harranth, OE1WHC from the Amateur
Radio Section of the Austrian Broadcasting Corporation sent
Ohio Penn DX Newsletter a press release based on a satellite
phone interview with co team leader Glenn Johnson,
W-zero-G-J .
In short, Johnson says that the K1N will begin
winding down on Friday, February 13th. The team will start by
sending their unneeded supplies back to Jamaica. On Saturday,
the 14th K-one-N operations will still be on the air, but
some of the personnel will begin to leave the island. All
radio equipment will remain on the island until daybreak
Sunday, when operations will go QRT.
In other developments, on February 10th Johnson
posted to the DXpedition website that the operation was
approaching 96,000 QSO's and hoped to pass the 100,000 point
later that day. Also that the fierce pile-ups were
continuing with what he called walls of European stations
that are being worked each day until the bands close. He
also thanked the world wide ham community for its
cooperation while working in certain propagation windows,
especially to Japan. For the Amateur Radio Newsline, IÂ’m Don

RADIO LAW: FCC PROPOSES TO RETURN HAM TO TECH
PRIVELEGES AFTER VEC ERROR DISCOVRED
The FCC has proposed to modify the license of
Brent D. Cullen, KD0YLM, to show Technician Class operator
privileges due to a data filing error made by the
administering VEC.
On December 3, 2014, the American Radio Relay
League Volunteer Examiner Coordinator sent an electronic data
file to the Commission requesting that CullenÂ’s operator
license for amateur station KD0YLM be modified to upgrade
from Technician Class to General Class amateur radio operator
privileges. Based on this application, the Commission granted
Cullen a General Class amateur service operator license on
December 3, 2014.
But in correspondence dated this past January
16, the ARRL notified the Commission that there was an error
in the December 3, 2014 data file and that an applicant
other than Cullen had qualified for a General Class
operator license. The ARRL noted that a correction was
filed, resulting in the other unnamed licensee receiving
the operator license for which he had qualified, but
that CullenÂ’s operator privileges had not been returned
to Technician Class operator privileges. As such
Cullen appears to be currently authorized to operate with
General Class operator privileges due to an error made during
the application process. Now the FCC says it wants to
correct that clerical mistake. (FCC)

REGULATORY: FCC ASKS FUNDING FOR NEW
HEADQUARTERS
The FCC says that it may have to move to a new
headquarters in the Washington, DC, area and that it needs
funding to make this happen. This came to light when the
administration asked for $388,000,000 for Fiscal Year 2016 in
the President's budget, which is what the FCC had
proposed.
That amount is up from the more than 375
million dollars it asked for in Fiscal Year 2015 and is
attributable almost entirely the what the FCC says it needs
to either move to a new headquarters or re-stacking the
current space given the expiration of its lease. Doing either
should save the FCC $119 million over 15 years, the agency
says.
The FCC's budget is entirely covered by
regulatory fees, in addition to which the commission will be
generating billions for the treasury through its ongoing
spectrum auctions. (Published news reports)

PROPAGATION: FCC RENEWS ONLY US 4 METER
EXPERIMENTAL BEACON PERMIT
A beacon on the 4 meter band will continue to

[Skeeter:] Brian Justin, WA1ZMS reports that
the Experimental License for the WG2XPN one-way beacon
operation on 70.005MHz has been renewed until May 1st of
2017. As such, it gives the only 4 meter North American
beacon a chance to be heard in Europe for another 2 years.
WG2XPN runs 3 kilowatts of Effective Radiated
Power from United States Grid Square FM Oh 7 fm in Virginia,
beaming East across the Atlantic Ocean. WA1ZMS says that
thanks go out to both the FCC and the Society of Broadcast
Engineers for their continued support of this project as the
spectrum in which WG2XPN operates is still reserved for use
by telecasters, and no United States 4 meter ham band appears
possible in the near future. For the Amateur Radio Newsline,

EMERGING TECHNOLOGY: PUTTING THE INTERNET INTO
EARTH ORBIT
Space exploration company Virgin Galactic and
chip-maker Qualcomm have announced their backing of a venture
called OneWeb. Their idea is to put 648 satellites in orbit
about 750 miles above Earth's surface, where the RF round
trip time is just a few thousands of a second, Both companies
say that this is an apropos altitude for any online
application.
But the two companies are not alone. Not to be
outdone, SpaceX immediately announced its own plan to do the
same, but upping the numbers by building and launching
4000 satellites to a similar altitude.
While some form of radio communications might
seem to be the obvious form of connection between Earthbound
users and a satellite system, other systems are also under
consideration. This includes a possible optical
communications infrastructure.
No matter what is decided, the concept makes
for an interesting expansion of high speed Internet access.
An in-depth article on these proposals and other ideas can be
found in an article in New Scientist magazine. Its on the web

The Iranian satellite Fajr or ‘Dawn’ was
launched on February 2nd at 08:50 UTC from the Imam Khomeini
Space Center. The 50 kilogram bird was carried to space on a
Safir launcher into an initial orbit of 223 km by 470 km with
an inclination of 55.5°.
This is IranÂ’s fourth satellite and has
propulsion in the form of a cold gas thruster. Presumably the
thruster will be used to circularize the orbit at around 470
km which may give it a lifetime of over a year. (AMSAT)

THAT FINAL ITEM: NEW RASPBERRY PI 2 CAN REBOOT
IF EPOSED TO XENON CAMERA FLASH
And finally this week it appears that the
latest version of Raspberry Pi's mini computer appears to be
camera shy. At least the Raspberry Pi 2 does not like the
spurt of high intensity light from Xenon camera flashes and
may reboot itself when exposed to it. With more, here is
Heather Embee KB3TZDÂ…
[Heather:] The glitch is a result of the
photoelectric effect phenomenon. Raspberry Pi creator Eben
Upton admitted to the BBC that he had not been aware that the
Raspberry Pi 2 would be sensitive to camera flashes, but that
he was not too upset about it. Rather, he termed it an
unintentional educational bonus and an interesting
demonstration of the photoelectric effect.
According to the the Southgate News, it was
Essex radio amateur Peter Onion, G0DZB, who discovered the
Raspberry Pi 2 reboots when photographed using a Xenon flash.
The reason seems to be that a chip on the board is not
light-resistant. The simple fix appears to be covering the
offending integrated circuit with something like Blu Tak. Blu
Tak is a reusable pressure-sensitive putty-like adhesive
commonly used to attach lightweight objects such as posters
or sheets of paper to walls or other dry surfaces; but it
also seems to have the ability to block out a flash of Xenon
light. For Newsline, IÂ’m Heather Embee KB3TZD in
Warwick, Pennsylvania.
[Jim:] The company that created the Raspberry
Pi2 says that it has has received in excess of 300,000 orders
for the new $35 device since its launch two weeks ago. More
about this story is on the web at

W5KUB.COM is now doing a live weekly ham radio webcast every Tuesday night

and we have special guests each week covering a wide range of topics.
During the last half of the show, we allow any viewer to come into our
webcast remotely and be on the show. We are also looking for anyone who
wants to schedule maybe 10-20 minutes on the show and give a discussion,
presentation, etc. We are looking for all subjects, DXing, homebrewing,

using skype. If you are interested send email to w5kub. Im good in qrz
