AMSAT News Service Bulletin 126.01
From AMSAT HQ KENSINGTON, MD.
DATE May 6, 2018
To All RADIO AMATEURS
BID: $ANS-126.01
The end of daytime HF
The National Electric Code now requires electronics on every module
of a
solar array communicating via signalling on the DC power lines to
assure
EACH pair of panels can shut down independently. This is to make all
possible faults never allow more than 80 volts anywhere in the system.
This is effective 1 Jan 2019
This is the nail in the coffin of simple DC series string arrays
which are
the quietest systems and almost demands microinverters or optimizers
on
every panel. Refer to the QST article a few years ago about how
disastrous
optimizers are to RFI and HF operations with modules all over the
roof..
Here is the Solar news:
https://solarbuildermag.com/bos/nec-2017-module-level-solar-system-
shutdown/
Also, what is going to happen to an array that has signaling all
over it in
the near field of HF?
Although you can avoid it by going solar before then, you may have
problems
when your neighbors go later.
I hate to be an alarmist but we all know what happens when ham
radio and
commercial systems are incompatible and even though Ham radio might
be in
the right, we are only 1 in 600 and no one is going to side with us.
We took on broadband over power and squelched that dumb idea, but
now this
has the potential for equal demise of Ham radio. It should be
fixable, but
we also know that there is high competition in the solar market and
the
modules that are made the cheapest will be popular and will likely
not be
adequately filtered.
Sorry for posting to the AMSAT-bb but it is the only HAM email
reflector I
subscribe to.
If nothing else, we need to find out what systems are terrible
emitters and
nip them in the bud. Maybe all it takes is driving by solar systems
you
see and turing on your AM radio on a weak signal channel and seeing
if the
background noise peaks near that home. But also it has individual
peaks,
so it might also be nice to tune around too find the max and then
check the
range. I find the noise can go hundreds of feet along the power
lines....
You cant miss em... just sounds like a 60 Hz buzz on all the
harmonics of
the inverter switching frequency.

EL58hx Grid Expedition - 25-27 May
The activation of maidenhead grid square EL58hx by W5PFG & AC0RA is
just
three weeks away. Even if you are not a grid or awards chaser, we
would
love to work you during this expedition via satellite. There are no
permanent residents of this grid square, as the majority of it is
open
water in the Gulf of Mexico. What little land in EL58 is sandbar at
mouth of the Mississippi River and accessible only by boat. See here:
http://qthlocator.free.fr/index.php?locator=el58hx
During the entire expedition, we will be land-based in the grid,
meaning
this activation will count as Louisiana, Plaquemines Parish (County),
USA. It counts as Islands on the Air IOTA NA-168, Burwood Island. If
you
participate in the 2018 ARRL International Grid Chase, this might be
your only opportunity to work EL58.
Operating activity is estimated to begin around 23:00 UTC on 25 May.
There are some variability in our arrival time and it will take us
some
time to prepare the site for operation. We will likely conclude
operations around 15:00 UTC on 27 May.
There are a total of 110 satellite passes predicted, 42 being FM.
While
we won't work every one of those, we should be on the ones that fall
into good times and the best footprints over population centers. The
list below are satellites we plan to utilize:
FM: SO-50, AO-85, AO-91, AO-92
SSB: AO-7, FO-29, AO-73, XW-2A, XW-2B, XW-2C, XW-2F, CAS-4B
Skeds are available for DX and stations greater than 6000 kms
distance
from EL58hx. Sked via direct email only to w5pfg at arrl dot net.
Even if you worked the previous EL58 trip (K5L/mm), we'd love to work
you again. This expedition we will use callsign W5PFG on satellites
and
AC0RA on 6m. We are hoping to work and confirm as many grid squares
as
possible, so if you want to work us from a nearby grid line to your
home
QTH, it is appreciated!
AC0RA is responsible for the 6m side of our activation. You may hear
either of us on 20m and 40m. Any one who works us is encourage to
spot us.
I may activate other grids in route to EL58, especially Friday
morning
the 25th. I'll try to announce those via Twitter @w5pfg but it may
be on
short notice.

Introducing the Satellite FAQ and How-To wiki
http://sats.wikidot.com/
The main content so far:
= What apps can I use to track satellites? =
* http://sats.wikidot.com/what-apps-can-i-use-to-track-satellites
* A table of Android/iOS mobile apps with supported/not supported
checkmarks for various features. I don't have iOS so I had to put
question marks on a lot of features for those apps.
* If you know the status of the features let me know off list, or I
can add you to the wiki so you can edit it yourself.
= How do you know when the ISS is transmitting SSTV? =
* http://sats.wikidot.com/how-do-you-know-when-the-iss-is-
transmitting-sstv
* Includes instructions on how to setup email notifications on the RSS
feed of ariss-sstv.blogspot.com website using blogtrottr so you can be
emailed when new events are announced.
= How do you add 2 meter only digipeaters to SatPC32 =
* http://sats.wikidot.com/how-do-you-add-add-2-meter-only-
digipeaters-to-satpc32
* I just added this based on an email from 2 hours ago
= How to create multiple profiles in GoSatWatch =
* http://sats.wikidot.com/gosatwatch:multiple-profiles
* You can create the equivalent of profiles in the GoSatWatch by
cloning an element set then selecting only those satellites of
interest.
* Brad WF7T created this tutorial
Brad, WF7T and I started this wiki.The purpose is to document answers
to Frequently Asked Questions (FAQs) across the various forums like
amsat-bb, the AMSAT-NA Facebook group, twitter, QRZ.com forums, etc.
How-Tos are also acceptable. The goal is not to be a comprehensive
source of amateur satellite information (especially not lists of all
the sats, as that info is on many other sources), just to supplement
what is already out there and provide a place to collect commonly
requested information. More information on the intention/philosophy of
the wiki can be found here:
http://sats.wikidot.com/about
If you want to add stuff or edit the wiki, please create an account on
wikidot and let me or Brad know your username/email address and we can
add you.
On the To-Do list [1] I have a goal to make a new page with a list of
full duplex HTs. I know a list of these HTs already is on the web but
I don't believe it's updated. I also know Patrick, WD9EWK has a lot of
detailed info on various Chinese radios. All of this could be
summarized and updated as new HTs come out. If you want to start it
"that would be great." ;-)

ARRL Executive Committee Discussion of Small Satellite NPRM
The ARRL Executive Committee meeting on April 21 in Windsor,
Connecticut, discussed the FCC's recent Notice of Proposed
Rulemaking (NPRM) regarding the deployment of "small satellites"
by colleges, universities, and commercial entities using experi-
mental licenses on Amateur Radio spectrum.
The Committee was told that the International Amateur Radio Union
(IARU) has changed its previous policy regarding the coordination
of small satellites (CubeSats), and that FCC policy is overly
restrictive in some respects and insufficiently protective against
commercial exploitation of amateur spectrum in other respects.
AMSAT has requested ARRL's input.
The Committee agreed that ARRL's comments should reflect their
support for World Radiocommunication Conference 2015 Resolution
659 and IARU policies.
In addition, ARRL (a) will support and encourage college and
university Amateur Radio experiments where the sponsor of the
experiment is an amateur licensee and all operation is in amateur
spectrum, and (b) will discourage commercial or Part 5 experimental
operations using Amateur Radio spectrum.
******* Editor's note *******
The ARRL plans to file a comment on the FCC's Part 25 Notice of
Proposed Rulemaking (NPRM). AMSAT may file comments as well, though
the focus of those comments will be about any potential inference to
the Part 97, Amateur Radio Service. AMSAT and the ARRL have been in
contact discussing this Part 25 NPRM. Until this NPRM has been
published in the Federal Register, the comment period has not opened.
Once published, the comment period will be open for 45 days.
[ANS thanks the ARRL for the above information]
