I just read WB4APR message on Solar device HF noise and Han's concurrence.
There is an ever growing problem of noise intrusion on many bands that the
FCC does not appear to care about. Even if we do all the leg work, RDF'ing
the source, and 'giving' the data to the FCC they do nothing.
Now here is where Big-Brother ARRL should stand up and create an open online
reporting DB for HAMs to list the specifics of reoccurring HAM Band Noise,
but not. After X number of concurrence ARRL legal could give the data to FCC
WDC and hope for a resolution.
I've been consulting in the Cleveland area for a over a year during my daily
commute my SUV FTM-400 scan stops on any of the FM SAT birds for a 1/4mile
either side of the I-271 & I-480/Hwy-422 intersection. It is a solid +S40 FM
white noise blanking a wide area of 2meters. Just to the west of this
intersection on the hill is a big commercial comm tower on the University
Hospitals Home Care Services building too. For the FCC this is easy citation
money - if they would ever patrol large city's again.

Burns - Just FYI:
Last AO-92 (14:50z), N1T was full quieting into the bird, but audio was
very low. It got a little louder towards the end of the pass.

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 @????? but it may be on
short notice.

Clayton

Well, I'll have to see how my brand new solar install sounds once it's
operational. The 28 panels with micro-inverters on each panel are
installed, but not energized yet. Being sunny southern California, there is
lots of solar around here - the nearest being two doors east of me. However
I'm not active on HF, so I have no basis for how the noise floor has
changed. Since I have a couple weeks before my system can go on line (main
panel replacement required), I will hook up an HF radio to something and try
to get some before and after noise floor measurements.

Hello,
I have an HT Kenwood TH-7 and now building a 4 element duoband LPDA for

I found a lot of helpful information in the internet. Some infos are in
conflict with other.
Are this infos ok ?
SO50:
Transmit 145.850 MHz fix FM 67.0 Hz, RX from 436.815 MHz to 436.795 MHz
AO91:
Transmit from 435.240 MHz to 435,260 MHz FM 67.0Hz , RX 145.960 MHz fix
AO85:

Great.
This is the kind of measured data we need.
And I do try to remember to tune in the AM band when I drive by a solar
house, but the RFI on AM in my electric car is so high, it is impossible
to tell whether it is comoing from the solar and power lines or my car
itself (on AM).
I know I can hear my array every XX Khz up through 10 meters (I forget the
increment) but since all of my HF dipoles have fallen, I don't have a good
benchmark, and now my neighbor has solar too, so I cant just shut mine
down for quiet. Fortunately, my AC disconnect is right by the kitchen
door if I ever do get back on HF.

All:
I have an ongoing RFI case with the solar panel manufacturer, Solar
Edge. Their field engineer, Tom Simpson, has handled many RFI cases in
the past so they are aware of the problem.
My case is on schedule for repair and Tom assures me that the RFI will
be negligible once the proper RFI suppression methods are installed. The
RFI emanates from a neighbors solar panel system about 150 feet from my
home.
In my case, the noise began the day the system was installed so finding
the source was easy. Knowing who the manufacturer was helped get the
ball rolling. If that's not possible, file a complaint with the FCC and
be persistent. Mike Gruber of the ARRL can assist: mgruber@????.???

Maybe the better solution is a bit more neighborly. Get a group of hams
together to definitively find the source of the interference and go talk
with those who are responsible and be nice about it. Also just because there
is a big tower in the same area as the interference does not mean the tower
is the source. Correlation does not equal causation. Some other things to
consider..... is this broadband noise you describe a constant carrier or
does it rise and fall possibly with another source or sources on another
frequency or frequencies (which ones)? Where specifically does the
interference come from? Can and have you triangulated and tracked it down
definitely to its source of origin and can you prove the geographic source
location with hard data down to a radius of oh at least a couple hundred
feet or so? Most of the people I know that work with radio and
communications systems are pretty conscientious about keeping their systems
in good working order and fixing things (like int
erference) when they know they have a problem. Could it be that no one has
alerted the proper responsible parties in a polite and helpful way with hard
data to back it up and document the issue as to time, place, and
characteristics as documented above? Also note that if the source *is*
found to be something related to emcomm systems they generally have another
reason to be nice, helpful, and responsive to hams. We tend to be their
backup when all hell breaks loose. So go get a group of friends together and
organize a t-hunt. Once you can define exactly where, when, (and how) the
interference occurs, make some polite and inquisitive calls to find the
parties responsible and offer to help resolve the issue however you can. The
relationships you build through this process will likely be long lasting and
have the potential to pay dividends over the long term for the entire
amateur community.

I've had solar panels with optimizers for 4 months and they definitely
cause RFI on both HF and VHF. I think they are Solar Edge panels. I'll
confirm the manufacturer and, if they are Solar Edge panels, I'll
contact Mr. Simpson. I'll send a follow-up to this forum once I found
out more.
By the way, I specifically asked the installer about RFI and he told me
that he never heard any complaints about it. Selective listening?
Of course, I should've done my homework first, but maybe there's a way
to make it work.

Just ran across this handy guide from K6LCS's site, www.work-stat.com:
http://www.work-sat.com/Home_files/FM-VOICE-SATS-1Q-2018b.pdf Sadly
AO-85 is not on the sheet, but it should not be hard to figure out
what to use following the same for the other Fox birds (AO-##'s).

Hi friends,
I procrastinated and now hotel rooms are expensive and few and far
between. I am looking to share a room with someone that already has
one booked. I will split the cost so that would be good for you. I
would prefer the hotel AMSAT has a block in but I know beggars can't
be choosers so I will take what I can get. I will give you a free
Space Comms t-shirt if you want one too :-)
