Thanks to all who worked or tried to work me mobile
on my trip back to Cleveland from Melbourne, Florida.
I operated while in motion on SO-67, AO-27 and AO-51.
Equipment was the Kenwood V7A and a Larsen dual band
mag mount on the trunk lid, no preamps.
SO-67 has a dynamite signal and it was easy to hear the
bird, however, with the road noise at 70mph, the weaker
audio made it difficult to copy those whose audio was on
the weak side to begin with. Even so I made some good
contacts on two passes.
AO-27 was also very good although not as strong as SO-67.
I did manage to work KD8KSN while in EM94 right at the
end of the pass.
AO-51 was the real workhorse with it's high power output.
Copying in the mobile was fairly good but you could really
hear the antenna elevation pattern effect as the bird went
over. It was really nice to work Yuri, UT1FG/MM, while in
EM95 on I-77 in Charlotte NC.
The last AO-51 pass was blocked right in the middle of the pass
because I came up on the 5 mile grade over the Blue Ridge Parkway.
I kept hearing WA4HFN calling and finally got into the bird just
seconds before it disappeared over the ridge. This was in EM96
just inside the Virginia line. CO6CBF was also worked earlier on
this pass.
Headphones would have helped a lot. I didn't think to have them
available. More contacts could have been made if I had been able
to stop since the mobile fading would have been minimized.
If anyone needs a card for a new grid, just send me an email with
the qso info. No SASE needed.
The trip was 1100 miles and took 17 hours. It was in the 30's
here. Yuk!
73,
John K8YSE

Hi Dom,
I was pondering the temp reduction for the tip after we had our
discussion the other day...
The current is fully off for half of the cycle and reduced by some
percentage on the other half, but I can't remember the procedure to
determine it....The figure .7 sticks in my mind...
That percentage would probably be close to the idling tip
temperature, influenced by radiation and some other factors of course...
These kind of things (queries) pop in, but the answerers don't pop in
as easily any more!!
Ready for a math lesson, tnx!!

All I has wifi connection issues and was going to post my passes for today.
Well in the mean time a weather front has come in and there is very rain
happening now as well as an AO51 pass in a few minutes.
Will have to play things by ear to see if things clear up.
If they do I will try:
FO29 at 22:45Z
SO-67 at 0128Z 4/3/11
Maybe VO-52 02:00
Again there is no guarantee I will be on due to the ongoing rain downpour. I
am
available tomorrow afternoon/evening. I will know schedule noon local time
tomorrow.

An updated version (2893) was released a few days ago, and now does LoTW
upload and download.
There has also been an awards function for some time now, which can be
tailored for just about any award you'd like, including, but not limited to
grids.

Hi Dave, WB6LLO
The figure .7 sticks in your mind to remember the meaning of the
term rms or Root Mean Squared voltage as explained in the
following web page.
http://www.practicalphysics.org/go/Guidance_107.html
Supposing that your soldering iron is supplied by 220 Vac rms with
a single diode in series the current is fully off for half of the cycle so
that the output voltage of a half wave rectifier applied to the resistor
of your iron tip can be calculated with the following two equations.
Vpeak 220 x 1.41
Vdc = ----------- = ---------------- = 99 V dc
3.14 3.14
and
Vpeak 220 x 1.41
Vrms = ----------- = ----------------- = 155 Vrms
2 2
and this is why your soldering iron is not so hot as without the diode
in series of it.
The same circuit with a diode in series to a AC motor and a heating
resistor is used into any two speed blower to dry hair.

ARISSat-1 Operations Possible 11-13 April UTC

April 3, 2011

BID: $ANS-093.01
The ARISSat-1 satellite, presently still inside the ISS, will be turned on and
use an external antenna from the afternoon of 11 April UTC through the morning
of 13 April to celebrate the 50th anniversary of Yuri Gagarin's first manned
space flight. More specific times will be announced as they become available.
AMSAT will support this event and issue
certificates to those stations reporting
reception of the ARISSat-1 signals. Roscosmos has announced that the satellite
will be deployed into orbit during the next EVA in July of this year.
The release of a development version of the
BPSK/CW decoding software next week.
Schedule specifics of the 12 April operation transmissions are not available
yet. These will be posted on the AMSAT and ARISSat1 web sites and in ANS when
available.
The transmissions on the 12th will see ARISSat-1 in low power mode, this means
40-60 secs on, 2 minutes off. It should be a challenge to find and tune the CW
signal then decode some BPSK data during the short on times. This mode was
developed to be used when the batteries are low or the satellite is in
eclipse.
During this even data and information will be collected to improve the BPSK
demodulating, decoding and display software. Those with the FUNcube Dongle and
SDR-IQ and variants are encouraged to record the wideband transmissions to
help
us better understand the signals and improve the ground station software.
Information on where to send the recordings will be available on the AMSAT and
ARISSat1 Web sites.

Can you be in at once? I mean we are pretty small on the scale of things, so
how can you give out more than one grid square at a time?? I mean really, I
hear it all the time. What do you do, put your antenna on one grid square,
run some coax over and set your radio up on the other grid? Ok boys, hear is
DM09 and DM08!!! Her - ert duh, how about I drive to where the four corners
of four grids meet, stand right in the middle of that and give out all four
of them at once?
Is this how it is done. Just does not seem right to me, seems like cheating.
Seriously...Is there not some kind of rules or something?
I think I will leave it at that before I get too offensive.

Yes. It happens frequently.
>From the VUCC rules:
Stations who claim to operate from more than one grid locator simultaneously
(i.e., from the boundary between two grid
locators or from the intersection of four grid locators) must be physically
present in all locators to give multiple locator
credit with a single contact. These stations should be prepared to validate
their claim. For a mobile station, this means
parking the vehicle exactly on the line or corner. For a portable station,
this means that the total area occupied by the
station's physical setup, including operating position(s), power source(s),
and antenna(s), must occupy some portion of each
of the two/four grid squares simultaneously. Operators of boundary/corner
stations should be prepared to provide evidence of
meeting the simultaneous occupation test if called upon to do so. Two
photographs - one showing the placement of the GPS
receiver in the station setup, and a close-up legibly showing the GPS
reading - are typically needed as evidence of
compliance. Video footage showing an overview of the operating site and
then, uncut and in real time, zooming in on the GPS
display coordinates is even better.

Hi Kevin,
Here are the VUCC rules for operating from a boundary:
http://www.arrl.org/files/file/Awards/VUCC%20Rules%202011_Rev%2020110215.pdf
4. (e) Stations who claim to operate from more than one grid locator
simultaneously (i.e., from the boundary between two
grid locators or from the intersection of four grid locators) must be
physically present in all locators to give multiple
locator credit with a single contact. These stations should be prepared to
validate their claim. For a mobile station,
this means parking the vehicle exactly on the line or corner. For a portable
station, this means that the total area
occupied by the station's physical setup, including operating position(s),
power source(s), and antenna(s), must
occupy some portion of each of the two/four grid squares simultaneously.
Operators of boundary/corner stations
should be prepared to provide evidence of meeting the simultaneous
occupation test if called upon to do so. Two
photographs ? one showing the placement of the GPS receiver in the station
setup, and a close-up legibly showing
the GPS reading ? are typically needed as evidence of compliance. Video
footage showing an overview of the
operating site and then, uncut and in real time, zooming in on the GPS
display coordinates is even better.
(f) Grid boundary lines and grid corners must be established using a GPS
receiver whose map datum is set to WGS84,
the global default for current GPS receivers. The GPS receiver should be set
to use WAAS (Wide Area Augmentation
System) if so equipped, since this improves the error figure to as little as
5 feet. In no case may the GPS receiver
show an error figure in excess of 20 feet. Any modern GPS receiver equipped
with WAAS will easily meet this
requirement, as will most older units without WAAS.
Maidenhead grids measure 1 degree latitude x 2 degrees longitude, so it is
possible to fine the intersection/boundary using a standard GOS receiver.
73,
Zack

Can you be in at once? I mean we are pretty small on the scale of things, so
how can you give out more than one grid square at a time?? I mean really, I

run some coax over and set your radio up on the other grid? Ok boys, hear is
DM09 and DM08!!! Her - ert duh, how about I drive to where the four corners
of four grids meet, stand right in the middle of that and give out all four
of them at once?
Is this how it is done. Just does not seem right to me, seems like cheating.
Seriously...Is there not some kind of rules or something?
I think I will leave it at that before I get too offensive.

Also check out some of the picture on my QRZ page (towards the top). Notice
the lat/lon coordinates from the boundaries. K8YSE Has one on his QRZ page
of an intersection.

Kevin,

Yes, you can.

You can do that, or just put your station right on the boundary or where
the four grids intersect. As others have already cited, the VUCC rules
spell out how you would do that, how to document that you are on the
grid boundary or intersection, and what's needed from a GPS receiver
for that documentation.
The VUCC rules indicate you can either record a video that shows the
station and a closeup of the GPS receiver sitting in the station with the
latitude/longitude on the display, or take a couple of photos of the station
including the GPS receiver along with a closeup of the GPS receiver's
display. I opt for the latter, as that takes less memory on the camera
(or phone) than a video clip. Photos are easier to e-mail if anyone has
a question regarding my station location. They're also easier to work
with when I make my QSL cards, where I generally include the GPS
latitude/longitude readout on the card along with a description of my
location.
I have posted examples of the photographic documentation from a
couple of these situations on a web page. These photos were from my
trip to Chicago last October, operating from the EN40tx/EN41ta grid
boundary in western Illinois and the EN51xx/EN52xa/EN61ax/EN62aa
4-grid intersection in the Chicago area during the 2010 AMSAT Space
Symposium. The photos are at:
http://www.qsl.net/wd9ewk/multi-grids/
The "-1" photos are the closeups of the GPS display at each location.
The GPS shows latitude/longitude, along with the accuracy figure
mentioned in the VUCC rules. That figure is in the upper-right corner
of those photos. The "-2" photos are the wider-angle views of my
station with the GPS receiver in there. I had my GPS powered on
for at least 30 minutes before reaching these locations, in order for
the GPS to be stable and have that low accuracy figure.
If you want to go to 4-grid intersections, take a look at this web site:
http://www.confluence.org/
Chances are good you can get some hints and advice from those who
have already visited these locations in the past. Make sure to have the
latitude/longitude for the intersection when using this site.
73!
