Yesterday I was working/listening and waiting AO7 SSB VHF/UHF, One
station was booming in. Call sign intentionally not posted to skip their
possible embarrassment. Midway thru the pass the signals went dead. No
receive at all. If I recall from reading my theory he was likely hitting
bird with 100 watts and used up the batteries in bird.
Am I on track?
Also, last week I was working a 6 land station who was proudly boasting
100 watts, Yikes, I never use more than 20 watts and my signal makes it
no problem.

Hi,
OSCAR-11 is off at the present time. I'm expecting it to switch on
during Wednesday May 25th at about 05:17 UTC, when the satellite is out
of range for UK.
I would appreciate any reception reports for next Wednesday before and
after that time. It is equally important whether you are reporting heard
or NOT heard.
When the satellite last switched off, it happened during a pass over
UK, and I was able to get a precise time of switch off. Reports on
Wednesday will help me improve the accuracy of future predictions.
Please add your report to the satellite status web site URL

I agree that many people use too much power. But, remember it is not just
the output power that counts, it is also affected by the antenna gain. 10W
into a dipole is about the same in terms of effective radiated power as 1W
into a 12-13 dB gain Yagi.

Hello,
I want to thank the stations that called W2GSB/APM, airports are not the
most ideal location for transmitting with all the metal around us, attached

While we empathize on the bathrooms (being a major morning coffee drinker
myself), what we REALLY want to know is:
- did CAMSAT have anything realistic to say about HO-68 ?
- any new satellite radios announced by anyone ?
- I'll settle for ANY new radios announced by anyone ?

Dean,
Something else to consider is that the "old" bird swtiched modes in the
middle of the pass. I do not have any idea when it switches from Mode B
back to Mode A since I am not capable of operating Mode B.
However, I can speak to it switching from Mode A to Mode B in the middle of
a pass. I had that happen several times and even in the middle of a QSO. I
haven't been on mode A in several weeks due to a new job, but last known it
would switch from Mode A to Mode B around 2325z and seemed to be getting a
little later ever day.

Hi Peter,
Many thanks for the detailed update, it's helped with my own project
planning! Hopefully the postponement was just diaries getting to full,
and will happen soon, maybe in time for breaking news at the AMSAT-UK
Colloquium in late July ? :)
Good Luck, and fingers crossed for a launch closer to 2012 than 2018!

Content-Type: text/plain; charset=us-ascii
The AMSAT/TAPR banquet talk at Dayton was about Solar and emergency power
for Ham radio. In preparation, here are three ideas that amazed me that
might amaze you:
1) This week by googling solar panels, I found PRIME home solar (UL
approved) 220 Watt panels going for $1.39 per watt! (compare that to $6/w
contractor installed systems 2 years ago...)
2) Even if you want to use bargain panels and bargain micro-grid-tie
inverters, one way, is to pay a contractor to install the smallest fully
approved and electrical-permitted solar system you can buy. This gets you
fully legal, connected, grid-tied etc. Then add as many panels and
additional plug-in micro-grid inverters at your own DIY cost!
Just remember, to connect + to + in parallel, and + to - in series... and
just plug in the DIY microinverters to the wall outlet. (Note, the UL
approved microinverters should be connected to a standard 20 amp breaker in
your breaker box by a master electrician).
3) Amazing angles! No-longer does SOUTH matter!!!
I hope everyone here has had the fun of playing with the on-line PVWATTS for
computing annual solar ouput over any conceivable arrangement of azimuth and
elevation angles. I just compared a pure EAST/WEST facing roof to the
optimum South facing, just to see how bad it would be. AMAZING! Here is
the PVWATTS page:
http://rredc.nrel.gov/solar/calculators/PVWATTS/version1/
DRUM ROLL: A DUE EAST facing roof (with a 20 degree tilt) will produce 85%
of the annual power as the ideal tilted southern array. Amazing...
BUT!!! SO does the WEST side of the same house! So, unlike the southern
home that can only use HALF his roof for power*, the EAST/WEST facing
homeowner can generate 170% more power than the sourthern facing owner
because he has twice the room to put the panels!!! (Roof size and shade are
the #1 limits to homeowner 100% production of their annual electrical needs).
*But wait, there's more! Next for grins, I used PVWATTS to tell the power
output from the NORTH FACING side of the South Facing house. Who would ever
even think of doing this? But if the ROOF tilt is the typical low profile
20 degrees, guess what? The NORTH side of the roof can produce 60% (annual)
of the south side! So the homeowner with his low-profile southern roof
maxed out with solar, can now increase his total annual output by 60% (with
a double sized array (on a low tilt roof)). He produces nearly zero in the
middle of winter from that side, but makes up the full 60% of his total
capacity for that array in the summer!
Many hams who know that SOUTH IS BEST find it hard to accept this. But do
the PVWATTS calculations yourself. Remember, the SUN comes up in the NE and
sets in the NW during the summer when the days are 14 to 16 hours long.
This means that for the 3 hours in the morning and 3 hours in the evening,
the IDEAL Southern array is not even seeing the sun. Sure, an east facing
array will produce little in the winter, but for GRID-TIE, the ONLY thing
that matters is ANNUAL total power. and all these other directions make up
for their poor winter performance by making MORE power in the other months.
Even laying flat on the ground will produce 80% of the annual power (but be
a maintenance issue... Any panel should be at at least 10 degrees to assure
rain-cleaning).
Back to the EAST/WEST facing house... Doubling the array to get the added
160% may not have been cost effective in the past, but with DIY panels at
$1/watt and DIY plug-in micro-grid inverters at about $0.30/W, it's so cheap
to expand your array into less productive angles, why not! DIY panels and
added plug-in DIY microinverters can double the size of your "approved"
array for probably 1/4 the original cost of your contractor installed system.
Putting panels on EVERYTHING until you get to 100% of your annual electrical
load is the goal. You can do it! Look outside the "southern" box. (But
shade remains the #1 killer of even the greatest solar ambitions. But as
costs are so low, look again...)
Don't forget, the economics of homeowner solar is all due to GRID-TIE.
There is not a single battery in the system. Off-grid battery systems can
only deliver about 33% of annual energy for the same $ investment plus the
added burden of lifetime maintanance. GRID-TIE is the only way to go (if
you are on the grid)... Please see:
www.aprs.org/off-grid-maybe.html
Oh, and the BIGGEST FACTOR by far is the almost 50% Government Credits,
Rebates and Grants that come right off the top of your installation costs.
I would bet these are going to be gone in a year or two (my state has
already reduced theirs by 1/3rd), beacuse the cost of home-solar produced
power is now LESS than utility power (with the 50% incentives) and so
EVERYONE is jumping into solar. With tight budgets at all governmnet
levels, do not expect these incentives to last.
Next week, I'll post slides from the AMSAT/TAPR solar talk.
Oh, and please come join the SolarDIY@xxxxxxxxxxx.xxx discussion group made
up mostly of HAMS going solar.
