>> ... The small piece of paper that my proposal outputs is a single
piece of paper with about 10 numbers on it, no bigger than about

In my AMSAT presentations, I show both graphical representations of
sat passes, as well as pure numeric data. My audiences much prefer the
graphical representations. So, what you are requesting may not have a
"market share" as great as you might think.
This reminds me of the old Internet wives tale about the development
of the space pen. You remember ... The story goes that America spent
millions of bucks to develop a writing implement suitable for space
travel. But what did the thrifty Russians do? Used pencils ...
It is not a true story, of course: Both manned space programs used
pencils at the beginning of their projects. But it makes a good Cold
War story for the U.S.
ANYWAY - There are several online (and FREE) sources for the info you
seek ... as well as commercial programs that will generate the info.
Want to slap something on your visor? Geeze, just write it out ... or
cut and paste ....

Is that your usual way of of asking for info?
seems a little strange you assume info comes from that high
mostly i was googling , I believe tokyo ham fairs few months ago
or something while really looking for info on the new 9100
and noticed it by accident
I noticed a picture and paragraph on it, i am sure if I found it
anyone could

Putting together a USB 16F877 rotator control A/D serial and LOGIC
Got a few options
Predict as the AZ/EL engine and perl scripts.
1. Completely autonomous - quite hard to do in a PIC
2. Use the A/D and just send data back to LINUX and get LINUX to turn relays
on / off via parra port
3. Send AZ and EL to the PIC, do a ASCII to BIN and then get the PIC to
drive the rotators.
4. Use the A/D and send data to LINUX and then send back a serial command on
what to do.
Cheers

Quite a lot of guys are using the handy Arrow Model 10W
duplexer for the handheld 146/437 antenna and mine arrived here
today so I thought I would put it on the network analyser
and see how it performs.....

Never did get it to work properly in the program itself
However, someone off the list sent me a link to his own software ( very nice
software )
For controlling the rotor and it also ties into SATPC32, Orbitron, and NOVA.
( plus some others )
So all is well and its going great now..
Thanks for the replys..

I'm grateful to everyone who has contributed to this discussion.
It strikes me that the greatest improvement we could make to hand-held
yagis would be to somehow integrate a low noise preamp circuit very
close to the 70cm port. I have an indoor-style ARR preamp that I've
thought of connecting to the boom with cable ties. A powersupply using
AA batteries and a DC to DC buck-boost chip from, e.g., Maxim, would
keep the whole thing light. (Alternatively, I see that the max voltage
for my ARR is pretty high: I might get away with a pair of Nicad '9v'
batteries.)
Like so much of amateur radio, it's more of a challenge of
construction than anything else.
Has anyone experimented with this sort of improvement?

What would be neat is a survey of how many other locations are
doing this. One way to do it is to watch the APRS-IS for AO51
objects and see where they are coming from. Of course, they
will all overwrite and replace each other, but if one monitors
over a reasonable period, then we might see each such system in
turn when the AO51 is overhead.
Would you have time to watch the APRS-IS and see if you can find
other systems doing this? Then we can make a MAP of the world
where this information is available and encourage others to
consider putting it out.
Thanks

There has been some discussion on how to determine
when a bird will be in view over an extended period
of time. You really don't need a pocket computer
or laptop to carry around to do this. Just simply
print out the pass predictions using SatPC32 sold by
AMSAT and written by DK1TB who has donated the program
to AMSAT.
There are two accessory programs included in SatPC32.
The first is called WinAOS and it will make predictions
for multiple birds of your choosing over a 10+ day period
of your choosing. Print out the results and keep them in
your vehicle. You'll have AOS/LOS times and AOS/LOS azimuths
plus max elevation and visible time. This is plenty of info
to allow you to work a bird with a handheld antenna. Just
watch the time and move the antenna accordingly.

The other program that comes with SatPC32 is WinListen. This
program will give you satellite visibility at various intervals
throughout the pass. It has a two-observer feature which allows
you to enter two grids and find the mutual window on a particular
satellite. Here's an example between Ohio and Scotland on AO-51
at 20 second intervals.

is remote.
These two programs are selected under the "Programs" link in the

Thanks John for the info.....never had really looked at that before, as I've
always used the Orbitron printout. Only thing on the SatPC32 printout is
wish the print was abit bigger for us old guys, and abit darker, but
otherwise it has good info......tnx again...

Hello All,
Looking back, the "Road Trip to FN56, FN57, FN66, FN67, etc." was
eminently successful. In the course of two days, I drove 1,119 miles
from my Dad's home in Massachusetts to Maine and back: 429 miles up,
261 miles around the back woods of northern Maine searching for
better-than-average operating locations, and 429 miles back.
In the process, I activated every grid square north of Bangor, with the
exception of FN45, plus I activated FN53 in southern Maine as well. Put
another way, I worked 11 satellite passes to activate 7 rare grid
squares in two days. In that time, I would estimate that I made over a
hundred satellite contacts.
My appreciation goes out to all who participated.
If you're interested in the actual locations I worked from, it's
summarized in the chart below in the order that I worked from them. The
latitudes and longitudes were recorded on site from a Garmin "GPS
12XL", except as noted.
=============================================
Actual Locations for Saturday, October 17th:
# Lat Lon Grid Nearest Town
-- ------- ------- ---- ----------------
1 43.979N 69.978W FN53 Topsham, ME
2 45.596N 68.535W FN55 Medway, ME
3 46.791N 68.040W FN56 Caribou, ME
4 47.006N 68.180W FN57 Stockholm, ME
5 46.854N 67.988W FN66 Caribou, ME
=============================================
Actual Locations for Sunday, October 18th:
# Lat Lon Grid Nearest Town
-- ------- ------- ---- ----------------
6 47.132N 67.954W FN67 Van Buren, ME
7 47.132N 67.954W FN67 Van Buren, ME
8 47.006N 68.180W FN57 Stockholm, ME
9 46.854N 67.989W FN66 Caribou, ME
10 46.692N* 68.015W* FN56 Presque Isle, ME
11 45.988N 67.862W FN65 North Amity, ME
=============================================
* At the time, I was so busy driving from one operating location to
another that I didn't have time to record the latitude and longitude
from the "GPS 12XL". So, it was determined later from topographic maps.
=============================================
You probably won't hear me on the satellites for a while. Instead, I'll
be focused on completing several antenna related projects before winter
sets in. Among other things, I need to get my outdoor satellite
antennas back in operation.
But in the mean time, send me your list of other rare grid squares you
need in the northeast USA. I'll consider traveling to and activating
any grid square in NY, PA, CT, RI, MA, VT, NH, and ME.
With winter approaching, this probably won't happen any time soon. But
when the weather breaks next spring, the opportunity for doing this may
come again. The most requested grid squares will be the ones I consider
going to first.
So, email me your grid square "wish list". And please put the phrase
"grid square" somewhere on your email "subject line".
73,
Richard, N2SPI

Last winter I temporarily set up a 2m 1/4 WL ground plane with 432
preamp (similar to the ARR) and powered it with a single 9v
"transistor" battery.
Most of the Gasfets use regulators to lower 12v to a usable working
voltage. Or for a long-term solution series two 9v batteries and add
a LM7812 regulator. Simplest wx-tight enclosure for an ARR preamp is
a small zip-lock bag. All small enough for hand-held Arrow setup.

BTW interested if Kenwood will come out with an upgrade for the TH7-G
(had one and was great little radio)
