I am working on a couple of projects lately. Working with discrete parts
was starting to get tedious so I decided to use a small micro controller
so that my parts count and wiring would be minimal.
If you are interested in working with small Microchip processors, this
is an easy and cheap way to start.go to the software page and download
the FREE PICAXE? Programming Editor Software (free download).
I bought a programmer board kit and qty 5 08M chips (Microchip 12F683)
for $38 shipped from a US distributor.
http://www.rev-ed.co.uk/picaxe/
You can begin programming and simulating even without the chips on hand.
Using the flow chart tool, I have created code for a model rocket beacon
and with help of my son a repeater controller accepting 4 COR inputs.
Multiplexing the COR inputs was stumping me until my son intervened.
Both of these projects simulate well with the above software. Soon I
will download to chips and try out on breadboard.

This is a moot point. In the VHF contests rovers are only allowed to
operate from one grid at a time. So if a rover is straddling grids, he
must chose one or the other to send as an exchange and move a
reasonable distance, I think 100 Meters, before the rover can operate
in another grid.
Rover operation in contests is more restrictive than other times, not
less. I rove and I know. - Duffey

I am a long time supporter of the ARRL. They needed, in my opinion, to give a
lot of notice to the changes to the standards being applied in the VUCC
program. Folks are taking time and spending money to put on rare grids and it
goes down the drain if they find out the rules changed. That is called
detrimental reliance. Please give a lot of NOTICE to changes. Folks act on
the rules that they have become accustomed to over long periods of time. Yes,
any operator needs to check the rules before they act. Changes need PUBLICITY
too. That did not occur here with the VUCC changes in this instance.

Jim and all,
I agree whole-heartedly. It's not so much that they changed the rules,
although I'm dumbfounded at the lengths they are going to in this case. As I
said in an earlier post, it's not like there are grid-border stations very
often.
The other thing we ARRL members should keep in mind is that - in a perfect
world - the leadership of the League is there to serve the membership. I am
really curious to know what prompted the changes. I and every other member
have a right to know.

As I read it...you were disappointed with the ARRL and not N3TL's
questioning. I too worked through Gus Browning and Don Miller...
If the league has a legitimate question...as in the intersections are in a
"lake" "ocean" or side of a "shear cliff" they should request documentation
from the "DXpeditioner" for some sort of proof...
GPS would be the ultimate, but 360 degrees of pictures from a camera could
be the standard. (Next they would want recordings to make sure there aren't
any "Ghost" contacts.)
ARRL is not capable of overseeing Satellite contacts and awards...they
really don't care about satellites...
VUCC satellite should be an AMSAT function so that those who understand the
hobby can judge the hobby!

Your conclusion about my prior comment (N3TL's post) is proper. It is the
League in whom I was disappointed . . . . . lack of publicity. . . . .
mainly.
Your comment that the League is not interested in satellite operations is,
in my opinion, also proper. I posted a few weeks ago here on the AMSAT BB
my "first impressions" . I had operated satellites in 1974-1976. Upon my
return in August 2008 I was shocked that I actually operated through 7
different satellites. There are some that I have not yet tried too. From my
reading of QST I had the inaccurate impression that there was one FM
repeater type and maybe a digital bird too. I am not the sharpest pencil in
the box but I am not alone in my inaccurate perception. I walked past
AMSAT'S booth at the Dayton Hamvention the past few years. It was not until
I was outside the convention building this year and saw a live demo that my
interest was again raised. I have invested in a couple of M Squared yagis,
an elevation rotor and a Ham M for my satellite operation. Then I upgraded
to an Icom 910H with almost every option but the 1296 mhz module. That is a
nice amount of change to throw into the satellite game. It works fairly well
and has provided me a great amount of enjoyment in my recent retirement.
I was disappointed that AMSAT and ARRL have not accurately publicized what
is available. I remember a column in QST some years ago. Nothing now days.
I might add that I normally look up those I work (so far 500 QSOs in 135
grids) on QRZ.COM. I see that more than one-third are old timers. I worked
one Old Timer who is well into his late nineties and several who are in
there nineties. The satellites need more publicity. I have found almost
everyone on the birds to be outgoing, friendly and courteous. I am enjoying
the birds. Thank you AMSAT and ARRL for their contributions. A better job
can be done to encourage satellite usage. I see there are those who are
attempting that. I hope I can make a contribution. I gathered a small group
of satellite users here in Cincinnati for lunch a week ago. We are helping
each other with issues (software, antennas etc). Ham Radio is a wonderful
hobby.

Hi Bruce,
Wow, I had no idea these existed. The price certainly makes them very
attractive, and it looks like some of the larger varieties have better I/O
capabilities too (SPI, I2C), though I suspect some of the newer Stamps
probably do too. I haven't poked around their site in a while.
My Az/El rotor controller uses the 24-pin Basic Stamp-II, which at ~$50
(still!) was easily the most expensive component in the whole project. But,
it works well, and I had a lot of fun working with it. That was my second
Stamp project (the first was a simple phone patch controller). See
http://home.wavecable.com/~ko6th, near the top of the page. Links to a brief
description of the rotor controller design and an old copy of the source code
are there in the upper left box.
I'm a software engineer and project manager by profession, but it's all with
embedded code - internals of operating systems, I/O drivers, protocol stacks,
and stuff like that. I missed the GUI revolution (or more precisely, pre-
dated it!), so my struggle right now is that I really want to write a nice
mouse-driven front-end for my Yaesu 736R satellite rig to usably handle
Doppler shift on the SSB/CW satellites, but I haven't figured out how to do it
yet. I have the FM birds fully automated, but the CLI-based program I wrote
for tracking frequency is horrible when you don't know before hand what
frequency you'll be on.
I have a book on "C++ GUI programming with QT3" for Linux, but haven't been
able to make much progress yet.... Next project, after finishing my GPS
module add-on for my Kenwood TH-D7...

Does anyone know if something has happened to NLSA?. I,ve emailed them about a

Hi group
A middle school teacher ask me how ham radio helps teach science and
geography. I hope some on the list would share a power point
presentation with us??
thanks
