Kevin,
if you have an iPhone or iPod/Pad, try an app called "Maidenhead" it's free
and will convert your position (if Wifi or Internet enabled) to a grid
locator. if your not connected you can still enter the coordinates manually
and get the results.
Also www.aprs.fi will show the grid location of the cursor in the map screen.
Finally, pretty much all GPS units will show coordinates in maidenhead. My
Garmin Etrex Hcx, will do it. all you need to do is select Maiden head in
the preferences for coordinates systems. In fact I can select the
coordinate field twice on the display, once showing lat/>long the other
showing the grid. One caveat. if you are on the boundary, the grid display
will show only one grid, not both. But again with the lat Long display on
the same screen, there should be no doubt as to you position on the boundary.

That's what I'm using. I tried them all, and ended up with Gpredict as my
personal favorite. It was however not based on
the pure fact that it was open source but simply that it fits my working
style best. The fact that it's code is open and I can
contribute to it, is a big benefit.

Not that many because it's like you said not an easy thing to do but also
it's not something where you can address a huge user base.

Because maybe they have invested years of their time into it, and don't want
to see it all hacked up beyond recognition by the whims of a few hack-and-go
programmers who play with it for a while, screw it all up and then move on
to the fad of the next flashing icons

And what has that to do with Open Source software? Let's assume Simon
would've opened the code
and other's would've been able to contribute. Out of the gate you already
assume that everybody else
writes bad code. That's simply BS. Moving on .. if code is opened, it's not
like everybody just hacks away
beyond recognition but maybe makes a useful contribution which that person
then would have to
check in upstream to Simon so that he could include it into the main source
tree. After all, the official
version of OSS HRD would still come from Simon just with more people being
able to contribute.
When I read some of the statements here, it seems that there's a huge
misunderstanding of Open Source
software and how Open Source communities and software development works.
Sure, people could use the code and fork it and "hack it up beyond
recognition" but who would use that?
Also it would be a fork and history has shown that most forks that were not
in line with the mainstream source
tree were not long lived.
Another reason of course for not open sourcing one's code can be that the
code is so bad that one doesn't
want to invite criticism (and this is not pointed at Simon, as I don't know
his code, rather a general statement).
There are plenty reasons for not opening code and plenty more for doing so.
But nobody should be forced in
either direction. I don't believe we (open source pro folks) can on one end
preach freedom and then on the other
try to force it on others.
Would it have been great if Simon would've open sourced HRD so that for
example people could've ported it to
other platforms? Well most certainly yes. But he decided not to, and that's
a decision we all have to respect.
After all, if you don't like it, don't use it. There are alternatives to
almost everything.

I have to say the statement about people not having the experience, time and
patience to maintain it is pure egotistical nonsense. Plus it completely
misunderstands the idea of maintainers of the source tree. Open source code
is always better because no matter how clever ones thinks they are as a
programmer, there are always better coders. If HRD was open sourced, I
guarantee the satellite tracking piece would work perfectly for all radios
because we would have fixed it.

You clearly don't understand open source. Is the Apache http server "hacked
up beyond recognition"? I suspect hams keeping their source closed is far
more about ego than the sanctity of the code base.
As someone else said though, I respect any authors decision to keep their
source closed. It is their IP. I just don't agree with it.

And why would you care if they do? It doesn't make the program work any
less. You are under no obligation to accept their patches back into your
source.
Let me turn my question around, then. What do you gain from keeping your
source code a secret?

I've been wondering if anyone besides me has tried to hear themselves
using an Arrow or Elk antenna via ARISSat's linear transponder.
If you have tried it and successfully heard yourself, please let me
know. I'm curious as to what was your formula for success. The rig
I've been using is an FT-847 and for an antenna either my Elk or Arrow
mounted to a camera tripod.
I've made about six attempts now on passes that I thought were very
favorable to success. I've had zero trouble receiving telemetry or
SSTV during these passes so I'm sure the bird was actually overhead
during my attempts.
I'm not ready to give up but time is running out.
