Is that page under active maintenance? It's a great resource and it
would make sense to keep it updated.

I'm not sure how often David updates that page. Keep in mind it's not an
AMSAT hosted or maintained page. I use it often myself, and wouldn't mind
helping to update some of the links to the newer ones. I think there are a
few newer cubesats that might ought to be added too.
The older AMSAT pages are from the previous version of the website, which is
kept available for reference and other reasons. Rick did recently tag the
outdated sat status pages so Google would skip over them. Perhaps it's time
to archive them out of plain sight.

Have a G-5500 and suddenly the rotor stops moving clock-wise past 180. I
stood under it and it makes no particular noises at that point, just stops
perfectly at 180. Was working the day before and flawlessly for the last 4
years.
It stops so quietly, it almost sounds like the limit switch or the
controller is stopping the motor. The elevation works perfectly and the
rotation works fine from zero to 180. If it were a bad gear or something
like that, I would expect it to grind or make some funny sounds
It is a royal pain to take the thing down; any ideas on debugging without
taking the thing down?

I cannot evaluate this, however, mine stops at 180 clockwise or
counterclockwise. You must have put it up with 180 as the
middle of the rotation. Make sure none of your cables have become loose
and is preventing this from turning. Insure that 0 degrees is still
correctly pointing
as I've seen the lower unit slip on the pipe (if it is installed this
way) from loose bolts.
Good luck and let us know what you do find as the problem.

Assuming this is a USB device that provides a "COM Port" serial connector,
then you should get some sort of reaction from Windows. If it's totally
inert, then my guess is that the device is broken, or the USB port on the
computer is not active.
I'd check to see that another device works in that USB port, just to validate
the computer side of things, and then maybe try the suspect device on another
machine. Again, Windows should react to its presence, if only to flash up one
of those annoying task bar bubbles. Did you check in the Device Manager to be
sure that it didn't sneak in unannounced?

The only issue I have ever had with a USB to Serial converter is latency.
I was programming a device which expected an instant response.
I used a tradituional UART serial port no probs.
Programmers need to be aware of this.
The device has to convert and there is a delay.
Just be aware of that

Thanks all for the responses to this. I was able to find a cheap unit in a
local electronics store that they agreeded to allow me to return if it did not
work.
While at first it appeared that it had the FTDI chip set (some of the driver
software referrs to that chip set..) it seems that it is a "Simple Perfection"
PL 2303 unit that uses a different chip set.
So far it works with all my equipment (inlcuding my FT 736 and SAT32PC) If
it does not work out in the future I will obtain one of the ones you have
mentioned.
Best regards and 73

The FTDI chip set seems to be the best way to go. I bought my adapters
through Parallax, for $14.95 plus s/h. I have found nothing that doesn't
work with it, either under XP or Vista.

Mark,
Keyspans are good. I have only one, really old, obscure piece of software
which won't work with them.
I got a rig programmer from RT Systems, and picked up one of the RTS-03 as
they guaranteed it would work. It did, and with everything else I tried it.
Somewhat brand X, but it uses the FTDI chip set.
http://www.rtsystemsinc.com/othercables_template.cfm?cfid=3106444&cftoken=39
931273
Something to consider is an adapter by Parallax. Go to WWW.PARALLAX.COM and
put in the part number 28030. It uses the FTDI chip set, and is designed to
be used as a programming controller rather than just a communications
interface, so it brings out a few more lines than does the typical USB to
serial converter. Some rigs may need those. With the USB A to mini USB B
cable it is about $20. I have never found a rig or similar control function
it will not support, even when making house calls. The only drawback it
that it doesn't really have a case. With a little Exacto knife work you can
modify a cheap plastic RS shell to fit.

When I bought one for work to use with serial
port devices (Motorola RIB programing
interface). I had to reassign the port address
to com-1 or com-2 for the accessory to talk to
the application program. I think on my
particular computer the USB adapter defaulted to
something like com-7 or higher. I think I had to
reboot the application for it to stick. You
should have seen a new hardware alert when you
start up yoru computer the first time.

Happy New Year, everyone...
Last night's Straight Key Night was fun! I was pretty impressed with the
amount of stations on the linear satellites participating in the event.
Worked a few, missed a few, but still enjoyable all night.

Yes, lots of stations heard on AO-51 SSB/CW -> FM side. Though I'd try to
participate, but my CW is pretty rusty. It was really hard to copy the CW of
stations (including my own) which are under computer control, as the CW tone
kept jumping with the periodic Doppler corrections. Late in the pass things
settled down (fewer Doppler corrections needed), and that made things easier.
I'm pretty sure I heard WA8SME in there, but couldn't compose myself to answer
in a coherent fashion (I think I just sent 'de' and my call back), and then
the pass was over. Mark, was that you?

To differentiate between a stuck gear or the limit switch (or similar), can
you measure the drive current going to the rotor? If it goes up at the 180
mark, it's a jam; if it goes to zero, it's the limit switch.
Also, what does the controller's meter indicate? Maybe it's shutting it down
for some reason.

Hi Greg,
Actually you need to measure the current while it is moving, then if it
drops a little then its a jam, if it goes to zero then
its the limit switch.
I know this goes against reasoning, you expect a locked motor to pull more
current, but these are split winding AC motors with a
capacitor and they act differently.
This is also why when you get a cable snag you burn up the motor or the
transformer or both before you blow the fuse, that fuse I
think just saves you from a mis-wired or shorted cable.

The "easiest" answer is to set your receiver on 145.825 and wait for ISS or
PCSAT to pass by...
ISS is currently tasked otherwise and PCSAT is only partially usable in
daylight, but they both will give you the "easiest" reception in the next
couple of weeks...
Turn your PASSALL ON for PCSAT as it is only sending partial packets (longer
story) and open your received buffer to record daily activity and check it
when you get a chance...
UNPROTO is the best way to use these two "easysats" in packet mode.
As for transmitting...see how well you hear them and what their schedule is
first...
Happy New Year!

Ha, really... Thanks, I was "sure" it was the other way around.
So, if the current drops a little on a jam, why would it burn up either the
transformer or motor?
