Was AO-51 transmitting last pass over the US? A direct, rapid reply
would be wonderful. There are reports of it not being heard on David
Carr's page, but that is common when at low power or S is on.

Thanks to Bruce and Carm for confirming it is running fine.

Just tried AO-51 L/SU.? The S band signal is weaker than it has ever been.?
Or my old AO-40 (sobsob) S band rx setup is maybe failing.? I was trying for
"stereo" reception on uhf and S band.? I did work KC9ELU just at his LOS.? I
had a fairly high elevation, anyone else notice this S band signal?? Maybe I
need a bigger dish.

Hi!
I will be at the Kingman Hamfest in northwestern Arizona on Saturday,
6 November 2010. This is a two-day event, but I will not be there for
day one on Friday (5 November). During Saturday, I will be there with
an AMSAT table and on the satellites as WD9EWK for demonstrations using
FM and SSB. This hamfest is supposed to run all day on Saturday, and -
if there are crowds there all day - I will be there. The hamfest is
in grid DM25xf, not far from the DM25/DM35 grid boundary in another
part of Kingman.
Depending on when the hamfest wraps up, there may be a possibility of
post-hamfest satellite activity from either the DM25/DM35 grid boundary
or maybe a quick drive over the new bridge near Hoover Dam from somewhere
in southern Nevada. One way to figure out where I will be operating from
is with APRS:
http://aprs.fi/wd9ewk-7
This will be a quick trip, and I plan on returning home late Saturday
evening. Before heading home, I hope to be on passes in the evening.
Possibly for SO-50 passes, and maybe as late as SO-67 and/or VO-52
passes. Since APRS coverage is pretty good in much of Arizona, the
aprs.fi link above should be the best guide to my whereabouts for those
passes.
For anyone working WD9EWK at the hamfest or anywhere else after the
hamfest, there is no need to first mail me a QSL request or SASE.
Please e-mail me directly with the QSO details. If you are in the
log, I will send you a QSL card (or cards).
73!

Have you looked at the Fox Delta stuff? I have one of their all in one tiny
box devices, that does APRS (Modem Built in) beacon and receive. All you
add is a radio of some sort.
Only thing I warn you of, is that it would be FOB India, so shipping times
are a little extreme. I think I waited about 3 weeks for mine to show up,
but I also ordered one that had already been built. I've been very pleased
with mine. Here's the link..

Hello AMSATs,
Work and home situation kept me away from having any ham time. But recently I
had some time to continue with upgrading my LE005 transponder design with a
PC104
connector (or is it PCI-104 ?), and some other features ;-)
The PC104 is a good choice for having a standarized inter connection system on
CubeSat projects. However, I seen some deviation in the placement standard of
this PC104 connector.
>From the following website I read:
http://www.cubesatkit.com/content/electronics/bus.html
"The CubeSat Kit Bus utilizes the same physical connectors as the
industry-proven
PC/104 bus, but in an alternate physical location so as to avoid unintentional
damage to PC/104 or CubeSat Kit modules."
With my focus on: "...in an alternate physical location..."
I would like to know what this possition is, and if this is now "the golden
standard"
in CubeSat world ?
My next worry will be the pin configurations. Is there any standard for
CubeSat
boards ?
Next I would like to know how modules are controlled by the data bus.
Is it like separate pins for PTT, TX, RX etc...
Or with more smart communication with lines like: address bus, data bus,
Clock,
Interrupt lines etc. (similar to old ISA PC cards)
Or maybe with I2C.
I keep it to these questions for now...
Next questions will follow out of the answers hihi...

William,
I'm afraid there is no "golden standard." CAPE-1 used the PC104 connectors
also, but they were placed for convenience not by any standard. I believe
CAPE-2 is moving away from these in favor of a backplane design and I'm not
sure what other CubeSat programs are doing.

Next I would like to know how modules are controlled by the out. The data sheet will tell you which pins are used for
which function, but I dont recall seeing a diagram showing the position of
the connectors relative to the mounting holes etc.
My effort at a simple cubesat board based on the Clydespace EPS pinout is
at: _http://funcube.org.uk/WP3/?page_id=195_
(http://funcube.org.uk/WP3/?page_id=195)
As you can see, there are plenty of free pins !!
