Gentlemen,
Most of the current cube sats and those to follow in the future all
use data communications for transmitting telementry back to earth.
In order to receive this data a ground station requires a TNC of some
sort that can work up to 9600 baud.
To those of you who are already using
Hi AMSATs,
I received the news that VO-52 will be switched on in a couple of hours from
now, at 13:50UTC, (03-March-2012)
Unfortunately the satellite will not pass over central Europe, and I am not
able to check the status the first two orbits.
I am looking for hams in Russia, Northern Europe,
Hi AMSATs,
There was a slip on my fingers.

Hi AMSATs,
I received the news that VO-52 will be switched on in a couple of hours from
now, at 13:50UTC, (03-March-2012)
I updated the keps and now when I open satpc32 I get a error message that
keep repeating and the only way to abort the error message is to reboot.
Removing the keep file does not fix the problem. Help??
Thank

I renamed the kep file and restarted satpc32 It then ask for a new file and
I pointed to the previous file that worked before. At this point as soon as
I say ok the program goes into a loop and I no longer have any control to do
anything. The only way out is a reboot. What do I do next??

Keith,
Sounds like you have a sat that is not longer in use in the Satellite sections
of SATPC32. Trying and delete the decommissioned bird in between hitting
the error icon. This has happened to me before.

Nick,
Did you happen to use the backup utility that comes with SatPC32?
That has saved me a number of times. I try to run it every couple of
weeks, when things are running smoothly.
Then, it's a restore from the same utility, to get things back to normal.
Otherwise, you'll have to try
Dave,
There are a lot of TNCs around which will do 9600. I have a DSP-2232 which
I used until recently. These days many are moving to using sound cards and
software, such as MixW and the AGW Packet Engine. Whatever approach you
take, remember that you need to use the rig connections for 9600
Backup fix it
Thanks Mark et all

Due to 'Operational Constraints' the commands to turn on the
transponder were not been able to send. In-convenience caused is
regretted.
The next attempt would be made during 01:44 UT pass over India.

Hi All,
I am going to host an AMSAT table at the RARSFEST in Raleigh, NC on
Saturday, April 7th (yes, Easter weekend).
Anybody care to assist? We usually can't pull off demos, but hosting
a table with toys+tracking programs usually draws some good attention
and publicity.

Here's a quick update on my G5500 Azimuth rotator story. (Recall that
three weeks ago I stalled the rotator after switching antennas.)
Yaesu Parts USA is still backordered on the replacement motors,
possibly some will arrive from Japan in a few more weeks (or possibly
not). The
Hi Mani, VU2WMY
I would like to know from you if the attempt to switch ON
the Dutch transponder on VO-52 at 01:44 UTC, March 14
2012 was succesfull or not.
Actually at 02:09 UTC and 07:39 local time over India there,
are no messages about on AMSAT-BB
By the way I will monitor the orbit 37091 at
Hi Dave,
How long does one have to stall the motor before the windings'
insulation starts to degrade? I seem to recall it's not very long (less
than minutes).
With all that thermal mass, and the insulation from the heat shrink
tubing, is the thermal switch really going to be effective
Hello Domenico,
Not attempted during 01:44 UT pass.
Probably the command station may give a try during the next pass at
03:20 UT. Not received any updates from them yet.
Will keep you all informed with the ongoing developments.

Hi!
I was outside for the 0245 UTC VO52 pass here in central
Arizona (DM43), and heard nothing from the transponder
or the CW beacon. That was a 74-degree pass here,
which should have been easy to copy.

Hi Greg KO6TH and Dave KB5WIA
I have always seen the thermal switches buried into the windings
themselves both for transformers and motors.
To prevent short circuits between turns of the windwing is better to
use # 24 fiber glass copper insulated wire for class H insulation of
motors or
Hi Greg,
Hey, thanks!
Good question about how long it takes the windings to degrade.
Haven't tested this myself, but I'd seen a post a while back where
someone measured current draw on the motor, and found that it's
actually almost the same between normal operation and a full stall.
That also
