Official LUSAT-1 Status Report
On june 1st 1994, during the 22739th orbit, the CW beacon was turned ON=
. This
operation was done by the control station (Norberto Pennini, LU8DYF) an=
d the
station encharged of the CW beacon (Rub=82n Ferreiro, LU6DYD).
Norberto (LU8DYF), turned OFF the "B" transmitter (437.125 MHz) and tur=
ned ON
the "A" transmitter (437.150 MHz). While this procedure took place, Rub=
=82n
captured some telemetry. When Norberto swapped the transmitters, Rub=82=
n started
to send the PN sequence, encharged to turn ON the CW beacon. After more=
than 9
months, the CW beacon was started again.
On june 2nd 1994, during the 22754th orbit, the CW beacon was turned OF=
F. This
operation was done by Norberto and Rub=82n.
Rub=82n turned OFF the CW beacon and Norberto swapped again the two tra=
nsmitters.
Once again, the CW beacon is OFF and the "B" Raised Cosine PSK transmit=
ter
(437.125 MHz) is ON.
We encourage those stations that have telemetry reports for this period=
to send
them to us for analisys purposes.
Overseas stations: If you capture any LUSAT-1 telemetry and send it in =
raw-mode
to the satellite control station, you'll receive a certificate for your
collaboration. These telemetry reports can be sent either via packet ra=
dio to
LU8DYF@LU8DYF.BA.ARG.SOAM and LU8DYF@ANY-ACTIVE-SATELLITE, or via Inter=
net to:
lu8dyf@asarin.org.ar
If you intend to use the satellite, please remember that the BBS is NOT=
LOADED
and it will NOT be operational for the next 2 weeks (approx.).
The LUSAT-1 recovery team want to thanks all the stations that sent LUS=
AT-1
telemetry data in RAW format.
The overseas stations that are going to receive the Special Award are:
1) Mr. Norimasa Okamoto (JN2LHU) from Gamagori city, Japan.
2) Mr. Bent Bagger (OZ6BL+OZ7SAT) from Denmark.

Hi!
I need the latest NORAD Keplerian elements and I don't know where I can get
them. If you know where, please forward me that information. Also, if you
have an "almost-new" NORAD set, please send it to me.
Thankyou in advance & 73's de Eduardo Sweet Biro (LUSAT-1 recovery team)

To follow up what I said yesterday about M^2 antennas and my problem
with SWR on my new Mode B setup:
> ... Also, I have an SWR problem, which I *THINK* is
> related to some inherited Belden 9913 and not the antennas...
It was, in fact, the cable. I replaced the feeds with brand new 9913
equivalent, and the SWR problem went away. Well, I did have to tweak
the position of the shorting blocks on the 2m array for best SWR, but
that was my assembly error, not the antenna.

Just my opinion...save your money and buy a better quality antenna
like KLM or M^2. I can almost guarantee you won't be happy with
the Cushcraft and end up buying something else anyway. The satellite
antennas are not their best product by any means, and besides so-so
performance, they may blow apart in the first good wind storm.

I started out with this setup, and I don't recomend it. The two
antennas don't point to the same boresight (patterns aren't
symmetric with the booms), and SWR rises significantly when they
are wet, even from heavy dew. I made a bunch of contacts using
this setup, but switching to KLM antennas made a world of difference.
I'm using the 22C and 40CX now, and am much happier.
