AO-40 Transponder
The
uplink frequencies are 435.550-435.800 MHz and 1269.250 to
1269.500 MHz. The downlink passband is 2401.225-2401.475 MHz. The
transponders are inverting, so a downward change in uplink
frequency will result in an upward frequency shift in the
downlink.
ANS Principle Satellite Investigator N1JEZ was first to report
contacts on the AMSAT bulletin board. "Things are working
quite well," said Mike, "I've successfully logged a
dozen contacts in the first hour of operation including two
contacts using the Mode-L uplink. I also logged my first DX
contact with IZ8EDE. The comment I heard most often was how weak
the S-band downlink was for some stations. In these situations,
the natural tendency is to increase uplink power. Without the
benefit of the Leila system, I'm sure a few of us were running
too much uplink power, but, it will take a bit of time to get a
good feel for uplinks and downlinks. My final tally was
24-contacts including some DX. A great first day! Let's hope for
many more."
Ed, K9EK, echoed Mike's comments. "Wow, AO-40 was terrific
on this first morning of transponder operation, said K9EK,
"after almost 10 years, what a thrill! Heartfelt thanks to
all those who have busted their backends for so many years. You
are appreciated!"
Maggie,
K3XS, in all likelihood made the first YL contacts through AO-40
working KB8VAO, W5VZF, W4AD, WC0Y and N4IP. Pieter, N4IP,
reported signals at 51,000 km were about S-3 above the noise at
his QTH. Pieter worked I8CVS using the 70-cm uplink. Jerry, K5OE,
told ANS that KB8VAO and N1JEZ were among the best sounding
signals.
Roger, W3SZ, reported working a number of stations including
AB9V, KK2L, VE7BBG, G3WDG, K5QXJ, W7AM and others.
AMSAT-NA President Robin Haighton, VE3FRH, released the following
to ANS:
It was with great pleasure that I worked AO-40 early in the
morning of Saturday, May 5th. Signals were generally good. To
satellite enthusiasts there is nothing quite as exciting as
working a new bird, especially when we have all watched and
waited as AO-40 went through it's troubles and (now) is returning
to us as a great satellite. The very hard work that Project
Leader Karl Meinzer, AMSAT-DL President Peter Guelzow and the
worldwide supporting group of command stations and technical
individuals - is providing us with a great satellite. Thank you
all!
73,
Robin, VE3FRH

First contacts on AO-40
First SSTV Contact on AO-40
Hi
All,
This was an exciting day and it is believed
history was made for A0-40
in sending the 1st SSTV pictures thru this satellite!
Don Miller, W9NTP and Farrell Winder, W8ZCF of
the MAREX-NA group
succeeded in getting several good pictures through
AO-40. W8ZCF
transmitted on 70 cm and W9NTP received on 13 cm. Tests
started about 12:30
UTC on Saturday May 12, 2001 when the satellite was out about 48,
000 km and
continued until the satellite was at a range of 40,000 km.
Signals were not
strong and Don reported S readings of only 2 to 3. SSTV was sent
only one
way as W8ZCF did not have receive capability in place.
The experiment was 2 fold. W9NTP and
W8ZCF, along with others of the
Marex group have been developing and testing the NEW SSTV System
for the
International Space Station. It is called SpaceCam1. All
pictures during
this phase of the test were sent via SpaceCam1 using R36 and S1
modes.
W9NTP and W8ZCF were believed to have received
the last 2 pictures from
AO-13 the day before its re-entry into the earth's atmosphere as
reported
in an article in CQ VHF February 1997. It was planned at
that time that a
try would be made for the 1st pictures via P3D ( now A0-40)
and it is
believed that success and history were made today!
Also an unusual record may have been set
in that 2 meter terrestrial
contact (about 80 miles) was later maintained in experiments
between W9NTP
& W8ZCF while W8ZCF transmitted voice on 70 cm
via A0-40 to W9NTP listening on 13 cm..
For details of SpaceCam1 see:
http://www/marex-na.org
It is planned to within the next 24 hours to
have some of the received
pictures via AO-40 on this web site.
It is hoped that others will follow with SSTV
via A0-40. This satellite
is performing in excellent fashion, under the
circumstances, thanks to the
perserverance of the many who built, tested and have
recently worked so
hard in getting optium performance of AO-40.

: AO-40 in good shape
Path: !ON0OB!ON0CK!GB7SXE!GB7JYU!
From: G8VR@GB7JYU.#34.GBR.EU
To : AMSAT@WWW This morning, Sunday May 13th, the AO-40
beacon and transponder were working
very well and the beacon particularly stronger than I had heard
it previously.
I worked ( on CW) ZS6JT, W3SZ, W4NUS, AC9R, OK1AQK, LZ1DP, LZ1JH
and I7LIT.
Also a QSO with G3WDG using LSB , Charlie using CW. I
used the 435 MHz
uplink with 30 watts to a 19 element horizontally polarized yagi.
For the 2401 MHz downlink, a 16 turn home-brew helix of the G3RUH
design, into a Downeast microwave converter preceded by a MGF
1302 pre-amp. It was a long wait, but
worth it. Let's hope further recovery of this satellite's
facilities is
possible, but meanwhile it's great to have this new bird.

!ON0OB!ON0CK!GB7SXE!GB7JYU!
From: G8VR@GB7JYU.#34.GBR.EU
To : AMSAT@WWW Following my morning session with
AO-40 on May 13th I decided to stay up
late and catch the satellite as it came up over horizon here (
22.30 UTC May 13th). Immediately the beacon was heard at
good strength. The S-Band downlink was mainly deserted
apart from two Japanese stations , JA1JRZ and JR1ASH,
both of whom were easy to work on cw. The 435 MHz
receiver on the ssatellite seems to be extremely sensitive since
my uplink erp is quite small. The S-band downlink is strong
enough using my tiny 16-turn helix , so all in all
this satelliote is very easy to access with simple
equipment.There are
three or four kits available for 2400 MHz downconverters which
are not
difficult to put together. A small helix can be made out of
a length of
stout copper wire and ( in my case) supported by a short
length of 1" x 1"
timber. By mounting the 2400 MHz bits at masthead with the helix,
the
co-axial feeder bringing down the 145 MHz IF signal need not be
low-loss
and I use about 45 feet of RG58.
6 countries in 4 continents at my first attempt to access this
bird! If this old
codger can do it, so can you, and it's a lot of fun.
Cheers, Ken G8VR
TELEMETRY
The modulation format used by the satellite is quite simple: it's a 400 BPSK Manchester-encoded transmission, frame oriented, no FEC, CRC certified, containing 512 bytes of ASCII and binary data. Total troughput is 200 bits/s.
Hello
All,
Here is the telemetry I receive on sat 2 dec 2000 at 17:09 UTC on
VHF.
I stripped the logfile to readable text only. Data is displayed
seperatly further below.

K AMSAT OSCAR 40 **STATUS REPORT FROM DJ4ZC** (2000-11-20)
1. AMSAT OSCAR 40 had a perfect launch on Nov. 16 and was
injected into a nominal orbit.
2. Transmission of telemetry from OSCAR 40 on 70cm was expected
3h after launch. But we ran into a problem with the 70cm
Tx. Consequently the spacecraft was switched to use the 2m
middle beacon as downlink for telemetry. This required a
"repeater program" in IHU-2 which was uploaded.

L 3. After communication was established, the health of
OSCAR 40 was analysed and everything testable at this stage
except for the 70cm Tx was found to be nominal and fine.
4. The attitude control system then was calibrated and torque
operations were started to take the attitude to 270/0. This
reorientation should be finished in a few days. Then we are
ready for the first planned orbit change (400N-mtr) resulting
in 50000 km apogee altitude. The attitude will also allow a...

K AMSAT OSCAR 40 **STATUS REPORT FROM DJ4ZC** (2000-11-20)
1. AMSAT OSCAR 40 had a perfect launch on Nov. 16 and was
injected into a nominal orbit.
2. Transmission of telemetry from OSCAR 40 on 70cm was expected
3h after launch. But we ran into a problem with the 70cm
Tx. Consequently the spacecraft was switched to use the 2m
middle beacon as downlink for telemetry. This required a
"repeater program" in IHU-2 which was uploaded.
