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

Robin reported working N1JEZ, WL7BQM, KB8VAO, VE3NPC, W5ACM, W3PM, W0OQC, W4AD, W4SM, K9EK, KB2WQM, KA0YOS, W3HH, AC9R and VE3BCG.

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.

Message from G8VR about his first contact on AO-40:

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.

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...

and will shortly be available on our website. There we will
also show the test-schedule for some first amateur operations.
7. Steps after 1st orbit change: test the electric propulsion
system and then use it to further increase appogee altitude

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.
