Eduardo,
Here is some info I've dug up.
2SC2290 was manufactured by Toshiba link
http://www.toshiba.com/taec/components2/Datasheet_Sync//63/21686.pdf
2SC3240 was manufactured by Mitsubishi
Turns out that 2SC2290A, SD1487 AND MRF454 are good replacements for
2SC2290.
MRF454 is manufactured by MA-COM.
RF Parts http://rfparts.com/transistors.html
shows both 2SC2290A and MRF454 as available.
I did not find any information on the 2SC3240 but there might be a close
replacement on the RF Parts site.
Regards,
Jarek, KB9IIZ
----------------------
Hello dears freinds :
I write to you to ask for a big favor. I own an old YAESU FT-747 which
final
RF
power transistors 2SC2290 or 2SC3240 were damaged.
I have not been able to find them, allthough I have searched ansiously.
A friend of my city gives myself two trasistores of low power and alone
I
can
to transmit with 45 watt in these moments
I need you to help me, for that Radio is my unique HF Station.
If you could help me find the two transistors I would be profoundly
thankfull.
Best regards for you and your family.

Hi Alan,
Well I have just had a pass over ZL with only one other station on and the
performance was quite interesting and repeatable. When the transponder is
triggered it stays on and does not drop out. Once the transponder is
released it has a few seconds of tail. Every attempt to retrigger the
transponder during the tail resulted in a drop-out of two or three seconds.
If you wait until the tail drops out it will retrigger as normal and hold in
without a problem.
In other words if I drop my carrier the transponder seems to enter its "tail
mode". If the second station begins transmitting within this tail the
transponder ignores that signal and still drops out. If the second station
waits for the tail to drop and then starts transmitting the transponder
holds in without drop-out.

Thanks John,
It would be very interesting to hear from other parts of the world where
only 1-2 stations are on whether the dropouts are similar. That would help
clarify the situation. SO-50 has similar dropouts, and AO-51 did as well
when the PL access was enabled.

The central USA pass was much like the eastern pass.
Signals from the satellite were very strong. Audio
was very loud, even on the wideband rx setting on the
TS2000. Audio cut off after a few seconds of transmission
was prevalent. It seems that it took several seconds for
the audio to come back when this happened. Lots of stations
on the bird including KC8ZFN, KD8CAO, WB8OTH, WC7V, WA4NVM,
KB1RVT, WA4SCA, KB0RZD, N5AFV, WD9EWK, N5UXT, WB2IOL, KF9L,
AA5PK and others. The bird went over the horizon before it
turned off.

Hi Glenn!
Nice to work you on that last SO-67 pass this morning. It was an
easier pass to get into from DM33xp/DM43ap here in Phoenix
(maximum elevation 40 degrees) compared to the earlier pass
(maximum elevation 8 degrees).
I posted my two MP3 recordings from this morning, along with the
MP3s from the two SO-67 passes I was on last weekend, at:
http://so67.wd9ewk.net/
The URL was just set up, so it may not respond for a few hours until
the DNS change propagates. I also posted PDFs with the passes at
those times there, so you can see how things looked from here in
Phoenix.
Following the advice about reducing mic gain and narrow FM helps in
getting through. On the second SO-67 pass this morning, I went one
step further - I held my mic about 8 inches/20cm below my mouth
while transmitting. Doing that, and following the other hints, allowed
me to have a transmission of more than 2 or 3 seconds get through
SO-67 without dropping out. I have been using an IC-2820H with an
Elk Antennas handheld 2m/70cm log periodic when I have worked
SO-67.
It would be interesting to see how this satellite worked with no PL
required on the uplink, since it is only being activated for 13 or 15
minutes at a time. The PL doesn't appear to be needed as a tool
for power conservation, as on SO-50. Does anyone know if it is
even possible for the SO-67 transponder to operate without that
PL?
73!

Have just completed a second pass this morning over VK/ZL and this confirms
the previous observations(seven or eight stations on). Waiting for the
transponder tail out before transmitting shows no dropouts. Any
transmissions started within the tail dropped out when the tail dropped out.

Hi, Pat.
I agree. Narrow FM and reduced mic gain is the way to go. You came through
fine.
Listened to your recordings and John's from earlier. Thanks for posting
them.
Once the bird is commissioned and the drop out issue is resolved, this will
be a great addition to the constellation!

AO-7 just finished her first pass over North America as a 35-year-old. She
is in Mode A tonight, and appears to be working well. I called CQ in CW for
about 10 minutes, and one station tried to answer me.
That operator sent the letters F and I in CW, but there were long tones,
too, that suggested some kind of keying problem. If you are that operator,
you were a solid 579 into EM84, and I was using an end-fed longwire not very
high up as my receive antenna on the 10 meter downlink.
AO-7 should switch over to Mode B in about 4 hours. I hope to hear many
folks celebrating her 160,000+ orbits of service to the amateur satellite
community beginning in the morning.
73 to all, and Happy 35th to AO-7,

Aloha All
On the 0226Z AO51 pass today, I attempted
to xmit QRP SSTV (2.5 W) to WH6BIE
5000 miles round trip back to Hawaii (4 deg
max. el)
Surprisingly, prior to my SSTV xmit, I picked
up several new stations but as my digital recorder
was in the xmit position and my hands full with my
Arrow, HT, and digital recorder I was unable
to log the calls received (I recall most QTHs)
Also, if I happened to "step" on anyone with
the SSTV xmission my apologies!
WH6BIE was the last station I heard prior to
my image xmit and the frequency appeared
quiet at that point. If anyone happened to copy
or hear the SSTV I would be enjoy hearing about.
73 to all.
Mahalo.

Just to give everyone a little update on how the AMSAT NextGen Program
is doing @ Binghamton University . . .
(a) CONTROL & EXPERIMENT SYSTEMS
- The Systems Engineering students are doing well analyzing the ARISSat
documentation and will be scheduling meetings with the primary AMSAT
engineering contact to discuss documentation questions.
- Identified Design Changes Needing to Occur for NextGen:
* The Control/Safety Timer needs to be adapted to conform with the
CubeSat deployment switch standard
* Consolidation of Camera functionality into a separate camera payload
board (functionality is currently spread across a number of boards in
the stack)
(b) RF SYSTEMS
- The Systems Engineering students are doing well analyzing the ARISSat
documentation and will be scheduling meetings with the primary AMSAT
engineering contact to discuss documentation questions.
- Identified Design Changes Needing to Occur for NextGen:
* Antenna design choice - single dual-band vs dual mono-band
* New RF container design needed
(c) POWER & STRUCTURE SYSTEMS
- The Systems Engineering students are doing well analyzing the ARISSat
documentation and will be scheduling meetings with the primary AMSAT
engineering contact to discuss documentation questions.
- The Hardware Engineering students have been busy creating a
preliminary design for solar panel deployment and use of supercapacitors
to replace the battery. A Preliminary Design Review is being scheduled
in mid-November with the AMSAT Engineering Team.
- Identified Design Changes Needing to Occur for NextGen:
* Replace Battery with modular stacks of Supercapacitors in parallel to
the Solar Panels
* Shrink ICB (Interconnect Board) to fit within CubeSat frame
* Reduce PSU footprint by moving camera power function to a Camera
Payload Board (CPB)
* Slight PSU voltage supply design change
* Remove test/program load functionality from ICB to external test board
(XTB) via standard CubeSat & PPOD maintenance ports (per CubeSat spec.)
We are still on-target to have an engineering model ready for the AMSAT
table at the 2010 Dayton Hamvention with readiness for launch later in 2010.

AO-51 38k4 bps Operations 16-19 November

From AMSAT HQ SILVER SPRING, MD.
November 15, 2009
To All RADIO AMATEURS
BID: $ANS-319.02
Okay 38k4 packet operators, get ready to start your engines!!
AO-51 is scheduled for a four day period of high speed packet
operations at 38k4 bps. It's been about 2 years since the satellite was
configured in this mode. The satellite will be in high power mode (only TXA
435.150 transmitter ON) during this period.
The posted schedule is as follows:
November 16 - November 19
38k4 BBS, L/U
Uplink: 1268.700 MHz 9k6 FM
Downlink: 435.150 MHz 38k4 FM
Usually this means the mode will run from around 22:00-23:00UTC
November 15 (Sunday evening Eastern US) until around 22:00-23:00UTC
November 19 (Thursday evening Eastern US).
Users of the PacketBBS are encouraged to send me feedback/reports on
your experiences during this period.
Please note that 38k4 packet operations require a receiver with
sufficient bandwidth and that your normal 9600 radio receive
connection will not work. Users also need a TNC that is capable of
running packet at 38k4. A special "wide" filter like the ones
available through Symek (www.symek.com) need to be installed in the
radio to "tap" a wide band signal. A few commercially available TNCs,
like the KPC-9612+ and the Paccomm Spirit-2 (with satellite option)
can be used.
You can use a PCR-1000 or PCR-1500/2500 as a wide band receiver,
without modification. Use the packet jack and set the receiver to FM
(not FM-W) with a 50 kHz filter width. If you have one of these
receivers, but not the right TNC, you might try Doug Qualigiana's
KA2UPW sound card software here: http://www.quagliana.com/willow/
It will decode at 9600 and 38k4. There was a an article about his
software in the AMSAT Journal just a few months ago.
Hope to see you active on AO-51 at 38k4!

AO-7 has 35th Birthday on 15 November
AMSAT News Service Bulletin 319.03
From AMSAT HQ SILVER SPRING, MD.

To All RADIO AMATEURS
BID: $ANS-319.03
Thirty-five years ago this Sunday (15 November), AO-7 reached orbit.
The following is from the AO-7 page on the AMSAT-NA Web site:
"AMSAT-OSCAR 7 was launched November 15, 1974 by a Delta 2310
launcher from Vandenberg Air Force Base, Lompoc, California. AO-7 was
launched piggyback with ITOS-G (NOAA 4) and the Spanish INTASAT. The
second phase 2 satellite (Phase II-B). Weight 28.6 kg. Orbit 1444 x
1459 km. Inclination 101.7 degrees. Octahedrally shaped 360 mm high
and 424 mm in diameter. Circularly polarized canted turnstile VHF/UHF
antenna system and HF dipole."
If you're not set up for the linear satellites but have a receiver
with CW/SSB capability on 2 meters, try listening to a pass. The
middle of her Mode B downlink passband is 145.950 mHz, and you will
find most of the activity occurring between 145.940 mHz and 145.960
mHz. Generally, you'll hear CW operators below 145..950 and SSB
operators above 145.950.

SatPC32 V.12.8a Upgrade Available for Download
AMSAT News Service Bulletin 319.04
From AMSAT HQ SILVER SPRING, MD.
November 15, 2009
To All RADIO AMATEURS
BID: $ANS-319.04
Erich, DK1TB has uploaded an upgrade of SatPC32 (V. 12.8a) on his
website http://www.dk1tb.de.
The V.12.8a update includes the following:
1. The main program SatPC32 can now manage up to 4 different
configurations. Configuration #1, for example, could steer a single
satellite transceiver to work the normal V/U and U/V satellites.
Configuration #2, for example, could steer a separate radio (FT-817,
IC-706MKIIG) as RX and the satellite transceiver as TX. This
configuration is useful for AO-51, mode V/S. Most users will receive
S-band with a 13cm/2m down converter and a 2m RX. Configuration #1 would
not work because the satellite transceiver cannot simultaneously receive
and transmit on the same band (2m).
The Keplerian data only needs to be updated with one configuration. The
new data will be used by the all configurations.
The configurations can be switched via mouse click in menu 'Setup',
'Configurations'.
2. In 'Real Time' mode the program updates it's calculations once per
second. With previous versions the update interval could not be changed.
Now the speed can be increased by 5 and 10 fold (menu 'CAT'). On the
higher bands the Doppler shift can change by 50 Hertz per second and
more. That will cause scale effects on the received signal. Due to the
narrow filters CW signals even can be lost. Increasing the update speed
can prevent these effects.
3. In menu 'CAT' a bottom line has been added. It displays the complete
data line from file Doppler.SQF. So, the optional comments at the end of
a data line can also be seen. That is particularly helpful with
satellites that provide multiple modes (i.e. AO-51 and ISS) and
therefore require multiple data lines in Doppler.SQF.
4. CAT steering of the Icom radios IC-706MKIIG, IC-7000 and IC-910H has
been simplified. With previous program versions the IC-706MKIIG and
IC-7000 required an extra line between the radio's ACC jacket and the
PC's COM port to inhibit frequency changes while the radio is
transmitting (because that would cause frequency errors). The IC-910H
required the line with SatPC32ISS. This line is no longer necessary.
5. The programs now works flawlessly on 64-bit Windows systems, except
rotor steering with the interfaces FODTrack, KCT, IF-100 and RifPC. The
kernel driver that is used to output data to these interfaces is a
32-bit version. A 64-bit version is not available yet. The KCT and RifPC
could not be used anyhow with 64-bit systems because they require an ISA
slot which is no longer supported by newer PCs.
The program also works flawlessly under Windows 7. It supports the
96-dpi (100%) and the 120-dpi 125%) fonts. It does not work properly
with the new 144-dpi (150%) fonts. Program versions 12.8 and older work
only with the 96-dpi fonts.
6. The CD and the Internet Setup File now include the tool
DataBackup.Exe. Via a single mouse click, the program can generate a
backup copy or restore the entire SatPC32 data folder (all personal
settings). That is particularly helpful when the program is upgraded.
7. Some bugs have been fixed (concerning, i.e., downlink correction and
transverter operation).
THANK YOU to Erich Eichmann DK1TB for creating and
continuously enhancing SatPC32 for the global amateur satellite
community. And for donating it to AMSAT-DL, AMSAT-NA, and AMSAT-UK.
SatPC32 is surely the most lucrative fund raising item for these AMSAT
groups.

High Altitude Balloon Project Seeks Student Applications
AMSAT News Service Bulletin 319.05
From AMSAT HQ SILVER SPRING, MD.
November 15, 2009
To All RADIO AMATEURS
BID: $ANS-319.05
The SpaceDaily Express newsletter carried the announcement that NASA
is accepting applications from students at U.S. colleges and univers-
ities who want to send their experiments to the edge of space on a
high-flying scientific balloon.
The annual NASA project provides near space access for 12 under-
graduate and graduate student experiments to be carried by a NASA
high-altitude research balloon. The flights typically last 15 to
20 hours and reach an altitude of 23 miles. Experiments may include
compact satellites or prototypes.
The experiments are flown aboard the High Altitude Student Platform,
or HASP, a balloon-born instrument stack launched from the Columbia
Scientific Balloon Facility's remote site in Fort Sumner, N.M.
The goals of the project are to provide a space test platform to en-
courage student research and stimulate the development of student
satellite payloads and other space-engineering products.
HASP seeks to enhance the technical skills and research abilities of
students in critical science, technology, engineering and mathematics
disciplines. The project is a joint effort between NASA and the
Louisiana Space Grant Consortium.
NASA's HASP houses and provides power, mechanical support and communi-
cations for test articles and instruments. It can support approximately
200 pounds of student payloads. Since 2006, the HASP program has
selected 44 payloads for flight, the work of more than 200 students
from across the United States.
The deadline for applications is Dec. 18. NASA is targeting fall 2010
for the next flight opportunity. NASA expects to make selections in
January 2010.
