Just relaying this from the news on QRZ.com. SouthGate ARC site was
mentioned also ...
The subject for this week's "Technology Net" is Understanding and working
the Amateur Satellites, presented by Ron Nutter, KA4KYI.
Being the AMSAT Area Coordinator for Missouri, Ron will introduce you to all
the AMSAT Satellites as well as the many Satellites launched by other groups
around the world. Having made contacts himself to all states in the
Continental U.S. he'll explain every combination of equipment to work the
birds from handheld to mobile to fixed location. He'll explain how and what
you'll need to get into one of the most exciting forms of Amateur Radio.
If you go to our website you will see all the "Technology Net"
presentations. If you click on the top listing you will be going to Ron's
website with many pages of information to support his presentation. There
will be a question and answer period at the end of his presentation for you
to ask any questions you have. We'll also be posting a recorded version of
his presentation on our website afterwards, for anyone that misses it.
http://k0gq.com/technet.htm
The Technology Net is on the Raytown Missouri Amateur Radio Club repeater at
8:00 pm Central time U.S. Friday November 13, on 145.170(-) no PL tone.
Or you can listen from anywhere on the Internet at these locations:

Hey everyone,
During the 2045-2046 UTC portion of the AO-27 pass over the western U.S.
today (11 November), Sawson (KG6NUB) and I completed a two-way contact with
handheld stations that were each transmitting 50mW (.05-watt) out. Sawson
used?a Kenwood TH-D7 with an Arrow, and I used a Yaesu VX-7R with an Elk.
Including the published, nominal transmitted power of AO-27 (500mW), our
"power budget" for the contact was 600mW, or .6-watt.
I'm thrilled to post this item to the BB. We didn't?use?a specially
scheduled QRP pair of frequencies to complete the contact. We were in the
middle of all the other stations working the pass, and were able to complete
a 2-way contact using milliwatt power.
I especially hope our friends with AMSAT-South Africa will note and pass
along this information in advance of their Activity Weekend, which is coming
up in a couple of days. Their goal is to stimulate interest in and activity
on all of the amateur satellites among South African amateurs. Our FM
satellites are definitely reachable with handheld stations - even those
running 1/10 the power of the satellite itself!

My apologies to everyone for this re-post. Actually, it was my original
attempt at posting this. I sent it right after the pass yesterday. When it
didn't show up by this morning, I re-sent the post everyone saw several
hours ago. I didn't think this one was going to make it.
Sorry for the repeat.

I haven't heard any activity on SO-67 since the mode vu repeater was on last
weekend. Is the satellite in a different mode? If so what is the downlink
frequency of the beacon? Any information would be appreciated.

SO-67 is only turned on occasionally for testing at this point. The
schedule is posted on their web site, sometimes with very short notice:

Hi Dave N2AAM
SO-67 SumbandilaSat is skeduled time to time by the South Africa Command
Station and the skedule is also released on this AMSAT-BB
I don't think SO-67 has a beacon or another mode except a V/U repeater. The
Uplink is 145.880 MHz FM and Downlink is 435.350 MHz FM

Tim, Sawson and I frequently have such contacts on AO51, SO50 and AO27, and
we would invite anyone with a duplex handheld like our D7s, and elks, arrows
and even AR800s to give it a try. The high passes are the easiest, but
folks would be surprised how well 50 mw radiates through space at most any
elevation!

I have uploaded two AO-51 audio files to my webserver.
The first is the 12Nov2009 2241Z pass with AA5CK/P
operating in EM03. The second is the next pass on
13Nov2009 at 0023Z that includes AA5CK/P in EM03 and
another not often heard from grid, CN83, with W9AE operating.
The second recording is a little over 9 minutes as this
was only a 6 degree pass for me here in Cleveland.
Thanks to both Ted and Wayne for activating these grids
for all of us collecting them for our satellite VUCC!

Hi! there Tim, Craig and Sawson, I like to comment that I also worked Sawson
at his "50 milliwatts on a whip" but thats not it, he was able to complete a
qso with Hawaii using such extremely low power, as I mention in a past post,
when I finally got an extra handheld to add to my satellite station and
unmarried from the arrow II antenna diplexer it was on my mind to become a
satellite hog and power up my transmitter to 50 watts, but on the test day
Sawson just show up using his famous call "KG6 November uniform bravo 50mw
on a whip" that makes me go back to QRP mode again and try the challenge!

Hi Erich,
Thanks for the great upgrade. I see you incorporated the CW-N mode and
the display of the DOPPLER.sqf line in the CAT menu I suggested :)
You are correct, one of the issues with fast changes in Doppler on a
CW-N signal is that it jumps in pitch a lot. I enabled the x5 and x10 mode
and I can see SatPC32 is now polling the IC-910 much quicker (the SUB
light on the LCD flashes an instruction is sent to the rig via C-IV). But
what I cant figure out is that even if I set the CW/SSB interval
to 10Hz, the rig only changes every 100Hz. When I make small changes
to the VFO by rocking the dial back and forth on the rig the full update to
the goes
back to the frequency display in SatPC32 right down to the last Hertz but
as soon
as I let go of the VFO knob the IC-910 jumps to the nearest 100 Hz increment
up or
down when the next C-IV instruction is received from SatPC32.
So it seems the full frequency command is going from the IC-910 to SatPC32
but its not accepting it from SatPC32 ?
Or am I missing something ? Maybe someone else can test and confirm this.
73's and Best Regards,
Allan ZS1LS

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.

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. If memory serves me correctly, it's been
about 2 years since the satellite was configured in this mode. The
satellite will be in high power mode (only TXA 437.150 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!

The frequency for the 38k4 operation is 435.150, not the 437.150 that
I typoed. :)
Sorry for creating confusion.

Hey everyone,
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."
I consider it good fortune that the Grand Old Girl will be in Mode B on her
35th birthday. According to information from Hal, ZS6WB, in South Africa,
her daily toggle between Mode A and Mode B has been occurring very close to
0445 UTC, when at least a portion of South Africa?usually is in her footprint.
So - from 0445 UTC on 15 November to 0445 UTC on 16 November, AO-7 should be
in Mode B (UHF uplink - VHF downlink). I'm hoping she stays consistent!
Let's celebrate her historic longevity and make Sunday a very busy day for
AO-7. I intend to work every pass I can, and I hope everyone else who has
Mode B capability will do the same.
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.
Here is a link to the online log for AO-7:
http://www.planetemily.com/ao7/ao7log.php
Check it out.
AO-7 has lived a historic life. As I type this, the AO-7 log shows that she
is completing orbit No. 160,155.
Let's celebrate her birthday with as many QSOs as possible on the grandest
satellite in the current amateur fleet. That's my opinion, of course - but
I'm confident it's shared by many who have enjoyed AO-7 over the past 35
years.
73 to all,
Tim - N3TL

Hello all............barring any unforeseen problems, next Wednesday,
11/18/09 I will take a quick trip up to DM07 Grid to fulfill some requests
for that grid, plus hopefully it wont be a bust like last time. The data is:
AO-27 @ 2041 utc which is a 25 deg pass
SO-50 @ 2238 utc which is a 23 deg pass
I had hoped to work the intersection of CM86/CM87/DM06/DM07 except it is in
the middle of large Almond orchard, so will just stick with DM07.
I will be using the Yaesu FT-60R ht + Elk dual-band yagi, like I did when on
vacation last month.
Hope to work as many as I can for those 2 passes. QSL direct (no SASE
required) or eQSL.cc This Grid Location, DM07 is mostly rural and
mountainous, where Yosemite is located. I will be in the SW corner, in the
valley so wont be blocked by the Sierra Nevada's.
Look for all.
John W6ZKH
