Hi : Just go to the hamfests and they give nice color Grid square
maps for free.
In the last year I get one or two and give them away at the
club meetings.

Didn't someone post a video link of the new Kenwood HF radio and APRS HT
from the 2009 Tokyo Ham Fair a while back? Or maybe that was another
email list anyway I still have the link in my bookmarks:
http://www.youtube.com/watch?v=O_GCvYfbKgA
New HT is shown starting at 2:16 in the video.

Good point, Allan. Actually, I was especially thinking of doing this
in some sort of arrangement that avoided the duplexer, perhaps using
an FT-817 on FO-29.
Even with the duplexer, there might be some solutions to the problem
you present. For instance, one could try making some sort of
vox-enabled power switching for the preamp, which turned it off when
one began to transmit. Then you'd at least have the benefit of the
preamp when you were copying the other station(s).

If i had to guess, it's prob the least amount of effort to make it
ROHS compliant, and maybe tweak a few things that wouldn't run
up the $$
drawing heavy on the D7 vs a redesign
Looks nice very similar to it's successor

Bruce,
Funny this should come up. I was doing some research on what kind of
luck folks had with Ramsey preamps and came upon this link...
http://www.worldwidedx.com/home-brew-mods/35101-ramsey-pr40-440mhz-preamp-kit.
html
I don't think this guys application used a diplexer and my 70cm antenna
will be strictly receive as well but this struck me as kind of what you
were talking about doing with the ARR unit.
73,
Michael, W4HIJ

Hi David
Happy to help in any way I can. I can see updating web pages as a way I can
help to some small degree. Recently clicked on amsat sites where some pages
have not been updated in years. Even if the info is still valid it looks
bad.
Having worked in education am happy to get involved in that direction, you
will know that experience.

Sadly no I don't have any 2m design experience, my design experience is
mostly high voltage switch mode PSU for powering Traveling Wave Tubes, and
the microcontroller based management systems for controlling high power

Hi Steve.
Thanks for the reply. Always good to know that someone is interested in
supporting the AMSAT cause. The ESEO project is being funded (hardware only)
by AMSAT UK while the launch is supplied by ESA Education. It's an
educational project with a small role for AMSAT. Currently we need some
expertise for a 2m TX and some satellite antennas...although hopefully the
antennas shouldn't be too much of a problem.
http://www.esa.int/SPECIALS/Education/SEMA0NEMKBF_0.html
Great on the PSU for TWT's. - with the microcontroller aspect of management.
Perhaps I can 'store' that in case we need a hand in those areas in the
future. Is it the PIC variety or ARM or some other specialised type you are
familiar with?
I'm working at a school as a science technician at present, so possibly I
can appreciate your working environment quite well. Half term in 3 days. -
Yippee.
Regards
David

John and all,
Well-said.
It's sad that some continue to intentionally and maliciously jam AO-51
during operations like Richard's, but it appears to be something with a
history. I heard (off the board) of cases just like the one I posted about
over the weekend that date back almost a decade involving other satellites.
It's sad.
You're also very right about how a Special Event can, indeed, draw folks to
the satellites. The 13 Colonies and K5E events earlier this year are other
examples. I hope more people will consider including the satellites, moving
forward, as they plan their special events. If you are reading this and
learn of a special event coming up that interests you but does not include
the satellites, contact the operators and ask them to think about including
the birds.
Thanks to everyone for taking the time and making the efforts to make this
weekend so dynamic on the satellites. It was great fun!
73 to all,
Tim - N3TL

Subject: [amsat-bb] Weekend on the Birds
This past weekend on the birds was second to
none that I've experienced in the past two
years..? We had grid dxpeditions on the east and
west coast, two hamfest demonstrations, the Boy
Scout Jamboree stations and an Alaska Statehood
special event station operating.
Patrick, WD9EWK, was at the Old Pueblo Radio Club
Hamfest in Tucson and made a big detour to continue
down I-10 to the Arizona/New Mexico state line where he
operated from in the afternoon.? Doug, KD8CAO, was at
the Holland Michigan Lakeshore Super Swap Hamfest and
put on a demonstration there.
Mark WA8SME operated on one AO-27 pass from the DN00/DN01
grid boundary, two very rare Nevada grids.? John W6ZKH
operated from DM07 but had some trouble with his equipment
on this particular pass.? He said he will go back some day.
Mark also said he might be able to operate from DM07 in the
near future.
Then we had the Boy Scouts Jamboree on the Air with quite a
few different stations operating on all of the FM birds including
K2BSA/5, W0S, K5B etc.
The most prominent grid dxpedition this weekend was by Richard,
N2SPI.? He had originally planned to operate from FN53, FN56,
FN57, FN66 and FN67 but he found a way to also operate from FN55
and FN65 as well.? He worked on the FM birds as well as VO-52.
This operation began Saturday morning and finished up Sunday afternoon,
about 30 hours from the first qso until the last on AO-27 at 1853z.
Richard operated at least one pass in each of seven grids and never
operated on a grid boundary.? This was quite a trip!? Richard
returned back to Massachusetts late Sunday night.
The weekend rounded out with an announcement to look for KL5O, an
Alaska Special Event Station, on the birds.? The AO-7 pass Sunday
evening at 0043Z had at least 14 different stations operating
including WV9E, KE5GFJ, WA4NVM, AA4FL, AA5PK, K6CDW, KE2CKO, K0OU,
K3SZH, AJ9K, KD8CAO, W7LRD, K8YSE and KL5O!? KL5O was down around
937 late in the pass.? So if you think that there is no one on AO-7,
this should put that thought to rest. Many of them were talking about
KL5O.? A special event does draw people to the birds just like it
does on the HF bands.? Of course working Alaska is a special treat
under any situation. I believe KL7XJ was the operator.
Activity is on the rise on the SSB? birds in general.? Many that have
been active on the FM birds are getting equipment set up for the
SSB/CW birds. It's nice to be able to have a qso that involves more
than a callsign and grid exchange.? We hope to have FO-29 back soon
but VO-52 and AO-7 are there for us every day.
A big thanks to all of the grid dxpeditioners who spent a lot of time
and money operating from places away from their homes.? They have given
us many new grids.? I hope this encourages others to try their hand
at operating from other grids.? It's a lot of work but you will have
a lot of fun and satisfaction doing it.
73,
John K8YSE

The PIC microcontrollers are frankly *dreadful*, without a single
redeeming feature. What makes me like them even less is that you're
forced to use the bloody awful Windows software to program them, and the
programming hardware is extremely finicky. There is a PIC assembler
that runs under Linux, but it sucks elephants through very fine mesh.
I've ditched all my PIC stuff and now use AVR, which is extremely well
supported on Windows, Mac OS and Linux. It's a better product, the CPU
core is generally faster clock-for-clock and it's only slightly more
expensive. How much is your time worth?
If you're not convinced yet, buy an Arduino board. You probably
couldn't put together an AVR board for less in onesy-twoesy quantities.

A grid dxpedition to EM97 in West Virginia is planned for Saturday
afternoon October 24th. It's about 600 miles round trip so the first
pass of AO-27 at 1734z will likely be the beginning of the
operation. Then AO-27 at 1912z, AO-27 a 2054z followed by AO-51 at
2200z and possibly 2339z if it's not too dark.
West coast stations should try for the 2054z AO-27 pass since the
2339z AO-51 pass could be dropped. West Virginia is very mountainous
and it is difficult to find a high point that can see down low to the
horizon. That and the fact that there are not that many hams in this
grid are likely the cause of it being uncommon.
There are no digi's close to where I will operate but there may be coverage
from mountaintop digis far away. Track with k8yse-8. I'll also have
the ISS APRS radio going which might relay the position to the aprs servers.
Unfortunately, there will not be any ISS passes while I'm at the operating
location, however, there will be passes in the morning on the way down.
The APRS radio is k8yse-9. I will attempt to operate on the way down while
in motion.
I'll have HF capability on the way, probably on 40 meters most of the time.
The weather forecast is for rain and possible thunderstorms. I hope they
will not be too severe. As long as it is not lightning, I will operate in
the rain somehow.
Please email with suggestions and/or schedule requests. As always, no qsl
card is necessary. All contacts will be confirmed.
73,
John K8YSE

Hi David
Happy to help in any way I can. I can see updating web pages as a way I can
help to some small degree. Recently clicked on amsat sites where some pages
have not been updated in years. Even if the info is still valid it looks
bad.
Having worked in education am happy to get involved in that direction, you
will know that experience.

Hi David
Sadly no I don't have any 2m design experience, my design experience is
mostly high voltage switch mode PSU for powering Traveling Wave Tubes, and
the microcontroller based management systems for controlling high power
travelling wave tubes + PSUs. Mostly I have done the microcontroller aspect
of that. Over recent years I have been mainly involved in I.T. admin in
schools

Hi Steve.
Thanks for the reply. Always good to know that someone is interested in
supporting the AMSAT cause. The ESEO project is being funded (hardware only)
by AMSAT UK while the launch is supplied by ESA Education. It's an
educational project with a small role for AMSAT. Currently we need some
expertise for a 2m TX and some satellite antennas...although hopefully the
antennas shouldn't be too much of a problem.
http://www.esa.int/SPECIALS/Education/SEMA0NEMKBF_0.html
Great on the PSU for TWT's. - with the microcontroller aspect of management.
Perhaps I can 'store' that in case we need a hand in those areas in the
future. Is it the PIC variety or ARM or some other specialised type you are
familiar with?
I'm working at a school as a science technician at present, so possibly I
can appreciate your working environment quite well. Half term in 3 days. -
Yippee.
Regards
David

The ARRL sells a plain black 11x17 inch grid map of North America for
$1. No color, no gray scale. Perfect for coloring in the grids as you
work/confirm them.
http://www.arrl.org/locate/gridinfo.html
A smaller version of the map is also in the ARRL Operating Manual and
perhaps in the ARRL handbook. I scanned, printed, and laminated the
page from my ARRL Operating Manual.

SB SAT @ AMSAT $ANS-294.01
SumbandilaSat Designated as SO-67
AMSAT News Service Bulletin 294.01
>From AMSAT HQ SILVER SPRING, MD.
October 21, 2009
To All RADIO AMATEURS
BID: $ANS-294.01
AMSAT's OSCAR Number Coordinator Bill Tynan, W3XO announced he has
received an e-mail sent to the AMSAT-NA Board of Directors by Hans
van de Groenendaal, ZS6AKV, Secretary SA AMSAT requesting that an
OSCAR number be allocated to SumbandilaSat.
In the e-mail Hans states that the amateur radio transponder on
SumbandilaSat was successfully switched on from the ground by ZS6BPZ
during the test phase on Sunday 18 October 2009 and that several QSOs
were made through the transponder.
The amateur radio payload on SumbandilaSat was developed by SA AMSAT
and incorporated by the University of Stellenbosch into the main pay-
load. The SA AMSAT payload was officially coordinated through the
IARU Satellite Frequency Coordination Panel with an uplink of 145.880
and downlink of 435.350 MHz
Bill replied, "Therefore, by the authority vested in me by the
AMSAT-NA President, I hereby designate this latest amateur radio
satellite as SumbandilaSat Oscar 67 or SO-67. On behalf of AMSAT-NA
and the world's amateur radio satellite community I congratulate those
responsible for building, testing and launching this new satellite.
May it have a long and successful life."
[ANS thanks Bill Tynan, W3XO for the above information]

I couldn't agree more. I'm in the process of updating some of my
old PIC projects which has reinvigorated my interest in amateur
satellites and amateur radio in general.
