Has anyone used the Elk 2M/440 Log Periodic Beam Antenna mounted on a Camera
Tripod?
I would appreciate your experience/technique in mounting it.
Thank You,
Vince, WB2FYZ

I will be putting W1AW on AO27 for a demonstration (HT and ARROW) during the
teachers institute on July 28 (Tuesday) probably during the 1216(L) pass.
Your assistance with the demonstration would be appreciated. If you would
like a QSL of the contact, please send yours to WA8SME, and I'll take care
of it. No SASEs required.

It's great to see the renewed interest in activating
"rare" grids on the birds. If you don't have a particular grid
worked and confirmed, it is a "rare" grid. It is important
for all of us to recognize those who are operating "portable"
in a grid away from their home. They are only there for a
short period of time so giving them the frequency is the thing
to do. If you hear a callsign that you have not worked before,
call that person rather than someone you just talked with on
the last pass. We need to encourage the new people as they are
the future of the amateur space program. Use the portable
designation if you are operating away from home so others will
know that this might be a new grid.
We have enjoyed a long stretch of AO51 being in the V/U mode on
435.300. After the end of the month, the bird will be in sunlight
continuously and that will allow higher power and other modes to be
used. If AO51 is in a non-V/U voice mode, as it was for a 2 week period
not long ago, grid dxpeditions are not going to be worthwhile. If
you plan a vacation ahead of time, you might find later that the bird
will not be in a v/u voice mode during your trip.
The Operations Team sets the schedule and they do it based upon
requests from the membership for alternate modes. Personally I think
that there should always be a 435.300/145.92 mode available. Everyone
who is interested in chasing grids or activating grids away from their home
should email KO4MA and request that V/U voice remain on. You cannot
plan anything if you don't know if AO51 will be in V/U voice during your
trip. The schedule is based upon input from the membership and if we
don't make our requests, those that want the bird in other modes (both
transponders) will most likely be served. The second transponder is fine
for other modes but there are probably some modes that cannot be activated
if V/U voice is to remain on. Maybe Drew can clarify this for us.
There are some that would say that there are other satellites that can
be used for FM voice. Very true, however, if you are out there trying
to activate grids, not having AO51 available is a handicap. You spend a
lot of money to do it and then have 1/3 of your potential air time, on the
best FM satellite up there, not available to you. It makes no sense.
I'm on L band now and will have S band RX running soon. I enjoy setting
up for different modes. But after you work a few stations in those modes,
and fine tune your equipment, there's not much left. Chasing grids never
ends. There's always one more to work.
If you are interested in working or activating new grids, please email KO4MA
and request that AO51 always have one V/U voice transponder available. There
is no guarantee that this will always work, but if there are no emails, it is
likely that there will be more periods of non V/U voice on AO51.

John,
I certainly understand where you are coming from, although I disagree with
some of your positions. AO-51 is currently our only satellite with multiple
modes (other than ISS), our only S band satellite, our only BBS, our only L
band satellite, etc. Unfortunately our power budget doesn't allow us to run
every mode we want to at the same time. This problem will only get worse as
the batteries age. We are already at the point where after this extended
period of mostly full illumination, we will most likely only be able to run
one transmitter at any time, and possibly not the S band in eclipse
at -all-.
The good news is that the full illumination lasts for quite a while, and
during this period we can support two UHF transmitters at a high power
level, or one UHF at modest power and the S band transmitter. If we run
separate S and UHF, the UHF downlink will have to be on 435.150, as the
435.300 and S transmitters share an audio path.
So...that being said, do not expect us to completely forego L and S just for
more grid swapping, as fun as it is (I'm at 550 confirmed). Send your
requests in early for whatever mode you'd like, and we will try to honor
them. Meanwhile, get your S band downconverters ready for portable ops, your
817s and 706s working with SatPC32 on a laptop, and be ready to occasionally
run your grid trips on ALL the satellites. It's a real shame to hear so many
ops on V/U FM, and so few on V/U and U/V SSB/CW.
Since I try to walk the walk, look for me on the SSB -and- FM birds as G/
and OZ/KO4MA over the next 2.5 weeks. I hope to stretch the footprint to
North America on FO-29 and AO-7 with my little 817 and Arrow setup.
Mode requests should go to ao51-modes@xxxxx.xxxx not to me direct.

Please excuse me for posting this, but in this tight job market I felt
might be of interest to some AMSAT or ARRL folks.
I know of job opportunities for someone in the San Diego area that has
either satellite or submarine communications experience in the DOD. If
you have either or both, please contact me OFF LINE and feel free to
send your resume. Thanks

Hi AMSATs,
Last weeks I have been working on a testboard for the very small linear
transponder system that I have designed.
I plan to be at the JARL Ham Fair in Tokyo, Japan on 22nd and 23rd August,
where I will present my thiny linear transponder to the ham people.
I will be in Japan from 15th August till 27th of August.
When some University Cubesat group in Japan is interrested in my transponder
design I can give demonstration and presentation.
Only serious parties please.
Please see some older movies about my transponder design on youtube:

ok so what about this question,
say you are going to go on vacation or moble /expadition,
and you know that they?are changeing?AO-51 to say L/S mode for next week,
?
would a HT that has L band FM transmit (DJ-G7T) 1 watt
be ok or would you a 10watt amp with the proper antenna,?
to kick the bird :-)
i have the S band covered almost.?

HI,
I'm looking for any simple source code in C-language for FX-614 (ax.25
decoder) for undestanding simple ax.25 protocol. I found only few
asm code for PIC16, but c-lanugage is easily to adopt to other
microcontrollers.
I tried to connect FX614 IC like in HITSAT
http://www.hit.ac.jp/~satori/hitsat/img/decord.bmp and read at RX PC
port with rs232 terminal programme,
but I didn't receive any useful frame with b011111110 start (like
describet in ). After this I found that all modem using pin CTS on
RS232 port, I don't know how to handle this with
PC to read directy with rs232 RXD port like HEX or binary values to
see raw values of packet frames?
It is possible to read values from FX614 (through max232 ) with PC to
see raw format?
So I'm looking for any simple source code in C to find how to decode
signal from fx614 to microcontrollers port and then to PC
Thanks for your help
all the best Andy

Don - You will be receiving a "corrected ballot" in the mail shortly. It

Hey everyone,
K5E - The 40th Anniversary Apollo 11 Satellite Special Event - has concluded.
My thanks to everyone for making this a fun and memorable special even on the
satellites.
Here's a brief summary:
The K5E log contains 338 contacts representing 182 different operators.
Contacts took place on all of the FM satellites (AO-27, AO-51 and SO-50), all
of the CW/SSB satellites (AO-7, FO-29 and VO-52; both CW and SSB contacts are
in the log), and via the International Space Station. The ISS contact was a
two-way direct-packet contact between K5E and KB1GVR, in Maine.
I will post a more detailed summary in the near future.
Thanks to AA5PK, K8YSE and WA4NVM who assisted by operating portions of the
special event as (their calls)/K5E. Their assistance proved valuable in
expanding coverage throughout North, Central and northern South America.
QSL Cards are in transit from the printer! Thanks again to Glade Schroeter,
WA3MVQ, and GGGraphicsstore.com for donating the cards.
My goal is to have all on-hand QSL requests filled and back in the mail by no
later than July 31. If you worked K5E and have not requested a QSL card,
please do so with an SASE. Direct all QSL requests to N3TL at the address on
QRZ,com/N3TL.
Thanks again to all, and 73,
Tim - N3TL

Drew,
I appreciate your comments about what AO-51 can and cannot do.
There is no problem if the v/u mode comes down on 435.150 rather
than 435.300 except for the polarization difference. Those with
Right Hand Circular Polarization (RHCP) will have a difficult time
hearing the Left hand (LHCP) downlink. Those with yagi's etc won't
be affected and that includes most of the new people. A downlink
on 435.150 is better than no UHF Voice downlink at all.
As far as dxpeditioners working ssb birds, most of us can do that.
But who are we going to work? - only the few that have ssb equipment.
The new people starting out are likely to only have a FM handheld
or mobile. These are the people that will be going for their first
award. As they progress, they'll start working towards their first
100 grid VUCC award and maybe Worked All States, especially if they
are on the west coast and can work Hawaii on a FM bird. We cannot
expect everyone to invest in L and S band equipment to work the
handful of people who operate those modes. If it weren't for the
people that bought their radios/antennas/converters a long time ago,
even fewer would be operating L/S.
It's a lot harder to work grids now than it was years back. If you
worked your 550 grids on birds that have the footprint of AO-51,
you're a stellar operator. These days you have to pull out the stops
to do it and if it weren't for the grid dxpeditioners, it would be
tough to do half that amount. Without V/U FM, you don't get to
those totals very fast, if ever, on today's birds.
There does need to be a balance between modes and AO-51 is certainly
a versatile satellite that can serve many different interests. What
we need to keep in mind is that new people are the future of AMSAT. If
they don't have an FM voice mode, there is no other likely entry point
for them. And if no one is going out on grid dxpeditions because there
is so little v/u airtime per day, the organization will never grow.
There would be no interest in DXCC if there were no dxpeditions. I think
that there would be a lot less interest in operating satellites if there
was no VUCC and grid dxpeditions to facilitate working something new on
a regular basis. Making a contact with the same people over and over
gets old quickly. Put someone like WD9EWK in Utah, ND9M all over the
eastern US including Delaware, KD8CAO in northeastern Michigan and Drummond
Island, KB0RZD on a 4 corner grid boundary in Missouri and even K8YSE
in Delaware
for those that missed ND9M, and AO-51 COMES ALIVE. XE2AT who is
at the top of the VUCC leader board with over 900 grids worked is in
there calling KD8CAO in EN86 and EN76. There are no pileups on L/S
and the BBS.
That being said, I only ask that configurations that preclude a
FM V/U transponder be kept to a minimum. We need to do everything we
can to encourage new people to enter the world of satellites and we
need to support those who operate from other grids and give everyone
something to work for.
I will be listening for you on AO-7 et. al. Have a great trip. Don't
forget to post your operating schedule on the amsat-bb so we know
when to look for you and what grids you'll be in.

John,
I certainly understand where you are coming from, although I disagree with
some of your positions. AO-51 is currently our only satellite with multiple
modes (other than ISS), our only S band satellite, our only BBS, our only L
band satellite, etc. Unfortunately our power budget doesn't allow us to run
every mode we want to at the same time. This problem will only get worse as
the batteries age. We are already at the point where after this extended
period of mostly full illumination, we will most likely only be able to run
one transmitter at any time, and possibly not the S band in eclipse
at -all-.
The good news is that the full illumination lasts for quite a while, and
during this period we can support two UHF transmitters at a high power
level, or one UHF at modest power and the S band transmitter. If we run
separate S and UHF, the UHF downlink will have to be on 435.150, as the
435.300 and S transmitters share an audio path.
So...that being said, do not expect us to completely forego L and S just for
more grid swapping, as fun as it is (I'm at 550 confirmed). Send your
requests in early for whatever mode you'd like, and we will try to honor
them. Meanwhile, get your S band downconverters ready for portable ops, your
817s and 706s working with SatPC32 on a laptop, and be ready to occasionally
run your grid trips on ALL the satellites. It's a real shame to hear so many
ops on V/U FM, and so few on V/U and U/V SSB/CW.
Since I try to walk the walk, look for me on the SSB -and- FM birds as G/
and OZ/KO4MA over the next 2.5 weeks. I hope to stretch the footprint to
North America on FO-29 and AO-7 with my little 817 and Arrow setup.
Mode requests should go to ao51-modes@xxxxx.xxxx not to me direct.

I think I'm going to get a used Elk ant to mount on top of my 20ft
tower or at least would like to. It would go on the top of the lil
20ft tower and 5 ft above it would be a 9 el 2m yagi. The mast is
metal and I'm wondering how to mount it to the mast and mostly will
the metal mast work ok???

hi
Am in the planning stages of designing a satellite setup
and decided on M2 2m and 430 antennas.
They are RHCP out of the box , but I can buy a kit to enable them
to switch between that and LHCP.
It's kinda expensive and since I am inxperienced in this
regard, hope someone might offer some thoughts if it's truly
going to come in handy.
Guess with AO51 maybe ?
Thanks
Going to Dayton '10 It will get better with
more support!

Hi Jerry,
I have an Elk Antenna. Are you able to install the Elk antenna on top
at the end of your mast ?? I did this on my portable setup Buddipole.
The Elk antenna is over the dipole using ABS fitting that make the
installation very solid.
I don't have any picture... sorry.

Hi Vince,
I did this last year. But I found a little difficult to control
properly the antenna over the tripod. I finally did a handle that I
can hold in one hand. I also tought that sometime I could installed
the Elk antenna in piggyback over my Meade LX-200 10' telescope. The
antenna is very lightweight, the telescope can be easly control to
track the satellite.... even remotely !!!

Though you may find the Elk construction to be a little flimsy for a
permanent installation, you should be able to "end mount" the boom with
little significant distortion of the pattern.
Using some aluminum plates and a few bolts or U-bolts should work. Remember
your 15 degrees of elevation for the satellite "sweet spot" (there are many
of those who suggest more, not many less.)
Realize you will lose the flexibility of "hand polarization" that it offers
on the ground and enjoy!

I find that both the portable Elk and Arrow antennas elements unscrew over
time.? Outside in the elements, you may soon find a bare boom unless you
secure the elements to the center boom.

Hi folks,
I recently treated myself to a new toy - the Nokia N810 "Internet Tablet".
(Think iPod Touch with a higher resolution screen, real GPS, real keyboard,
and it runs Linux so the apps multi-task, and are free.) Thought I'd pass
this on...
One of the challenges I faced in this consolidation was finding equivalent
apps to the ones I was using on multiple other platforms, including some sort
of satellite tracking program. I figured I could at least port Predict over,
given the Linux software base. Then I found the Garnet VM program, which is a
Palm virtual machine. Loaded it up and installed PocketSat+, and it works
really well. In fact, it's faster on the Nokia N810 than it was on my Palm
Vx. Just be sure to get all the various clock settings right, between the
N810, virtual machine, and the application right, so you don't apply daylight
savings twice.
Enjoy,
Greg KO6TH
