Hi AMSATs,
The tinny transponder design is finished and tested. I can make copies when
there is interrest. My visit to Ham Fair in Tokyo was for me a kind of
milestone to finish the design and make it public to the people. (I like to
design something well done, before make it available to others, this avoids
modifications and extra work later).
It is not easy to make the LE005-R2 transponder design without having the
right tools. This is also the reason why I cannot sell it like a kit for
people to solder at home.
The design is made at a profesional level (as development engineer I am
dealing with it dayly) and can be made with use of a pick and place machine
and reflow soldered for large quantities in a factory when needed. This is
only profitable at large quantities.
For small quantities its cheaper and faster to do it with my small reflow
system. The quality is guarenteed as I can do manual inspection and full
testing myself.
The next step is doing space environment tests, but that takes some more
time and money. In case you have a working thermal vaccuum chamber in your
garage, let me know ;o)
The LE005-R2 is designed for space environment but not officially tested
yet.
However, the design is well suited for applications like terresterial
transponders.
73, with kind regards,
William Leijenaar, PE1RAH

Fun day .. My FT 897D arrived..
Learning all the menus and features is always a great time ;)
I do have a couple of questions about the rig if there is a
Couple of you on the list that have a lot of experience
With it.. Mostly to do with digital modes and / or just using the
Audio out / in for PSK , etc.
The other is that I want to switch to WFM at 137.XXX for the weather
Satellites and doesn't look like the rig will do that?
My yaesu G5500 came as well .. Damaged .. :(
So it has to go back .. Even took a day of to have fun soldering and
Getting it up on the mast .. Oh well ..
Anyways.. Any knowledgeable ( on the FT-897 ) volunteers out there in the
crowd ??
Randy - N2CUA
PS .. Thanks so very much for all the help the list has provided ..
You all are super !!!

The digipeat APRS/text signal on multiple LEO'S is could be an alternative
solution to a HEO but i will go a bit further and is it possible
to have DSTAR FM transponder on multiple LEO'S? With the new small size
transponder made by William PE1RAH it will be something to
investigate. DSTAR can even send APRS data D-PRS and digital audio in the
same transmission.
Do not forget that any analog FM repeater which does not filter CTCSS tone
(audio taken at the discriminator directly) can transmit D-Star
signal.
Since my first experience with DSTAR i firmly believe a small cube sat will be
soon be possible and with the fabulous linking capabilities
of DSTAR communication protocole it will also be possible to have of some sort
of intersatellite linking system.
Remain to see how to have a wide FM transponder.
As DSTAR is quite in advance in Japan i will not be surprised to see something
coming out there. With the new JAXA H-II transfer vehicule
did we overlooked a launch opportunity? again our Japanese friends seems to be
quite impress with William pico transponder! did they have
something in mind?
Here is some link of interest.

P.S. I am looking for someone with DSTAR capabilities to try some DSTAR
satellite transmission as the AO-27 first DSTAR test in 2007. I
already have Robin AA4RC in my urcall list and i can see his amsat.org text
message passing in my screen!!! Just put my call sign in your
urcall list the next step is to find a common footprint. Just go on
http://www.ao27.org/AO27/index.shtml at the bottom of the page you will
have all you need to program your DSTAR radio parameters.
SSTV text chat and file transfer is also possible on DSTAR too.

Den Connors, KD2S (SK) (Sep 3, 2009) -- The first president of Tucson Amateur
Packet Radio (TAPR) Den Connors, KD2S, of Pepperell, Massachusetts, passed
away September 3 from lymphoma. He was 58. Connors, an ARRL Life Member,
conducted the first amateur packet radio contact with all-American hardware
and software, using the Tucson Amateur Packet Radio Terminal Node Controller
(TNC) with Lyle Johnson, WA7GXD (now KK7P), at 9:12 PM (PST) on June 25, 1982.
The tests were conducted at 146.55MHz, with both stations sending plain-text
ASCII messages. "Den was instrumental in the early PACSAT work, and as TAPR's
first president, led that organization from a local club he co-founded into an
international organization," Johnson said in an e-mail. "His was a very
cheerful, positive, can-do influence."

The amateur satellites are included. Once you load Google Earth and it in
turn downloads the data you can turn off those satellites you don't want but
first go to the bottom of the alphabetic data and un-check the debris,
rocket bodies and inactive satellites to reduce the clutter.

Oops, yes, you live and learn. Sometimes it's hard to guess which
scenario is going to be the most troublesome, when you first try your
hand at something new. I'm sure future APRS satellites won't have
this problem, thanks to your experience. And well explained too.

Right now the satellite is in constant illumination, so the 24 hour mode
change timer is working. It toggles the spacecraft between Mode A and Mode
B. I look at http://oscar.dcarr.org/ or
http://www.planetemily.com/ao7/ao7log.php for an up to the orbit
determination.

Luc those are good thoughts. I went to a mindset of more PCSAT satellites
with the SpaceX thing...but of course the theory is just a platform to carry a
small payload.
The small transponder you mention is indeed amazing.
I wonder as well if there are some opportunities with the Japanese in terms of
their transfer vehicle (interesting to see the differences between that
vehicle and the European one).
There are massive changes coming in "how" space is done in the US. If Falcon
1E and 9 are success...hang on to your hats.

FO-29 still has some trouble.
Therefore it is examination use for a while only over Japan.
We do not yet understand when it restore.
But there are the reception report from South America and Europe.
You may listen to CW with luck over your area.

Hi!
Thanks again to Ron W6ZQ for another Hawaiian grid on AO-51. Ron
drove not too far south of where he is currently staying on Kauai
(BL02), to put BL01 on the air on the 0246 UTC AO-51 pass. Robert
NH7WN from Honolulu (BL11) was also on the same pass.
I had a maximum elevation of 4 degrees for this pass, and was
able to work W6ZQ at just under 2 degrees elevation and NH7WN
at just over 3 degrees elevation. I think W6ZQ logged some
QSOs before I could hear the downlink, then I worked him and
heard him work 6 others before I lost the downlink. Robert was
also working a few stations during the pass, and I think Ron and
Robert worked each other for an inter-island QSO out there.
Thanks to both of them for making the effort to work us on the
mainland, and to the other operators for an orderly pass that
allowed for many QSOs!
Ron did not say when he would try to work the US mainland via
satellite again on his trip, but said he wants to get on again
at some other point this month from Hawaii. If I get any more
news from him on his plans, I'll post it on here. Robert comes
on from time to time, and hopefully he's getting more of an
assortment of calls in his satellite log in Honolulu (and, maybe,
some other grids).
73!
