Thinking along those lines
Speaking for a "Non" satellite station point of view. I saw on here (I
think) that the power level was going to be slightly higher for the current
schedule. I have an FT-847 and a 6m/2m/70cms omni on the roof. I also have
a 2m/70cms pre-amp near the antenna. On a pass yesterday morning, I could
hear AO-51 reasonably well (when folks weren't keying over one another) so I
dropped my call-sign into a small gap. 4 contacts later (and one on the
next pass), I'm still smiling.
Looking for a cheap rotator now suitable to hold a small beam for VHF/UHF.
Actually I have a Mini-kits L-band LNA. Any pointers for a simple to
construct antenna?

WA3WUL has been working via AO-51 from Delaware recently.
He seemed to hear very well and worked quite a few stations
on this morning's pass at 1138z, 4 May 2010.
According to QRZ.com he is just north of Wilmington and just
inside the border about two miles from Concord Pike and Naamans
Road where I operated from in July 2009. ND9M/P operated from
several locations in Delaware prior to that and WD9EWK/P operated
from Delaware during the AMSAT Symposium in the Fall of 2009.
N3ZLL/M has operated in Delaware before and was worked via the
ISS in February 2009. I am not aware of anyone else operating from
Delaware over the past few years who actually lives there (until now).
For those working towards their WAS, be sure to listen for WA3WUL.
States that have activity now can become rare overnight. Wyoming
was very common when NN6T lived there; when he moved there was no
one on for some time. K7DRA became active and Wyoming was no
problem. Lately I have not heard him and Wyoming is now becoming
rare again. South Carolina was rare at one time. Now there are
many operating from that state including the very active K4YYL.
If you are working towards WAS, don't miss out on working WA3WUL
if you still need Delaware.

Hi All
A week late , sorry thought I had posted it here but heres the report.
Amsat India was invited to attended the Indian Small Satellite Systems
Conference -1 conducted
28 April 2010 , at ISRO Bangalore.
Amsat India was represented by Ganesan ( our Hamsat 2 designer) and myself
VU2POP
ISSSC was a one day programme from 9 am to 5.30 pm .
It was very interesting and as many papers were presented & topics discussed
the time was short it got over by 7 pm.
One day is too short and hopefullu next year it will be 2 days.
However we thank ISRO for kickstarting a very interestng platform for
interaction of ISRO with various educational institutions including Amsat
India who are into ham satellite projects.
Important topics were on the current Small satellite develpoments and the
future trends of small satellites including Mini, Micro, Pico sats etc.
Hamsat VO-52 too falls into the small sats, to add many students all over
the world have been building student sats as projects and in India too,
nearly 26 Universties have got into building student sats with various
payloads.
Most Ednl. intitutions already have a ham club and some institutions are now
setting up ham clubs in their institutions to help learn more of ham
satellite operations and facilitate building ham band payloads.
As of now most of them are either digital with only beacon downlink and no
voice transponder.
In the next couple of months you will find many cube sats etc with
experimental payloads launched.
Amsat India has 2 linear tranponders ready and we Amsat India are asking
ISRO for a higher orbit to cover a larger foot print and longer pass
duration.
Its no use having another LEO as HAMSAT 1
Hamsat 1 will be celebrating its 5th birthday on 5 May and ISTRAC has been
monitoring its health and its utilisation, they report that Hamsat 1 is in
good health and should serve the hams for many more years.
In this regard there was an email by VU2WMY Mani a few days ago asking for
USER feedback like utilisation & experiences by hams all over the world with
Hamsat 1
Please send in your reports , utilisation and experiences with Hamsat by
email and the same will be forwarded to ISRO.
Looking forward to all your reports comments.
We would like to thank ISRO for the HAMSAT 1 and we look forward to HAMSAT 2
Finally we thank Programme Dir and Project Director - Small Satellite &
Uppagrah Amateur Radio Club for the kind invitaion to particpate in the
ISSSC-1 and we look forward to many such platforms for the development of
small satellite systems with the participation Educational Institutions &
Amsat India.
Best regards
Pop
VU2POP
Dir Technical
Amsat India
Hams who attended VU2WMY, VU2GDX, VU2RVJ, Ganesan , Chandraskar new hams &
myself VU2POP.

Diana Eng KC2UHB has developed an ingenious antenna for satellite working.

Presumably that's because very few people have L- and S-band equipment.
I'm guessing that many people are - like me - put off by the prohibitive
cost and requirement for overcomplicated tracking systems.
Working V/U with a handheld antenna is much more fun than sitting
watching a computer twiddle servos and tune the radio for you.

I work V/S with two HTs, and a ~10 inch corner reflector and
downconverter for S band. One HT has a $10 MFJ whip, and the other is a
IC-2 purchased for $5. I bought my last 2 downconverters on Ebay or
hamfests for less than $20 each.
Sort of like Mark is doing here:

It's not tough...and lot's of fun.
