Global Satellite ground station system
by Bob Bruninga 02 Mar '08

02 Mar '08

> The Universities at Auburn, Iowa and Louisiana.. > need... a ground station in the southern hemisphere... Contact AMRASE organization in Brazil. They are building a an amateur satellite called CAMOES that may also support the APRS digiepating mission with either an uplink or a downlink on the 145.825 frequency. The more satellites and the more ground stations we accumulate, the closer we get to full-time round-the-clock hand-held communicatinos from anywhere on the globe. The beauty of having more ground stations is that they can operate with OMNI antennas and do not have any moving parts. They can link everything heard into the APRS global internet system for connectivity to anyone on the planet in real time.

Re: AO-7 Log

Hi Ron, Rgr ... Bob's a mate of mine ... like me, he's no computer geek so a bit of finger trouble is to be expected - no big deal. I administer and correct the log for a number of years but stopped several months ago - it was taking up too much time ... I was just pointing out that the ensuing accumulative errors over time will ensure the statistics page will be incorrect. 73 John. <la2qaa(a)amsat.org> Homepage <http://www.observations.biz> From: Rm2642(a)aol.com Date: Sun, 2 Mar 2008 00:37:10 -0500 Subject: AO-7 Log To: la2qaa(a)amsat.org Hi John: Just to comment about your post on amsat-bb about W7LRD and N6PAA QSO. There should be one log entry for our 01-Mar-08 QSO on AO-7. I don't know what Bob was thinking with the 3 log entries a few minutes apart. 73 and Thanks, Ron n6paa Delicious ideas to please the pickiest eaters. Watch the video on AOL Living.

Hi Amsaters The Universities at Auburn, Iowa and Louisiana are apply for a grant to build a cubesat and we need some one to host a ground station in the southern hemisphere at latitudes > 55 deg S. The orbit will be a polar orbit and locations in the higher latitudes will be in the foot print more time per day that us in the middle latitudes. We supply the hard ware for a fully automated station I.E. Icon 910, M2 antennas, rotator and a computer and we need a volunteer to get it in operation for us and connected it to the internet. We expect the life of the sat to be a year or two. If you have a interest please contact me off line thanks nick

Re: recent AO-40 efforts?
by G0MRF＠aol.com 02 Mar '08

Hi Auke / Don I believe in the case of AO-40, there is potential damage from a corrosive fuel 'leak'. Regarding battery protection. For smaller satellites an optically switched solid state relay between the battery and the satellite bus looks to be a good idea. Any time the battery has an EMF of greater than 2 volts the relay is 'on' and its MOSFETS connect the battery to the system. If the battery volts go below 2V then the relay goes 'open' and the battery is disconnected from the satellite allowing power from the BCR to go directly to the payloads. You could also send a command to switch the relay back on to recharge the battery at a later date. Would be nice to try all this some day. Several years of normal operation followed by several years of daylight only sounds good to me. Talking of daylight only....Hopefully only 6 weeks to the Delfi3c launch! 73 David Someone else my be able to correct my understanding if I have misunderstood the AO-40 design. Hopefully those who designed the power system have moved on and we now have some better insight.

Also, could the solar panels have fuses that have opened? could such fuses be re-settable? I would be interested to hear what knowledge there exists about the present status of AO-40, especially what "google" couldn't fetch.

ANDE-DeOrbit project closed: donation made to P3E
by Henk, PA3GUO 02 Mar '08

02 Mar '08

Now our ANDE-DEORBIT project has come to an end, and all requested certificates (up to now 51) have been shipped, we would like to make up the promise we made: "All of the left-over money to be spend on an AMSAT project". Many of the participants donated much more as the required printing & shipping cost. We have rounded the amount and made a donation of 150 Euro to P3E. Soon you should see the three new pixels "MAA" appear on the P3E website: http://www.p3e-satellite.org We would like to again say "thank you" to all that participated in the project. It was a great experience and we have made many new friends world-wide, that's HAM SPIRIT ! 73 and THANKS ! Mike, DK3WN Henk, PA3GUO http://www.ande-deorbit.com

Ft-736 problem
by randy 01 Mar '08

01 Mar '08

When i key the mike the needle does not move forward to indicate the power output level but instead moves to the left and bottoms out. I have set the drive output to various levels but it still fails to indicate power. I know it's putting out power because i can hit repeaters but it won't indicate it by the needle going forward. It goes in the opposite direction to the left. Any help will be appreciated., Thanks, Randy
