Re: Two satellites passing in the night.... or day.

Thanks Patrick, You and Joe Lowenthal had the same idea and it works for me. I will make sure that the PL is off and work AO27 only and see how it all flies. Pass time is for me AOS about 2000Z on the 11th of Feb. AO-27 turn on will be about 5 minutes later. It will be a somewhat west pass so hope to be able to work you as K2BSA/5. There is a point mid pass where the two birds will be pretty close together. One benefit is that SO-50 runs 5-10KC lower than published so that also might help depending on where the dopler shift is at the time.

This happens periodically, and there's not much you can do about the downlink. You hope for the two satellites to be in different parts of the sky, so you can point away from one satellite enough to clearly hear the other. The uplink is usually a bigger issue, but you can at least know one thing - if you transmit without a PL, only AO-27 will hear you. If you transmit with the 67.0 Hz PL tone, you could potentially be heard by both satellites. Depending on how the two satellites are passing by, I usually try to work AO-27 in this situation. It's only on for 7 minutes, generally hears stations better than SO-50, and its downlink has twice the power (500mW) of SO-50 (250mW). Transmitting without a PL ensures you are only going to be heard by AO-27. Once AO-27 shuts off, then I can turn on the 67.0 Hz PL tone and go for SO-50. Good luck, and 73!

I wonder if some of the folks that use the birds even read this list.. Because there sure are a lot of them who appear not to know what the heck they're doing and how to work stations. 73, John, K6YK On Wed, 25 Jan 2012 14:24:02 -0500 "Craig Gagner" <crgagner(a)charter.net> writes: > You can go to http://www.livestream.com/w1msgsat and under latest > videos the > AO-27 pass is listed from today at 1810 UTC ..

Re: SumbandilaSat beyond repair????

According to the original report from Defence Web theprimary pay load is no longer usable. Later in the news bulletin Rob Olivier from SunSpace says that “radio transmissions still operate, making it useful to radio operators around the world, including in the US, Europe and Australia” There could be hope for us yet! May be someone from Amsat-SA can clarify the status of the Ham Radio pay load. 73’s Mal – VK2MAL.

Hi all... I tried to manually put the New Keps for RS-39 into Orbitron and also wxtrack and the Sat does not show up in either program... Is there something...even minor maybe wrong with these Keps...

Keps can be found on this website: http://chibis.cosmos.ru/cyclogr/prepare1/google/index.html Up in the left corner you can see two small gearwheels. Just click on them and in the appearing menu you will see the title Satellites. Choose RS-39ch and the latest keps will appear. gl de ha6nn Andras

SumbandilaSat beyond repair

South Africa’s second satellite, SumbandilaSat, is no longer fulfilling its main purpose due to technical problems and is essentially beyond repair, its maker SunSpace says. http://www.uk.amsat.org/4076 73 Trevor M5AKA

Barrow Alaska (or other alaska) stations?
by Bob Bruninga 25 Jan '12

25 Jan '12

We will be floating a buoy with APRS transponder from Barrow Alaska in March. Any hams up there to listen to it directly before the ice melts? Then after it begins to drift, we will need AMSAT hams anywhere in Alaska to capture any packets on 145.825 via ISS. The ISS gets to 1.5 degrees elevation once a day up there. If you know someone not on this list, can you pass this along? Bob, Wb4APR
