ARRISat-1 is visible again
by Mark L. Hammond 17 Dec '11

17 Dec '11

Okay, the predictions were right on the money. Just collected and sent 30 frames of telemetry from ARISSat-1. We North Americans need to take advantage of the improved visibility... 73, Mark L. Hammond [N8MH]

E1P Data Submission
by Carl Rimmer W8KRF 16 Dec '11

16 Dec '11

For those of you who, like me, have been copying and submitting telemetry data for the Explorer 1 Prime MSU project and may have found you are unable to submit data, I have received a response to my inquiry regarding that problem dated 12/15/2011: <snip> We are in the midst of a server upgrade and are doing a migration of the data submission services. They will be offline for a couple of days and then should be ready to go after that. Sorry for the inconvenience. We do still request telemetry submission and thank you for you patience. -Ehson E1P Program Manager </snip> Merry Christmas and Happy Holidays to all my AMSAT friends. 73 -- *Carl W8KRF*

PicFall transmisson via ARISSat linear transponder
by Roland Zurmely 16 Dec '11

16 Dec '11

At orbit # 2112, almost vertically from my QTH, I did a PicFall transmission, with only 18 W in a 6 element UHF Yagi. This transmission was converted from UHF to VHF by ARISSat linear transponder. See the result in received spectrogram on VHF with a DCA antenna and home made VHF to HF converter, and a SDR-IQ controlled by SpectraVue, here: http://www.qsl.net/py4zbz/arissat.htm#s 73 de Roland.

Satellite Stations in Alabama
by Kyle Owen 16 Dec '11

16 Dec '11

After the launch of AubieSat-1, now AO-71, many stations across the world were able to pick it up. However, it's very weak. Our 100W station at Auburn University has been unable to command it, which has led our team to believe that the antennas did not deploy. However, there is a chance that with enough power we can at least get a few words from the satellite. I have tried contacting Dennis Dease and Jimmy Long in Alabama, but neither have the equipment set up to talk to satellites. Would anyone in the Southeast US area be able to help me get 1.5kW pointed towards AO-71? I have the command transmitter and a 100W amplifier in my possession and would need to be present to talk to the satellite. The uplink and downlink frequencies are both in the 70cm band. I would be looking at doing something within the next few weeks since I'm home in Birmingham. Thanks, and 73! Kyle, KK4ANG Chief Engineer, AubieSat

Looking for Simple SDR schematics for homebrew
by Raidel Abreu Espinet 16 Dec '11

16 Dec '11

Hello everyone, I am looking for a simple and easy to build schematics for a SDR reciever in a fixed frequency of 10.7MHz because I am looking to feed it with my reciever 10.7 IF output. I search a little over internet and found a lot of very complex design and the easier ones are by kits offereds for sale which cannot be deliver via postal mail due my local customs regulations. So I'm looking for something simple and easy to build with not too exotic components. If someone have some advice and recommendations, please send me an e-mail. Also if some of you know about a cheap for sale kit which is currently on stock with a really fast and short deliver time let me know, I have a friend visiting some relatives, and he is returning in the next few days. Thanks, Raydel, CM2ESP, EL83 --------------------------------------------------------------------------------------------------------------------------------- Este mensaje ha sido enviado mediante el servicio de correo electronico que ofrece la Federacion de Radioaficionados de Cuba a sus miembros para respaldar el cumplimiento de los objetivos de la organizacion y su politica informativa.
