[amsat-bb] Re: Two hundred 437 MHz satallites launch March 16 + WebSDR
As I see it there's no absolute guarantee that any satellite won't become an orbital hazard at some point. The debris from weapons testing in space can generate hundreds of thousands of fragments but the biggest hazard is natural debris - there are tens of millions of natural debris fragments in Earth orbit. 73 Trevor M5AKA On Tuesday, 4 March 2014, 2:06, B J wrote: On 3/4/14, M5AKA wrote: > Launch of Two Hundred 437 MHz Satellites > http://amsat-uk.org/2014/03/03/launch-of-two-hundred-437-mhz-satellites/ > > Southampton University Wireless Society WebSDR Tracks LitSat-1 > http://amsat-uk.org/2014/03/04/southampton-university-wireless-society-websdr/ > > RSGB: IARU 2014 VHF/UHF/UW Consultation > http://amsat-uk.org/2014/03/02/rsgb-iaru-2014-vhfuhfuw-consultation/ > Considering that space debris is a major concern, what guarantees are there that some of these birds won't become orbital hazards?

[amsat-bb] LitSat-1 candidate object
Based on a high elevation pass (82 deg) with satellite rise over the Pacific, 1998-067EM (39568) is a very good fit. AOS was within 10 seconds of predicted AOS. Doppler correction tracked good through TCA. 73, Ken W7KKE Lincoln City, OR ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

Is CDMA an authorized emission type for the Amateur service? What is the chipping rate/bandwidth of these? Don't the PRN sequences need to be made public so as not to be classified as "encryption" ? Detailed specs on the Sprites is in short supply. Has anyone done a link budget, seems like allot of spreading gain is required to hear 10mW form a 300km orbit which translates into allot of bandwidth in a part of the band usually reserved for narrow band modes. The lack of transparency on many of these projects that use the amateur bands seems to run against the spirit of amateur radio in my opinion. Howie AB2S ___ Sent via AMSAT-BB@amsat.org.

Yes, that is true, so are these licensed under an authority other than amateur radio ? If they aren't then my questions stand.

[amsat-bb] Re: LituanicaSAT-1 - Lithuanian CubeSat
If I understand the situation correctly they didn't send the first command to LitSat-1 until today at 15:30:26 EET. I would image they will want to be confident in the operation of the satellite before activating the transponder - I'm looking forward to it whenever it happens. 73 Trevor M5AKA On Tuesday, 4 March 2014, 20:55, VK2MAL yahoo wrote: Hi every one Any updates on the Lithuanian CubeSat?

[amsat-bb] Faking a software TNC as hardware
I am trying to use an application that expects a hardware TNC on traditional serial port. At this point in time I don't have a hardware TNC connected to my satellite station. I do have a traditional multimode TNC I could utilize but I prefer not. I am looking for a way, if possible, to configure a soft TNC application to pretend it is a traditional serial TNC. Essentially, the soft TNC would respond as a COMx,8N1 TNC just as if it were hardware. Is there a way to do this? 73 Clayton W5PFG ___ Sent via AMSAT-BB@amsat.org.

[amsat-bb] Re: LituanicaSAT-1 - Lithuanian CubeSat
I am not sure we are talking about the same bird Trevor. Is LituanicaSat-1 the same as LitSat-1. I thought they were 2 different satellites? I was asking about the one built by the Kaunas University of Technology "LituanicaSat-1". This bird is the one that has the FM transponder, FM CW beacon and AX.25 FM Packet radio as well. I see Mike DK3WN reporting briefly on the 2nd March reception of telemetry http://www.dk3wn.info/p/?p=42452 There hasn't been much more in the press on the satellite. Any way guessing others may report when things are happening. Thanks Malcolm VK2MAL 73s ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?
