And we (the operators) won't be learning anything new. But instead folks are promoting an anachronism. They're discussing learning something new at the same time saying we should be using a technology that has been in use since the 1960s. So then instead of focusing on linear transponders how about deploying HSMM nodes into space, TDMA, or DMR technology? (No idea how feasible any of of this is) DMR as it stands isn't viable because it relies on really tight timing in the slots - the book figure is 75 miles but people have pushed it to over 100. The trouble here is that the speed of light just isn't that fast ;-) In any case, the challenge has changed. I don't see any real challenge in the hard sats, because the hard sat brigade all seem to use massive aerial arrays, with computer-controlled steering and tuning. I don't see what's hard about it - it's just throwing technology and no real skill at the problem. Once you've figured out the mysteries of the crappy proprietary software that people use to steer the aerials and tune the rig, it's point-and-shoot. The FM sats can be worked with something as simple as a dual-band handie and a homebrew crossband pair of Yagis - and a great deal of operator skill. No, the challenge today is this - are you ready? The challenge is: Get something flying, for less than the GDP of a small nation. There, I've said it. It's down to money. You know what else I'm going to say? There is almost certainly never going to be another amateur HEO satellite. There, I've said *that*, too. Want to know why? Because we're a tightfisted bunch and no-one is going to fly us for very nearly free. The HEO crowd have some amazing technology, but it's going to cost a fortune - a very large fortune - to fly these Death Star-sized satellites *at all*, never mind into HEO. The future is small satellites, where we will have to cram as much radio into a tiny cubesat payload as we can. Even then it's going to be expensive, so we're going to need to look at countries that are developing their space programme to get launches - and that's going to be India, Pakistan, Iran if they get their shit together, maybe Israel if we can get them interested in anything other than observation satellites and probably one or two others. Maybe some wealthyish African countries will get in on it, like the DRC or Kenya. We're going to have to try coming up with clever satellites, rather than flying a bent-pipe box the size of a fridge. No-one is going to want to lift that, without us paying full price. -- Gordon JC Pearce MM0YEQ ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

[amsat-bb] K2BSA/5 on satellites for JOTA
The National Scouting Museum in Irving Texas will again be making Satellite contacts as we can on Saturday, October 20 the for Scouting's Jamboree on the Air as K2BSA/5 Passes however will be limited if AO-27 is still out of commission. Will try FO-29 and AO-7 if in B mode. SO-50 will be too late in the day for us.Hoping that by next year we have FOX up as well as FunCube and UKCube for linear transponder options. No matter what, look for Scout stations and give them a call.

Hi Gus, 8P6SM I agree with you ! Unfortunately there is now a huge trend to build more and more of these shoe boxes (CubSat) to fly around earth. I would not call them satellites, because just a box with some solar panels does not make a real satellite. As we see, most of them are almost useless, in particular for the ham satellite community to communicate and they are a waste of money and resources. It's more like a prestige object for many Universities and their Professors. What kind of science is it, to buy a ham radio hand held and modify it for use on a shoe box ? The wheels are re-invented again and again... For us AMSAT'ers.. this is something we did almost 30 years ago This is history and nothing like science anymore... Instead it would be indeed better to build a HEO with advanced capabilities, but no one seems to be interested in it... At least AMSAT-DL is working hard to get P3-E finished and launched soon, but the mass flood of these CubeSats and other Nanosats makes it indeed more difficult. 73 de i8CVS Domenico - Original Message - From: Gus 8P6SM 8p...@anjo.com To: Gordon JC Pearce gordon...@gjcp.net Cc: amsat-bb@amsat.org Sent: Thursday, October 18, 2012 4:28 AM Subject: [amsat-bb] Re: OH2AUE P3E transponder demo video On 10/17/2012 05:38 PM, Gordon JC Pearce wrote: We're going to have to try coming up with clever satellites, rather than flying a bent-pipe box the size of a fridge.

Wow, a narrow self centric view of the world: a huge trend to build more and more of these shoe boxes.. ... most of them are almost useless... What kind of science is it,... The wheels are re-invented again and again... For us AMSAT'ers.. this is something we did almost 30 years ago This is history and nothing like science anymore... Please do not speak for me. Obviously the writer above has no clue what education is all about. Guess what! Every single year, the teacher has to start EXACTLY back at square ZERO. That is what EDUCATION is all about. Teaching each new year of students the same thing over and over and over. Its not fun... but it is challenging... Now I do not defend all repeats of stupid ideas and other mistakes, but education is a repeating process every year by definition. Now, if you want a different satellite built , THEN BUILD IT. It does no credit to lambast at least those that are DOING SOMETHING... even if it is not what you want, then either build what you want, and launch it, or get out of the way I have not been following this thread at all. So if my comments are inappropriate, I apologize. But some people have no clue what it takes to educate a completely new class starting over every year. Bob, WB4APR ___ Sent via AMSAT-BB@amsat.org.
