Re: Oldest working orbiting satellite? Todays, quiz!
by Joe Leikhim 04 Nov '10

I got my first taste of satellites listening to ATS-3 with a discone, wideband tower mounted preamp, and Regency MX-3000 receiver back in about 1984. There were continual round table discussions by the Bahia from places like Roatonga. 135.575 MHz I recall. Does anyone else recall this traffic? Is it still going on? From that I started hearing various channels of Fleetsatcom between 250 and 270 MHz, loud and clear with the same setup. > >"The record holder appears to be ATS-3 still nominally operational after an > >amazing 41 years!"

I know this has been kick around before, however, w ith all the satellites up there in various stages of functionality is it not possible any of them could be "configured" for our use? 73 Bob W7LRD Seattle ----- Original Message ----- From: "Chris Bloy" <chris(a)photofuture.co.uk> To: amsat-bb(a)amsat.org Sent: Thursday, November 4, 2010 9:43:20 AM Subject: [amsat-bb] Re: Oldest working orbiting satellite?

Odd Split setup on TM-D710
by Jeff Yanko 04 Nov '10

04 Nov '10

Hi all, I have a TM-D710 that I use for various communications, including satellites. However, I am having one heck of a time trying to get it setup so that I can at least make an attempt to work NA1SS, the space station. It uses an odd split frequency scheme but I haven't been able to set it up for such a split. I follow the instructions in the manual and still to no avail, so I'm pretty sure I know I'm getting it wrong. Please contact me off -bb and any help will be greatly appreciated. 73, Jeff WB3JFS

Re: Questions about use of PC104 connector for CubeSat
by Ryan Caron 03 Nov '10

03 Nov '10

I'd suggest taking a look at AstroDev's He-100 offering, which uses the PC-104 card connector. http://www.astrodev.com/public_html2/downloads/datasheet/HeliumUserManual.p… Page 7 has the pinout, Page 20 has placement I would hesitate to use a board quite as large as that though, as it is highly optimized for the CubeSatKit, making use in other chassis difficult. I would suggest a slightly smaller board in line with Boeing's CS82 board factor. Slide 6 from this year's CubeSat Developer's Conference @ Cal Poly http://www.cubesat.org/images/cubesat/presentations/DevelopersWorkshop2010/… Are either of these the golden standard? Not exactly, but it is the closest thing I've seen to one. Ease of integration and flexibility are the key to getting your transponder flown. 73, Ryan Caron KB1LKI On 11/3/10 12:00 PM, amsat-bb-request(a)amsat.org wrote: > Message: 7 > Date: Wed, 3 Nov 2010 09:30:17 -0700 (PDT) > From: William Leijenaar<pe1rah(a)yahoo.com> > Subject: [amsat-bb] Questions about use of PC104 connector for CubeSat > boards > To:amsat-bb@amsat.org > Message-ID:<844462.5173.qm(a)web31801.mail.mud.yahoo.com> > Content-Type: text/plain; charset=us-ascii > > Hello AMSATs, > > Work and home situation kept me away from having any ham time.

Hi William >From my experience you can get a very good start by downloading the data sheet on one of the EPS modules from Clydespace. Lots of cubesats start by using these power systems and there are many products from other suppliers based on this pinout. The data sheet will tell you which pins are used for which function, but I dont recall seeing a diagram showing the position of the connectors relative to the mounting holes etc. My effort at a simple cubesat board based on the Clydespace EPS pinout is at: _http://funcube.org.uk/WP3/?page_id=195_ (http://funcube.org.uk/WP3/?page_id=195) As you can see, there are plenty of free pins !!

Questions about use of PC104 connector for CubeSat boards
by William Leijenaar 03 Nov '10

03 Nov '10

Hello AMSATs, Work and home situation kept me away from having any ham time. But recently I had some time to continue with upgrading my LE005 transponder design with a PC104 connector (or is it PCI-104 ?), and some other features ;-) The PC104 is a good choice for having a standarized inter connection system on CubeSat projects. However, I seen some deviation in the placement standard of this PC104 connector. >From the following website I read: http://www.cubesatkit.com/content/electronics/bus.html "The CubeSat Kit Bus utilizes the same physical connectors as the industry-proven PC/104 bus, but in an alternate physical location so as to avoid unintentional damage to PC/104 or CubeSat Kit modules." With my focus on: "...in an alternate physical location..." I would like to know what this possition is, and if this is now "the golden standard" in CubeSat world ? My next worry will be the pin configurations. Is there any standard for CubeSat boards ? Next I would like to know how modules are controlled by the data bus. Is it like separate pins for PTT, TX, RX etc... Or with more smart communication with lines like: address bus, data bus, Clock, Interrupt lines etc. (similar to old ISA PC cards) Or maybe with I2C. I keep it to these questions for now... Next questions will follow out of the answers hihi... 73 de PE1RAH William Leijenaar ---
