Anyone mess with this issue? Mine was one of the threads for alternative center scale for 5400. I created mine by taking the scale off the meter, scanning it at as higher res as I could. I loaded the BMP ( preferred to jpg because of losses in compression) into Paintshop Pro, re-lettered it with the appropriate figures and airbrushed the scanning blemishes. I printed it onto a self-adhesive label ( took several attempts to get size exactly right) and stuck it on the back of the existing scale. couldn't tell it from the original. Hope this may help. ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member? Join now to support the amateur satellite program!

I just lashed the setup together so maybe taking more care to isolate the converter from the TS-2000 might improve my results. I'll have to give it a try again. Mount the down convertor at the aerial/masthead! way out of range for the spurious and you can use cheap cable for the 10mtr down feed line! ___ Sent via AMSAT-BB@amsat.org.

We've been given a licence to transmit and will be testing our re-engineered ground-segment in the next fortnight. The passes we are going to concentrate on will be as far out west as possible, as to minimise QRM from Europe. Earth is a lot more EM noisy than it was in 1971. If anyone in the UK wants to try and tune in to the downlink, you can help ID any response we get from the old bird. The passes are summarised here: The Prospero Satellite was featured in a BBC program called Coast It was in the program BBC.Coast Series 2 Episode 1 Dover to Isle of White. It shows an attempt to receive the signals, which appeared to be successful, showing the frequencies on the AR2000 ( I think) RX. I have that episode, and have extracted the section that deals with it, you can get it ( 9.5Mb .avi) at http://www.taghill.co.uk/dmf/files/prospero.avi The entire program also deals with the research into the propellants, and the launch from Australia, but is far to big to upload!

[amsat-bb] Re: Adjusting true north for azimuth rotator.
At 21:42 03/09/2011, you wrote: I am planning to install my G5400 rotator inside a tower having a welded rotator shelf. The tower is not installed yet and will have one face against the side of my house which is positioned about 28 degrees northeast (Per Google Earth). I assume when I drill the rotator shelf, I can adjust for the gross 28 degree offset of the tower. However how important is it to do this at all? Does the rotator have to be installed exactly toward true north or can I make up the difference when clamping down the antenna mast assuming the antenna is oriented true north? Note I will be using a Trakbox and need the ADC to center on true north. Surely it matters not how the rotator is mount, you just clamp MAST so that the antenna are north pointing, the orientation of the physical rotator is unimportant. ___ Sent via AMSAT-BB@amsat.org.

[amsat-bb] MediaWiki Trial

For those interested in timeframe, it took thirty minutes to configure this instance from a clean arch linux installation. If you are interested in poking around in the environment to see what it feel like, go ahead, that's why I set it up. I disabled email registration, so anyone can just create an account and get a feel for creating pages / editing / preferences / etc... Tonight, i'm going to hack at creating my own skin, since it would just be cool :-) I added the amsat logo to the main page for testing, I hope this doesn't violate any copyright rules If it does, hollar and i'll remove it. For the record, I have nothing to do with Amsat right now, outside of being a first time member this year. I also don't want anyone to think that i'm pushing for media wiki or anything of the sort. I just like the idea of having a wiki. I read the email thread and figured it'd be worthwhile to set an instance up so Amsat folk could get familiar with it. I have managed two other wiki systems on my own, trac / moinmoin. MediaWiki has quite a bit to offer and is reasonably easy to configure. Here's a link to the playground: http://71.43.22.149/ Let me know if you have any comments or questions (or if you get any weird behavior). Thought I'd start this as a new thread. Just been on the Wiki, I think its a great idea. I added my comments in the discussion section just to get a feel for it. I'm not an Amsat-NA member, but non-the-less think I'm allowed to comment.
