[amsat-bb] interesting matters on the web

Though the Delfi C3 project has already mentioned their photo weblog here,
I thought it was worth mentioning that additional material is appearing
there quite frequently, showing the computer interface checkout, mechanical
fit test, and others. http://www.delfic3.nl/photoblog/ I believe this is a
very important project for the future of amateur analogue communications in
LEO because alongside other projects, its low-cost cubesat form-factor
houses a linear U/V transponder.  

The most recent (June 2007) Amateur Logic video webcast includes (near its
end) a short how-to on installing N-connectors on LMR400 cable. The
presenter hacks his own crimping device using vise-grips and a bisected hex
driver of some sort. I have to confess I have been buying expensive runs of
pre-built cable because I know I'm terrible at installing N-connectors. I'd
be interested to know what experienced installers think of this technique,
and how it compares to other methods. http://www.amateurlogic.com

I also wonder if there are special, amsat-related building or operating
skills that might well be recorded in video for broadcasting on that show
or just posted on YouTube for all to see. For example, to pick on a fellow
Canadian, by my count, Clare, VE3NPC, has built 1000 helix antennas. A
video showing his well-established construction techniques would really go
a long way to helping others undertake such a project. I'd personally love
to see a video of the operations of some of the fantastic cubesat operators
out there, like Mineo, JE9PEL, and Mike, DK3WN. Just a thought. In any
case, I think  Amateur Logic illustrates that competent presenters  provide
a great deal to their audience and are much loved, even if the video is not
yet ready to be broadcast on the BBC.
