-
- Did anyone else manage to work anybody through AO-13 on Field Day?
-
- We heard the beacons loud and clear but the transponders were
- absolutely silent. Was this just a case of a really bad squint angle
- or was there something else going on?

-
- Not really. The commented source code needs to be made availeble so that
- programmers don't have to re-invent the wheel to add functions to the unit.
- > Is firmware version 2.0 the latest?
-
- Yes, and I have not seen any word of further upgrades in the immediate future.
-
- >Is the AEA DSP unit programmable
-
- Yes, but unlike the Grace unit, AEA does not encourage outside development.
- This means that all improvements are written by them ONLY. It took them well
- over a year just to get the step outputs working for the PSK Pacsats...
-
- > and if so are programs written for it compatible with the DSP-12?
-
- Unfortunately, no. Although they do use the same DSP chip (56001), their
- control processors are completely different, as well as their underlying
- operating systems.
-
- I have been using the DSP-12 for three years now, and I thoroughly enjoy it.
- If I ever get some time to play with it, I would love to do some programming
- with it. You can't do that with the DSP-2232...

- Subject: Element Files Standard
- To: ham-space@ucsd.edu
-
- Over the years, I seen a lot of different ways of elements being sent. They
- seem to have boiled down to two types, Amsat and Two line. This is fine, since
- most tracking programs will read both, but there seems to be no
- standardization for filenames.
-
- This makes it very difficult for programmers and users alike to find these
- files when it comes time to update. Since this is done as often as 3 times a
- week or more, I think that there should be some sort of standardization for
- the filenames used.
-
- I won't go into what I have been thinking of, since I would rather hear
- completely fresh opinions, unbiased by my suggestions. I have had a few
- responses on the two Kitsats where I posted a similar request, but I want to
- hear from as many as possible before throwing out a proposition.
-
- Filenamse are not the only problem. Usually there is extraneous text included
- in the files. This text, though sometimes informative, is enough to drive a
- programmer to take up knitting instead! If anyone has ideas on how to separate
- this extra text, while preserving useability, I would love to hear it!!!
-
- I will be checking this area for about a week before I formulate a
- proposition, which I will send out for comment, and then present to Amsat,
- NASA, and whoever else might help in implementing a standard.
-
- Here's your chance to make a difference! Let's hear your ideas!!! Post 'em or
- mail 'em, or send them via KO-23 or KO-25....

- For some time now I wish to get started into Satellite communications,
- Reception at first, but I'm somewhat lost :-(
- What Satellites are able to be used over Europe ?? What kind of antenna
- can be used, other than the parabolic antennas ??? What bands are available
- for Satellite use ??
- I'de really appreciate a reply via e-mail...
