I've got (2) EF Data SLM 8650 Satellite Modems from USAF ~ W |
|
|
I bought (2) EF Data Satellite Modems SLM 8650 at a govt.
auction. They were used by the Air Force. The govt. paid over $18,000
each for them. They can communicate with most major satellite systems
in the world. I've got lots of data about the modems, but I can't make
much sense out of it all. It can be used on DSCS II, SKYNET, NATO-III,
PANAMSAT, and all U.S. domestic satellites. Options extend the modem
range to include EUTELSAT and INTELSAT satellite networks. I do not
know if these modems have the options, but my guess is that they do.
What I would like to do is set one up for myself, and sell the other
one. Neither modem has been tested, because I don't know how to test
them. I'm swinging in the dark, and could use some guidance and advice
about what I have. I'm hoping that person reads this post!
Thanks for reading this...

Dude,
Just because you can "plug into" these networks does not mean that you
can access them. Each is a restricted access system and without an
account you basically bought a couple of paperweights.

Well, that's an eyeopener! Okay, so I won't be connecting to every
satellite, since I won't have access codes or accounts for them all.
But, are they completely useless? Is there any way to use them in a
limited function? How can I obtain acess codes? Any suggestions out
there for me? Thanks! |

OK, there is no account or access code to acquire with these modems.
These are used for SCPC (Single Carrier per Channel) and work end to
end. For instance, you use one to broadcast data from one satellite
terminal to another on the far end. They are not used to receive DVB
(Digital Video Broadcast) or DTH (Direct to Home) links. If you wanted
to simply receive communications links that are already in service you
would need an antenna with an appropriate LNB, and then you would need
the satellite, frequency, datarate, modulation, and coding used for the
link. Once you locked up on the link, you would need the correct
equipment to make sense of the data that you are now demodulating.
Data sent over a government SCPC link is encrypted. Data sent over
civilian links may or may not be. This data would be of no use to
anyone except for monitoring purposes. If you wanted to pay for
service, you could use one modem along with a VSAT terminal and
contract a teleport to provide IP service via SCPC, but there are
cheaper solutions for internet via satellite. |

dflywizzrd, thanks for taking the time to give me the info. Obviously,
I was hoping to put them to some use, but, thanks to you, I am now
certain that "billu" hit the nail on the head, these modems won't be
doing me any good at all. I'm interested in building my own setup for
satellite access (I've had DirecTV for years), and I thought I'd grab
these up on a govt. auction. I only paid $40 for the 2 of them, so I'm
getting a pretty cheap lesson. I am still interested in learning how
to handle my own satellite reception, but I know I've got a lot to
learn before that will happen. I'm hoping I'll learn something or two
from this forum. Thanks again for your imput. |
