[amsat-bb] Re: Arissat bpsk1000 software?

[Gould Smith]

Hello Jeff and BB,

The BPSK-1000 downlink is transmitted in SSB mode. I sounds like a 
"shusssch", higher pitch than the 400 bps growl. It is difficult to tune by 
ear. So the CW signal was moved close to it so the CW signal could used as a 
tuning signal.
Plug  the audio from an SSB receiver into the computer soundcard MIC/LineIn 
socket. The PC//Mac software display contains a dotted line that you use to 
tune your receiver until the CW signal bump lines up with the dotted line 
and the software will decode the BPSK-1000 signal as well as the CW.
The BPSK data is composed of 5 packets.
TLM
Experiment packet 1 of 5
TLM
Experiment packet 2 of 5
TLM
Experiment packet 3 of 5
TLM
Experiment packet 4 of 5
TLM
Experiment packet 5 of 5
TLM
Experiment packet 1 of 5
...
We will have more about this as the developers get the first version ready 
for people to look at, we hope soon.
We will also have an Internet data stream running for people to practice 
using the software.

73,
Gould, WA4SXM
