Inmarsat c decoder

The web page help file in the inmarsat c decoder demo shows a signal in analyzer 2000 that looks nothing like the display I am getting on inmarsat at 98 west around 1543.140 mhz. I wonder if somone could tell me how I should setup analyzer 2000 so I can eliminate that as why I am not getting the proper display.

I know quite some time has passed Paul but thanks for the reply. I did finally get the inmarsat software to work using analyzer2000 for tunning, the signal accually looks pretty good.

I have checked the decoder site quite frequently for a full version but no such thing. Is there going to be a full version or is it dead?

Hi Freewave,

In A2K you need to select the PSK tab first, that will bring up the PSK measurement / demodulator section. You should tune the receiver carefully, and if you are indeed monitoring a BPSK 1200bps signal, you should see the familier spectral pattern. You need to be tuning in SSB mode for this to work. If you are still stuck, visit us in the hearsat IRC channel, you can get to it by clicking the 'live hearsat chat room' link on the left.

 regards,

Paul.
