Hi Larry, 

Do you have the correct sound modem?


Use the ssb modem, 1600 main frequency in the spectrum.

Radio in usb, agc off if possible (or fast), no noise blanker/reduction.

You should receive the packet when the signal is within the bandwidth bar you see in the sound modem spectrum.

Adapt the DCD threshold accordingly, usually by the half.

In the green cube GUI window you should see the decoded packets, in the sound modem the data

What software is required to send and receive messages via the GreenCube sat. I’m currently running SatPC32 on Win 7.  I have tried Uz7ho soundmodem . I can see and hear the signal on the waterfall but no decoding. Is there additional client software that i need to download or setup procedures or links i need to follow. Thanks for the help! 73
