Re: [Discuss-gnuradio] Baudline sink ist missing

Hi Marcus,
a) Yes
b) Yes (i don't know how the preamble or synword or data my bell push are
looking that is what i want know too) here is a
protocol of it:

C) with a scope and with Baudline after the "complex to mag block" i can
detect the (0's and 1's) transferm like low and high.
it is three burst i zoomed so that you can see nearly the bit transfer.

when the scope sink is after the MM clock recovery i can also see the
transfern von low and high with Baudline too.But the transfer is slow i
think because the data_rate (19200) reduce the speed in the MM clock
recovery. But the Transfer is looking gut with baudline.

but i cannt zoom in i can only zoom out and it see like.

but when the scope sink is after the binary slicer i see nothing with
Baudline just

and i cannot conect the Binary slicer output with a scope sink.

Best regards
