[Discuss-gnuradio] autonotch filter with probe_signal, function_probe and band_reject_filter |

Hello,
i'am trying to build an autonotch-filter for shortwave with GRC.
For this i'am using an "PLL Freq Det"-block, and an "Moving Average"-block.
For testing, there is a 900Hz signal added to the signal.
Behind the "Moving Average"-block is a "WX GUI Number Sink",
which show's, that the PLL has locked on the disturbing 900Hz-signal.
My attempts with "Probe Signal" and "Function Probe" dont work.
The value of fnotch in the filter does not update.
How can I use the "Function Probe"-value to update the "Band Reject Filter"?
The flowgraph is under http://www.imalsta.de/grc/m80.grc

Maybe someone can tell me, where the mistake is?
Alex
