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 <http://www.imalsta.de/grc/m80.grc> Maybe someone can tell me, where the mistake is?
