I'm using the freq message output of the QT GUI Frequency Sink to drive the freq message input of the Frequency Translating FIR Filter. Since I have set the the Center Frequency of the QT Frequency Sink to 7E6 Hz, that means I need to subtract that value before I send it to the channelizer so it only falls between -Fs/2 and +Fs/2.
I tried converting the message to float via PDU to Tagged Stream but that does not work: thread[thread-per-block[1]: <block pdu_to_tagged_stream (8)>]: pmt_length: wrong_type : 7.12348e+06 Is there a proper way to do this, i.e. convert to float, add the offset, and convert back to message? Or is there a way to do this within the Xlating FIR Filter center frequency field.
