GNURadio ISM band transmitter data decode

Hello,
I am looking for person who has experience of signal processing using
gnuradio.
We have a radio transmitter that transmits data in format:
<PREAMBLE [4 byte]><SYNC [2 byte]><DATA [9 byte]><CRC [2 byte]>.
With the following parameters of a signal:

  • Frequency - 868.0 - 868.9Mhz
  • Modulation type: 2FSK or 2GFSK
  • Buadrate: 1Kbps

Rado data is received on a computer using a USB FUNcube Dongle Pro+.
Need to write a console program in C, C++ or Python programming language
using GnuRadio.
Program should listen to the airwaves in search of a signal. If the data
is found (<DATA [9 byte]>) display them to the console.
Also, the program should check CRC.

We can provide a raw radio data stream (file) with record of a signal.
Or remote access to our PC with a connected USB FUNcube Dongle Pro+
(transmitter will be located in close proximity).
