OK sorry folks - this is what one should expect when they're dealing with ancient code (I really ought to update at some point!).
I've fixed the gr-baz/python/op25.py code to first try the new OP25 blocks (with the slicer), and then fallback to the old version (without the slicer).
Let me know if this works! Thanks, Balint
Hi,
I haven't encountered that error message before myself. Is that in a GRC flowgraph you fashioned, or when you run the sample one I have the gr-baz/samples directory?
That block output (with the 'msg' type) must be used with the Message Callback block (also in gr-baz) to handle auto-tuning messages sent by the FSK4 demodulator. Alternatively, you can choose to switch off that output port in the OP25 decoder block's properties.
Hopefully that helps - let me know!
PS: Regarding running audio_p25_rx.py, I have in the past used some variant of:
sudo ./audio_p25_rx.py -a -I hw:1,0 -g 15
'sudo' was necessary for creating the 'tun' device so I could capture frames in Wireshark. '-I hw:1,0' was to select the second (non-default) sound card (you could leave this off if using the default), and '-g' would have been for the gain. YMMV!
I believe there is another example of a full command line you could specify on the OP25 wiki. (You can also just put an '-h' on the end to explore the available options.)

Hi thanks in the op25 decoder block in GRC there is an error msg
Source - tune(2):
Type "msg" is not a possible type.
And how the hec do i run the ./audio_p25_rx.py -a command in terminal If you cant tell i am a complete noob.
Hi it comes from the sample op25 flowchart. [IMG]http://i43.tinypic.com/6h5837.png%5B/IMG] [IMG]http://i40.tinypic.com/534g8p.png%5B/IMG]
