Re: [Discuss-gnuradio] OP25 FSK4 Demodulator Error

[Marcus Müller]

Hi Brandon,

which version of GNU Radio are you working with (`gnuradio-config --version`)?
I'm not quite sure, but I think the porting of OP25 to GR 3.7 is still ongoing, so I'm not quite sure it's supposed to work with current GNU Radio at this point.

Greetings,
Marcus

I'm trying to get my OP25 flowgraph to work. I am having some issues with the FSK4 demodulator and the OP25 Decoder (Combined) blocks. When I run the flowgraph, I get the error "Exception: Could not find a FSK4 demodulator to use". This happens whether I use the combined block, or the FSK4 Demodulator and the simple decoder. I have gr-baz, and gr-op25 installed. In the python shell, I have tried "from gnuradio import fsk4" and I get "cannot import name fsk4". 

I did have to modify the op25.py file to point the import statement to the op25 library as discussed in https://lists.gnu.org/archive/html/discuss-gnuradio/2014-07/msg00293.html
