Hi all,
A couple of updates:
· gr-baz (git & SVN) now contains the fix to the issue regarding the ‘gruel_common’ compilation error (thanks Alex Csete).
· The OP25 block now first tries to use the op25.fsk4_demod_ff, and then falls back to fsk4.demod_ff if the former is not found.
· For those experimenting with OP25 and the RTL DVT-B USB dongles, I’ve started a Google Group for discussion surrounding the device, and its use with gr-baz/GNU Radio/plugin on Windows.
Regarding the error seen by ‘allanjs1986’ in GRC:
Type “msg” is not a possible type.
I’m a little worried about this – are you using the latest GRC? I thought message queues (specified by the ‘msg’ type) were still around… does anyone know more?
If you need a workaround, then just comment out/delete the last <source> block (name: ‘tune’, type: ‘msg’) in gr-baz/grc/op25.xml, do a sudo make install, restart GRC, and remember to set ‘Output auto tune’ to ‘No’ in the OP25 decoder block properties.

Hi all,
This is a known issue – unfortunately I just haven’t had the time to make necessary modifications (will do so now), but the temporary work-around is to symlink:
/usr/local/include/gnuradio/swig/gruel_common.i -> /usr/local/include/gruel/swig/gruel_common.i
The new version will be in the gr-baz repo hopefully very soon…
Thanks for the report,
Balint

Hi,
I've just tried building the gr-baz module on a couple of different systems but I'm encountering a make error along the lines of: ./baz_swig.cc: No such file or directory
I note someone else has also encountered the same error and pasted their make output to pastebin (http://pastebin.com/y6dUAxC1). This is the same error I'm getting. Anyone got any clues? Is this a generated file that isn't being generated, or a file that hasn't been included in the svn repo?
Thanks
Cheers
Richard

Ha ha, it's a pleasure to see this project move forward.
The cheapest one I've ever built was for $1.00 - picked up an old crystal scanner at a hamfest that happened to have a crystal in it on the proper frequency for a local P25 station. It only needed a disc-tap using parts from the junkbox...
