Hi Marcus,

thanks, tried your script and found out, that it is always a little bit
uncomely if something is not really reproducible. This is the status:

With your script I did not get the earlier error anymore. However with
my original I did not get it either. Instead I get the following message
in GRC:
@@@@@ Sync State Detected
@@@@@ Lost Sync (Got 50 bad blocks on 50 total)

I do not get this message if I run your script. Both scripts though do
not show RDS information. So before I steal somebody's time I wonder if
one reason could be, that I can only receive one station really at the
limit and only if I set gain to a max. I can hear fairly clear audio,
but I am not sure if I can conclude from, that RDS decoding should work.
I am pretty much insulated from RF at my place. What would be in favor
by people being sensitive to EM waves, but for experimenting it is
pretty bad.

So I might gonna check this outside, where I can see in my car, that RDS
reception is working on my radio and then I can compare. Just want to
make sure we or you aren't chasing an error which might be based on poor
reception.

However the messages in the terminal have been there last time and the I
copied to also were there. Still don't no if this is part of the problem
though. Therefore probably more testing on my side.

Best regards,
Mike
