If you are using an "if" statement to switch between filename and /dev/null,
try putting the filename construction in the "if" statement, instead of a

is called.
My example used the LO frequency as part of the filename, an

Any suggestions would be highly appreciated!

You can refer "uhd_burst_detector.py" in "gnuradio/examples/tags" as a
starting point.

Hello all,
Many, many, thanks for the suggestions! I just tried the example by Lou -
very good way to update the filename - didn't realize the variable statement
was that powerful.
I will also test the tagged file sink and - indeed - I have started reading
the HOWTOs.
Again, many thanks for the

The file sink is either being directed to "filename" or "/dev/null". You

Hi Staffan,
I think that you'll find the things you describe can be best noted more
or less algorithmically (which you have already done!); and thus, I'd
think it's easier to actually write that specific sink you need than to
do what you want to do in GRC (I must admit I can't think of a way of
