Re: [Discuss-gnuradio] GRC, Recording chunks of spectrum triggered on input signal level

[Staffan Bruce]

Hello,

After some weekend experimenting I believe I have most (most...) of it 
working. Sinking to a USB stick is not working so well by the way...
One thing that is still a challenge is how to set the filename. You provided 
a very good way of timestamping, but when I try this, it only evaluates 
once - when I start the script. Is there any way to force re-evaluation of a 
variable?
In addition, it would be great to have some kind of a counter (variable, x = 
x + 1) that can be updated depending on a state change - for example when a 
trigger event occurrs. I tried some different versions, but mainly ended up 
in circular references...

Any suggestions would be highly appreciated!

Regards,
 Staffan
