Re: [Discuss-gnuradio] burst detector files

I understand, it turns out I misread how the flow graph routed the vector 
source. I thought that the internal trigger was flowing in as a source rather 
than the RF threshold. Thanks for the help.

Eugene,

That's actually not a very weak signal. Convert it into dBm and see what it's 
power is.

When working with real signals over the air, you have to get used to working 
with small numbers.
