Thanks Marcus. I
want to build a marine VHF scanner with an RTL-SDR. So I start at the
base
marine frequency, evaluate the channel power, and if less than a threshold, go
to the
next channel, until I see a power > threshold which indicates
activity and I stop scanning
and switch to demodulation. My base schematic
is attached just the demod so far. The idea
was to time step the Range
Variable center_freq.

Hi Jeremy,
that sounds very much like your use case calls for a stream of samples rather
than a variable being updated. Would that be possible?
It's a bit hard to help you without any context, so if you could describe
what you're doing, or share a flow graph, or anything, that might
help!
Best regards,
Marcus

Is there a simple way to time step a range variable? Say
start at “start” value and step for x_msecs, till ”stop” value reached.
Tnx.
