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. BR/JC

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!
