I've written an application for my client. The application works great (monitoring multiple channels for radio traffic and recording the demod FM stream). The client would like to see a couple of lights that show activity on the channel rather than a FFT GUI plot, which I like. Does anyone know of a "indicator" (on off light) that I can put on a GUI? Alternatively, maybe a VU meter widget?
The Indicator would show when a squelch is active or a threshold has been crossed.
Thanks for any ideas.
