// UZ7HO Soundmodem Port by John Wiseman G8BPQ

// UZ7HO Soundmodem Port

// Not Working 4psk100 FEC 

// Thoughts on Waterfall Display.

// Original used a 2048 sample FFT giving 5.859375 Hz bins. We plotted 1024 points, giving a 0 to 6000 specrum

// If we want say 300 to 3300 we need about half the bin size so twice the fft size. But should we also fit required range to window size?

// Unless we resize the most displayed bit of the screen in around 900 pixels. So each bin should be 3300 / 900 = 3.66667 Hz or a FFT size of around 3273
