[Discuss-gnuradio] exploring samples by scanning

[Nathaniel Haggard]

To explore this large sample of spectrum it would be nice to scan
through it using the ssb demodulator.

To implement a scanner in python it seems like I need an incrementing
block, but I don't see one of those.

By scanning I mean:
1. if break squelch then play until squelched or keypress
2. increment frequency
3. goto 1
