rtlsdr-waterfall's Issues

GAIN adjustment doesn't work.

I get:

File "waterfall.py", line 102, in gain_change
i = self.sdr.GAIN_VALUES.index(real_g)
AttributeError: 'RtlSdr' object has no attribute 'GAIN_VALUES'

when I hit a bracket to adjust the gain.
Searching for the error message:
http://eartoearoak.com/software/rtlsdr-scanner
seems to indicate that the python-rtlsdr API changed, and that a small change in the code is required.

some frequency ranges seem to cause invalid readlengths to be fed to the rtlsdr bindings

IOError: Error code -8 when reading 128 bytes

Running "python waterfall.py 50e6 200e6" with a R280T based dongle gives the following traceback: http://itdaniher.com/p?MXPb

The traceback goes away and the code seems to be working if I change the code as per http://itdaniher.com/p?HFty, setting the read side to a constant 512 bytes.

I don't have the time to put together a "real" patch right now, but just wanted to let you know. Thanks for your project!
