Hi,

I just tried running the example on a RFX2400 and it seems to work for me.

I think the error is caused when the usrp2object.gain_range() command
returns a step size of 0.00000 (like on the BasicRX).

As a quick fix you could try replacing:

        myform['gain'] = \
            form.quantized_slider_field(parent=self.panel, sizer=hbox,
label="Gain",
                                        weight=3, range=self.u.gain_range(),
                                        callback=self.set_gain)

with:

        myform['gain'] = \
            form.quantized_slider_field(parent=self.panel, sizer=hbox,
label="Gain",
                                        weight=3, range=*(0.0,70.0,0.03125)*
,
                                        callback=self.set_gain)

I couldn't find a reference to the Flex2400 DB ID after a quick look at the
USRP2 code which I think means the code will treat the daughterboard as if
it was a BasicRX.

http://www.ruby-forum.com/topic/177212 suggests you can update the EEPROM to
convert the board to an RFX2400.
