Hi,
I am trying to get some audio signal (radio signals in the range of 89-107M)
from am_rcv.py, but getting following dump. Am i doing it correctly ?
Otherwise what could be the other possible reason for this? Help me to sort
out this problem.  

gnuradio-3.0.4/gnuradio-examples/python/usrp$ ./am_rcv.py 91M
Traceback (most recent call last):
  File "./am_rcv.py", line 113, in <module>
    app = stdgui.stdapp (am_rx_graph, "AM RX")
  File "/usr/local/lib/python2.5/site-packages/gnuradio/wxgui/stdgui.py",
line 36, in __init__
    wx.App.__init__ (self, redirect=False)
  File "/usr/lib/python2.5/site-packages/wx-2.6-gtk2-unicode/wx/_core.py",
line 7700, in __init__
    self._BootstrapApp()
  File "/usr/lib/python2.5/site-packages/wx-2.6-gtk2-unicode/wx/_core.py",
line 7352, in _BootstrapApp
    return _core_.PyApp__BootstrapApp(*args, **kwargs)
  File "/usr/local/lib/python2.5/site-packages/gnuradio/wxgui/stdgui.py",
line 39, in OnInit
    frame = stdframe (self.flow_graph_maker, self.title, self._nstatus)
  File "/usr/local/lib/python2.5/site-packages/gnuradio/wxgui/stdgui.py",
line 60, in __init__
    self.panel = stdpanel (self, self, flow_graph_maker)
  File "/usr/local/lib/python2.5/site-packages/gnuradio/wxgui/stdgui.py",
line 81, in __init__
    self.fg = flow_graph_maker (frame, self, vbox, sys.argv)
  File "./am_rcv.py", line 18, in __init__
    station = parseargs(argv[1:])
  File "./am_rcv.py", line 105, in parseargs
    freq1 = float (args[0]) * 1e3
ValueError: invalid literal for float(): 91M

Thanks,
Sachin
