Actually, playing around with it some more (the version in the stable
repository), it appears to be picking something up.  "radio -s" produces
the following:

$ radio -s
baseline at 1.00
Station  0:  88.10 MHz - 4.00
Station  1:  88.90 MHz - 3.00
Station  2:  89.70 MHz - 2.00
Station  3:  91.50 MHz - 2.00
Station  4:  92.35 MHz - 3.00
Station  5:  93.10 MHz - 3.00
Station  6:  95.10 MHz - 3.00
Station  7:  95.90 MHz - 2.00
Station  8:  97.80 MHz - 4.00
Station  9:  99.10 MHz - 2.00
Station 10: 100.45 MHz - 2.00
Station 11: 101.90 MHz - 2.00
Station 12: 102.70 MHz - 2.00
Station 13: 104.25 MHz - 4.00
Station 14: 105.75 MHz - 3.00
Station 15: 106.50 MHz - 5.00
tuned 88.10 MHz

I assume that the last number is a measure of signal strength?

The problem is that no sound is produced.  FYI, gnomeradio gives a
'Could not open "/dev/mixer"!' error.  There seem to be some bugs
reported regarding this problem.
