mode2 reports noise values

Hi, all.

I have just build a homebrew receiver following the instructions and
schematics at lirc.org, and I've build and installed lirc from CVS.  My
electronics supplier couldn't provide the TSOP17 IR receiver, so I
substituted with the PNA4602M.

When I run mode2 without pressing any buttons, it rapidly prints
alternating pulses and spaces.  The values appear to be a random
distribution between 0 and about 2500.

When I run mode2 and press a button on my remote control, intermittent
values jump to nearly 40,000.  I graphed the values here:

My understanding is that mode2 should not print any values until a
button is pressed.  Will this make it impossible to record my remote
control commands?  Is there some way to tell lirc to disregard any
values below a certain threshold?  I have tried insmod'ing the kernel
module with sense=0 and sense=1, no effect on the result.

Thanks,

Russ
