As I mentioned in the previous mail message my IR transmitter
on the handy board oscillates @57kHz.
I ordered the exact parts# form digikey as specified in the HB
documentation and also did the math. The result should be a freg
between 39 -40kHz.
Resistor R4 is 3.83K!
Would the 10K resistor (R4) have something to do with it?
