No guess, taken from an usb snoop when presto was tuning to 482MHz.

Presto says that it is 482MHz. The documentation of the transmitter
station also says that it transmits this signal at 482MHz.
For testing purposes, I changed:
else if (div < 217)
rd[15].value = 0xd3;
into
else if (div < 218)
rd[15].value = 0xd3;
Instead of checking for equality to 217. This also fixes my tuning problem. Could it be an off-by-one error?
Is the 0xd3 value taken from the datasheet of this tuner?

Jan
