I always change the lines:
#define LOWEST_FREQ (6990000UL) // absolute minimum frequency (Hz) |
?#
define HIGHEST_FREQ (
7500000UL)
// absolute maximum frequency (Hz)
to a LOWEST_FREQ of 7000 and a HIGHEST_FREQ of 7300 before I upload it to the Raduino. This limits how far outside the band it runs up/down. Other values can be used if desired.
