Frequency calibration
(approximate)
A very accurate frequency counter is required to cali-
brate the frequency of the receiver. However, a rough
check may be performed by receiving radio station
WWV, WWVH, or other standard frequency signals.
CAUTION:
The IC-R9500 has been thoroughly ad-
justed and tested at the factory before being
shipped. You should not have to re-calibrate it.
