frequency calibration

WX6P

Hi, is there a write up on how to calibrate frequency on a 6400 without GPS using WWV?

Radio Tab:

Calibrate the local oscillator by performing the following steps:

1. Select a signal of known frequency, with strength greater than S6. In the US, WWV is a good choice.

2. Enter the known frequency in the Calibration Frequency field

3. Click Start. The radio will tune to the signal and compare its tuned frequency to the declared frequency. The difference will appear in the Offset field. You can also enter a value directly into the Offset field.

I won't repeat it all - you can follow it in the manual.
