Do not increase the
Tx Level
past the position where the power out stops increasing. In some
situations, you may not be able to set for 5 Watts output power.
Frequency Calibration
Frequency calibration is a relatively simple process. You will need a very stable signal of
known frequency such as WWV or a signal from a calibrated signal generator.
We will use WWV for this procedure.
1.
Select PSK-U
2.
Tune to WWV at 10MHz or
15MHz, Figure 77
