Replace the VCO Adjustment Cover. Click Start Centre Frequency and using a frequency counter (via
an attenuator!), check that the transmitter carrier is on the correct frequency (within 150Hz). If not,
adjust the frequency using the Centre Frequency slider (left mouse button click and hold). Fine
adjustment can be better achieved by using the left and right arrow cursor keys on the PC keyboard,
once the slider has been selected with a left mouse button click:

DATA MODULATION ADJUSTMENT

Select and repeat this adjustment for Data ‘1’ Frequency and Data ‘0’ Frequency modes, which should
be set to:

Slider

25 KHz Bandwidth

12.5 KHz Bandwidth

Data 1 Frequency

Carrier minus 4.5 KHz

Carrier minus 2.25 KHz

Data 0 Frequency

Carrier plus 4.5 KHz

Carrier plus 2.25 KHz

Data Shape (Deviation)

4.5KHz

2.25KHz

Data ‘1’ frequency

MUST

be set before data ‘0’ frequency.

Once the frequencies have been set, the Data Shape Adjustment must be set. The easiest way to do
this is to connect a modulation meter to the output (via an attenuator!) and adjust the Data Shape
slider for the correct deviation. The required data is generated by the software. Once deviation is set,
click on Stop Data Shape Adjustment and close the Frequency Adjustment window:
