</span><span style='font-size:10.0pt;mso-bidi-font-size:12.0pt;font-family:

<u>Explanation: <br>
</u><br>
Set the minimum value to -160 (corresponds to [median] S0 on the S-meter) <br>
Set the maximum value to -50 (corresponds to [median] > S9 + 40 dB) <br>
Set the number label at every 10th increment <br>
Set the Y-axis tick mark at every 2nd increment <br>
<br>

</span><span style='font-size:10.0pt;mso-bidi-font-size:12.0pt;font-family:

<u>Explanation: <br>
</u><br>
Set the minimum value to 0. This is, in fact, too low. A minimum value of 20
would do. <br>
Set the maximum value to 100. For big BC stations, this can be too low a max
value... <br>
Set the number label at every 10th increment <br>
Set the Y-axis tick mark at every 2nd increment <br>

<u>Explanation: <br>
</u><br>
Set the minimum value to 0. This is, in fact, too low. A minimum value of 20
would do. <br>
Set the maximum value to 100. Now, this can be too high a value. However, now
at least, the SNR and SNRxx scales are the same. <br>
Set the number label at every 10th increment <br>
Set the Y-axis tick mark at every 2nd increment <br>
