6.2.1.1 VHF Receiver
6.2.1.2 VHF Frequency Setting
The international channel convention of 8.33kHz provides 16 channels per 100kHz of bandwidth
and as a consequence not all frequencies are available. For example, 134.810 is valid but 134.815
is not.
Frequency reading
Note that in the screen (over the page) the frequency is displayed as 134.808MHz even though
the channel selected is 134.810. This is because the channels are a simplified and rounded (down
or up) representation of the frequency used.
A table showing the first 16 channels versus their frequency is shown below. The user does not
need to know any of this detail.
Channel Frequency Channel Frequency Channel Frequency Channel Frequency
118.000 118.0000 118.025 118.0250 118.050 118.0500 118.075 118.0750

118.015 118.0166 118.040 118.0416 118.065 118.0666 118.090 118.0916
Note that the 25kHz spacing channels (italics) are an exact frequency but that the 8.33kHz
channels are not.
This pattern is repeated every 100kHz for all 3,040 channels.
