the text that is saved is only the text to the left of the Enter symbol. If you select this symbol and
press the LEFT button when you are not at the furthest right position of the message, then
everything right of your position is deleted.
Enter Right (finished):
The behaviour of this symbol is the same as Enter, except that it
preserves all the text, including the text to the right of the cursor. It simply saves the whole line.
2.7 Menu configuration settings
The following sections explain each configuration menu item in detail.
Preset 0
010,000,000
10 presets are available, labelled 0 to 9. Preset 0 has a factory default value of 10,000,000 and is
loaded into the VFO at power up. The other presets are defaulted to 0.
Clk 1
009,002,000
The Clk 1 parameter allows you to set up the Si5351A Synth on a frequency of your choice, on its
Clk1 output. Clk1 may be set anywhere in the permissible frequency range of the Si5351A. Here it is
shown set to 9.002MHz for example. If Clk 1 is set to 0 (the default value), then the Clk 1 output is
switched off.
The Clk 1 output could be useful for example as the BFO in a receiver, with the Clk 0 output as the
VFO. Note however that some degree of crosstalk does occur between the outputs, this is an
unavoidable limitation and may be an issue in some applications where high performance is required.
IF Offset
+009,000,000
IF Offset allows you to use this signal generator as a VFO in a superhet radio, and set this value to
your Intermediate Frequency (IF) offset. The actual output frequency is the displayed frequency plus
the IF Offset. The default value is 0. In this example it is set to 9.0MHz. Both positive and negative
offsets can be used.
