"-" and "+" are used to designate the direction that TX is shifted from RX
(lower in frequency and higher in frequency, respectively)
-600 would mean set Duplex = "-" and Offset = "0.600000"

When you use "Split" you enter the TX frequency directly into the Offset
column. In your 146.445 example below, the frequency that your radio needs
to transmit on is 1 MHz above the RX frequency.
In this case you would set Duplex = "Split" and Offset = "147.445"
But once you press the [Go] button, Duplex will change to "+" and Offset
will change to "1.000000" (another way to say the same thing)

When you enter a ham repeater frequency such as 146.640000, CHIRP will
recognize this as a 2 meter repeater frequency and automatically set Duplex
and Offset.

May be something to do with Wideband mode verses Narrowband mode. This is
the Mode column in CHIRP which can be set to FM (wide) or NFM (narrow).

left out until you understand how CTCSS works. It is the CTCSS tone for
receiving and if you set it wrong you will not hear anything.

You do not have to program this tone.

It you program this into your radio and the tone is not being transmitted,
you will not hear anything. Do not program receive CTCSS tones unless you
understand how they work and know why you really need it.

Click in the cell. You will then see it change and you will then know it is
ready for input.
