Note: Although in the Programmer you can set offset and other
transmit related data for frequencies outside the transmission abilities
of the radio, the software will not enable transmission on these
frequencies. Transmission will be possible only if the radio is properly
modified.
Offset Frequency : The mathematical difference between the transmit and receive
frequencies of a repeater. Icom radios handle all repeater frequencies with an Offset
Frequency (the difference between the transmit and receive frequency) and an Offset
Direction (+ or -).
Icom radios use an Offset Frequency of 0 to 9.99900 MHz with a Plus or
Minus Offset Direction for the 144/430 Bands and 0 to 99.999900 MHz for the
1.2 Ghz band.
Offset Direction : If necessary, manually set the Offset Direction to one of the options
available for this radio. The Programmer will make a selection automatically based on
the receive frequency; however, the details for a particular repeater may differ from the
standard band plan making it necessary for you to make a selection other than the
default. Select from
Simplex - transmit and receive frequencies are the same;
-DUP - the offset frequency is subtracted from the receive frequency (i.e., the
transmit frequency is less than the receive frequency as in RX 145.520 TX
143.425) The transmit frequency shifts down from the receive frequency.
+DUP - the offset frequency is added to the receive frequency (i.e., the
transmit frequency is greater than the receive frequency as in RX 144.250 TX
147.335) The transmit frequency shifts up from the receive frequency.
For some D-Star activities, you need an Offset Direction of +Dup or -
Dup with an Offset Frequency of 0.00Khz so you are actually
operating Simplex. You have complete control of these fields for the
channel. Simply make changes as needed to set up for the device
you're using. Since with D-Star you often set up multiple channels,
you can make this change later for all the channels with column copy
and paste rather than having to change each channel individually.
The D-Star calculator will set up this configuration for you. See
details for that option in the
D-Star Calculator section of this help.
Operating Mode : Select the appropriate operating mode for the channel.
