6.5 PROGRAMMER MENUS
The DTX Programmer has five menus or pages, selectable via tabs at the top of each page,
which are always visible. These pages are:
1. Frequency-Used to program the channel frequencies of the radio.
2. Settings-Used to set programmable features/functions of the radio.
3. Alignment-Used to align and set the internal digital potentiometers in the radio. Information
on the use of this page is found in the Maintenance section of the manual.
4. Summary-Used to summarize on one page the model, settings, and alignment information.
5. Restore Data-Used to program the unit with a set of previously saved frequency and setting
values.
The programmer also has radio buttons on the top right of each page. These are:
1. Receiving-This button is the software equivalent to the hardware PTT input. Clicking on this
button forces the radio into transmit mode where the button will change to Transmitting.
Clicking it again will put the radio back into receive.
2. Monitor-This button is the software equivalent to the hardware RX MON input. Clicking on
this button will override any squelch operation.
3. Clone Radio-This button is used to update the radio with the changes that have been made
via the programmer as shown on the programming screens with the exception of the
deviation and balance settings. Since the deviation and balance settings are unique to each
radio, even though the actual deviation may be the same, this button allows the personality of
one radio to be shown on the programming screens and then loaded into another radio. Also,
if the programmer is disconnected and then reconnected, this button will still function. If the
deviation and balance settings have not been changed which is normal, this button is
performs the same as the update radio button below.
4. Update Radio-This button is used to update the radio with all of the changes that have been
made via the programmer. Although the radio accepts changes as they are made via the
programmer, the changes are volatile i.e. they are lost when the radio is powered off. Clicking
on this button makes the changes non-volatile so that they are saved and stored permanently
unless changed via the programmer.
5. Read Radio-Forces the programmer to do a read of the radio to update the programmer
screens with the current state of the radio. This allows a radio to be connected to the
programmer and powered up without closing and then reopening the programmer.
6.5.1 FREQUENCY SELECTION
The Frequency page has fields for the transmit and receive frequencies of each channel.
Channel information can be entered by clicking on the appropriate box and entering the desired
frequency. The frequency chosen must be within the operating range of the radio and on a
frequency for which the synthesizer is capable of channeling i.e. for VHF, divisible by 2.5 kHz and
for UHF, divisible by 5 or 6.25 kHz. When the RNET compatibility mode is chosen via the
settings menu, only channel one and two are available for programming.
6.5.2 SETTINGS
The Settings page allows for programming various parameters of the radio. These are detailed
below:
Audio Input- Allows a choice between the two audio inputs for transmit, the Aux In input and the
Microphone input. As a rule, the microphone input has higher gain, but conversely, cannot accept
as high an input level. If the Microphone input is selected, the Microphone Gain box to its right will
allow a choice of two gain settings; there is no microphone gain setting available on the alignment
page. Note that even if signals are applied to both inputs, only the one selected will be
transmitted. Factory default is AUX IN.
