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.
TX Pre-emphasis- Allows for the signal path from AUX IN and the MIC IN input to be either pre-
emphasized or flat. Most applications where the AUX IN input is used work best with a flat response.
Factory default is flat response.
