Ritron DTX-165-0 Maintenance And Operating Manual page 22

Audio PA Gain- Sets the audio level of the AUDIO OUT output. Note that the AUDIO OUT level is
also affected by the Aux Out(RX) Gain setting. Therefore, the Aux Out(RX) Gain should be set
before setting the Audio PA Gain, even if the AUX OUT output is not being used. If the AUX OUT
output is not being used, the Audio PA Gain should be set to 0.
Deviation and Balance- Set such that the maximum deviation will fall within the regulatory
requirements and the transmit audio response has the correct characteristics. Deviation and
Balance do not need to be adjusted after a change in programmed frequency. New values are
calculated by the radio when a frequency is entered in the frequency menu. The values are
shown in the box at the bottom of the page on a per-channel basis. Note that even though the
values may differ by channel, unless the values in the boxes have been edited, the deviation and
balance of the radio will be the same on all channels, just the values to achieve equal balance
and deviation may differ. One can actually modify the calculated deviation and balance values per
channel by entering values in the boxes, but this requires the services of a very qualified
technician and the proper test equipment. The radio has been properly aligned at the factory and
should not need to be adjusted. Details on how to perform these adjustments are found in the
Alignment section.
TX Low Power and TX High Power- Sets the global power level for the transmitter in watts for the
two positions of the CSN input. A logic high on the CSN input would cause the radio to use the
TX High Power setting while a logic low on the CSN would cause the radio to use the TX Low
Power setting. Note that the names Low and High Power are purely arbitrary and that the Low
Power value can actually be set to be higher than the High Power value if desired. If it is desired
that the power levels be set different values for different channels, the desired power levels can
be inserted into the box at the bottom of the page. Note, however, if a change is made in the TX
Low Power and/or TX High Power values in the slide bar area, it will affect all channels equally.
Instructions for using the alignment page can be found in section 13 of this manual.
6.5.4 SUMMARY
The summary page summarizes the information shown on the other three pages and, in addition,
includes the model and serial number of the unit.
6.5.5 RESTORE EEPROM
This selection is used to load a previously saved radio configuration file to the radio connected to
the programmer. This is of benefit when a number of radios are to set to the same frequencies
and with the same switch settings. There are three options for this page, but none will copy the
deviation and balance settings since these are unique to each radio, even if the actual deviation
of a set of radios is identical. The top selection allows all settable parameters, including power
levels and squelch settings to be read. The second selection does not read in the power levels
and squelch in case these have already been set in the recipient radio. The last selection is for
someone who has a configuration file from a series DTX-X54 and want to load it into the series
DTX-X60. Older radio parameters are converted and presented such that the audio levels should
be the same. Note that the RF power levels and squelch levels cannot be converted and must be
set on the new radio by hand.
6.5.6 SAVING A CONFIGURATION
Upon exiting the programmer via the exit button, the user will be presented with a box which
allows the saving of the current configuration. This is useful if a number of other radios are to be
programmed with the same frequencies and settings. If one does not wish to save the current
configuration, the cancel icon should be selected. Also, if changes to the radio have been made
via the programmer and the radio has not been updated, the user will be prompted to update the
radio.
