If this is the first time either program is being utilized or if the operator has changed the PC’s serial
communications port being utilized, the first action taken by the user should be to establish the correct port
selection. This can be accomplished by doing a menu selection from the “Radio Comm Port” selection.
After this action, the user may select “Get All”. This will cause the software to interrogate the
interconnected STR-1800 series radios and then update the displayed fields. The Serial Number field
should reflect the five (5) digit serial number from the product label on the STR-1800. The model number
will indicate the specific model of the radio and the various version numbers will reflect the hardware and
software versions of the radio.
The main part of the screen indicates the current settings for the sixteen (16) preset channel selections of
the radio. This includes the channel frequency, bandwidth (i.e., wideband at 25 KHz or narrowband at 12.5
KHz) and output power level (i.e., “High” of 30 Watts, “Medium” (Undefined) or “Low” of 5 watts.).
3.4 Altering the Radio Configuration
3.5.1 Changing Individual Channel Settings
Once a radio has been read as described above, the channel configuration fields may be edited. The
frequency field may be changed by selecting appropriate field and holding it to show a menu list of all
available frequencies. Radios may be factory programmed for up to 512 frequencies. The frequencies of all
defined items will be displayed when the field is selected. The bandwidth and power selections are toggle
controls operate in a similar manner.
After establishing the changes to all channel settings, the user should select “Send All”. The system will
again interrogate the radio as to its current settings, modify the channel configurations according to the
edited fields, and then write the new configuration back to the radio.
By interrogating the radio again prior to modifying its settings, the software ensures the correct
configuration update even if a new radio has been connected to the PC since the last read radio action. As
such, a user may establish a channel configuration and then write the data to multiple radios simply by
connecting a new radio to the PC and invoking “Send All”. The fields on the screen will be updated each
time this action is taken.
3.5.2 Saving/Restoring Channel Parameters
This capability of the control program will be added on a future release.
3.5.3 Power Output Control
This capability of the control program will be added on a future release.
3.6 Radio Operation
Having established the proper channel configuration for the radio, the STR-1800 series radio is now ready
for target platform installation. The following operational considerations should be noted:
1) Radios which are powered up with an active push-to-talk condition will not operate until the push-
to-talk is removed and stay’s in a non-active condition for a period of 2 seconds.
