Specifications

JST Transceivers
TRX-manager supports JRC JST transceivers and the NRD-545 receiver with some limitations
on program functionality.
Settings
Choose NRD-535 NRD-545, JST-145 or JST-245 from the Setup dialog box. The JST
Protocol is equivalent to the JST-145/245 protocol, however using this setting TRX-manager
will not read data from the radio. In this mode, communications speed is fixed at 4800 bps.
If necessary, press the CATbutton ( CAT control ) in order to activate remote control.
This mode takes over control of the radio after lighting the "REMOTE" light on the radio
faceplate (there is no manual control from the radio controls while in this mode, not even the
tuning dial !). CAT ON is absolutely required for Scanning otherwise erratic behaviors
may occur. However, tuning a spot (using DXor Web-Cluster) tuning a SW Station or
controlling the transceiver (except utilizing the memory channels) does not require activating
CAT mode. For long scannings, it is preferable to choose CAT ON.
If CAT is OFF, all changes to frequencies, modes and filters are displayed by the program.
When communications is working properly, any changes made on the radio will be reflected in
TRX-manager, with the exception of splits which are not supported. If the current
Frequency end Mode do not appear at startup, please turn a little the tuning dial.
The Split mode is not supported via computer.
Memory channels (CAT ON only)
If CAT is ON, you can control the memories (Write only). With TRX-manager it is possible to
store data into memories 1 to 99 (only). For the JST-145/245, the program memorizes the
split frequencies and the repeater shifts can be entered into the memories.
TRX-Manager can NOT read the memory channels content.
Filters
The JST receivers and transceivers support 3 selections per mode. The program allows you to
choose any filter, however, the display may differ from the actual selection. See also Mode
and filters.
