DMR use with simplex hotspot
Most Ham operators nowadays do have their own personal hotspot. Some of
those hotspots do support ‘full duplex’, others only support ‘simplex’ operation. In
order to successfully use a simplex hotspot with your Radiod d ity DB25-D or
Radiod d ity GD-88, the digital channel definition needs to be different than for
duplex repeaters or duplex hotspots. Whilst duplex-systems use DMR Tier 2,
simplex systems do use DMR Tier 1 or Tier 2 but requiring to use just one fixed
Time Slot (often TS 2).
In order to instruct the radio to use DMR Tier 1 (which is only possible when TX
and RX frequency are both the same), select the option ‘On’ for ‘RX T S ’ and ‘TX T S ’
within the channel definition.
All other required parameters are identical to those of a duplex channel.
Notes: The option to set ‘ RX TS ‘ and ‘ TX TS ‘ to ‘On‘ is only available if RX and TX
frequency are both the same and 'CH Mode' is set to 'Digital'
13.13 RX CC (Color Code)
Users can assign a color code for a RX channel. The channel Color Code can be
same or different, but a repeater can have only one Color Code.
A single Color Code is used to identify a single system. Different Color Codes are
used to identify multiple systems sharing the same frequency. This feature can be
switched between channels using the same operating frequency but with different
Color Codes.
Normally the Color Code RX and TX must be set to the very same value.
