12.10.1 Analog APRS
For Analog APRS data, check which frequency and further parameters are to be
used for your region. Within the CPS, those settings required for analog APRS are
specified within the following block:
Notes: Analog APRS may be assigned to a channel as ‘APRS(A)’. However, analog APRS
only works when assigned to an analog channel.
12.10.2 Digital APRS
For Digital APRS a DMR network is required and the APRS-message is sent to a
certain TalkGroup either as Private or as Group call, depending on the DMR
network and country/region. A total of 8 possible Digital APRS settings may be
defined. Within the channel definition one of those 8 digital APRS settings or the
analog APRS setting may be selected for APRS reporting of the specific channel.
12.10.3 Manual TX Interval[s]
When using analog APRS, an APRS packet (beacon) will be send out on the very
first use of the [PTT]-key. This also triggers the ‘Manual TX Interval timer’. As long
as the timer has not reached its specified value, new APRS packets will not be send
when [PTT] gets depressed. This APRS packet transmission is independent of the
specified ‘APRS Auto TX Intervals’.
Interval period: Maximum: 255
Minimum: 0
Increment: 1
Recommended: 30
