Simplified setup, added automatic DMR caller identification and D-STAR position report decoding. — summary by updatemystuff.com

sharkrf.comRelease notes & downloadShow release notes Hide release notes
Added support for decoding timestamp fields in D-STAR DPRS messages, this allows receiving DPRS position reports from ICOM IC7100 transceivers Added “Force generate talker alias to modem” option to the DMR settings.
If it’s enabled, the openSPOT2 generates a talker alias to the stream sent to the modem based on the information available in the DMR ID database.
This can be used on networks which do not generate talker alias automatically, but you want to see the incoming call’s callsign and name on the transceiver’s display.
Added TGIF talkgroup handling to the ID database with the new “Preferred talkgroup list” option at the DMR settings section.
