+  * On arrival (25/3/24) the Dual-Hat board had the wrong firmware (''MMDVM_HS_HAT'') and would not operate correctly as a duplex/two-timeslot hotspot.
+  * Pi-Star has capability to upgrade attached MMDVM firmware, but attempts to load ''MMDVM_HS_Dual_Hat'' repeatedly failed
+  * The firmware upload function was locked but unlocking was a simple matter of solder-bridging the pads of "JP1" on the MMDVM board.
+  * Pi-Star Firmware upgraded successfully to ''MMDVM_HS_Dual_Hat v1.6'' and duplex/two timeslot functionality was successful
