What's in this update

Changes from Release E3

Fixed the problem where the call-ending frame may not be sent when transmitting the D-PRS DV-A or NMEA DV-G position data in the DV mode using Release E1 or Release E2 firm​ware.

Release E3 fixes the following problems.

The call-ending frame was not sent after releasing PTT. This caused a delay in sounding the standby beep from the receiving transceiver.

The repeater does not stop transmitting the downlink soon after the transceiver finishes transmitting the uplink.
