What's in this update
Changes from Version 1.20
Fixed the problem where the scan might not stop, even when the transceiver receives a signal.
With the previous firmware, there was a delay in sounding the standby beep when the transceiver communicated with other manufacturers' DV equipment*.
With the latest firmware, the transceiver sounds the standby beep with no delay, even when the transceiver communicates with other manufacturers' DV equipment.
- It does not occur when directly communicating with transceivers and/or application software made by Icom or Kenwood.
