I updated my MD-390 with the modified firmware. This fw. gives among others, these new functions:
- Promiscuous mode. Listen to all voice groups on one timeslot. Even if you havent programmed the VG in a channel.
- See last heard on the display on all VGs on the time slot you have assigned to the channel regardless if you have enabled that VG
- VU meter for TX audio
- Updated contact list database
- Display dimming timer and intensity adjustable
- Lower beep audio on transmit not allowed etc
- List of last heard
- Channel info on display: tx freq, rx freq, timeslot, TG, sender ID, repeater ID etc
