I am using a Kenwood 480SAT with RRC SW 2.90 with Samsung S5 and RRC-NANO 1.5.1.
Connected via bluetooth in the car the nano makes a really cool accessory for drive time HF operation but the PTT is a problem. I don't know how the TS480 manages the configuration but it would be really nice to have VOX with nano. I tried setting up VOX via RRC-control but the configuration did not stick when I then connected via nano.
