Yes there is separate setting, so I have to separate them into software.

TMODES = ["", "TSQL", "DTCS", "VSC"]

>"VSC" isn't a valid tone mode. You'll get an error when you try to download a channel if you do memory.tmode = "VSC".

It's True. I copied this value from Icom's software.

TUNING_STEPS = [0.01, 0.1, 1.0, 5.0, 6.25, 8.33, 10.0, 12.5, 15.0, 20.0, 25.0, 30.0, 50.0, 100.0]

The IC-R20 scanner is really powerful, it can work on all frequencies between 150KHz and 3GHz. Steps Tuning settings actually exist in this unit and can be used on all frequencies.

mem.tuning_step = TUNING_STEPS[_mem.ts & 0x0F]

In fact _mem.ts contains the two ts settings (FM and SSB). This line is just for test purpose, to extract only FM TS.

Thanks.
