DRA818 module comes in two versions: DRA818V, that covers freq. from 134 to 174 MHz and DRA818U that covers freq. from 400 to 470 MHz. I have the VHF version.
At the present I have programmed it to have:
1. simplex channels with 12.5 kHz step
2. repeater channels with 12.5 kHz step (subtones included)
3. Echolink repeaters (covering local Echolinks) (subtones included)
4. free freq. set with steps 12.5 kHz, 100 kHz and 1 MHz
5. set squelch level, volume and microphone level
