I'm pretty sure there are 3 selectable power levels accessible through the screen, and I think they would be 0.5,5,10. Additionally, I believe that the PC CPS allows power level to be selected as well as CTCSS/DCS setup, wide/narrow band, scan inclusion, etc. My 'program list' is pretty consistent throughout my Retevis collection (NR30,NR30s,NR630s,RB89,RB26/RB626,NR10); I have a GMRS setup (30 channels), a dual-band setup (approx 60 channels) and an FRS setup (16 channels). When using a PC to program multiple radios it goes pretty quick; I save the latest channel list to 'documents' prior to writing to the radio. NEWBIE HERE!!
