The BF-888S is a Single Band, UHF, 400-470MHz, low power radio. The specs say <=5W, and that's exactly what 2 watts is. I have two and on 446.0MHz, one shows 1.9W the other 2.0W. The factory software only supports 5kHz steps, however CHIRP allows 2.5kHz steps. The receiver sensitivity is very good, but the selectivity is average at best. In a heavily RF congested area, the lack of filtering would become very apparent. It does support CTCSS/DCS as well as Channel Scan which is a good thing. There is no keypad, so a programming cable is a must. No software is included with the radio, but it is readily available and can be downloaded from Miklor.com. The OEM software is easy to follow but has its shortcomings. The good news is that CHIRP also supports it, so TX/RX offsets are easily programmed.
