you must enter the next higher digit or use the up/down arrow keys to change the rest of the digits. If the third decimal place is not 0 or 5 the radio will round down to the nearest step.You cannot enter a frequency with more than 3 decimal places such as 451.0025 or 451.00625 using only the number keys.The radio will only accept 0 or 5 in the third decimal place.When entering frequencies via the keypad in VFO mode the radio will only accept 6 digits three before the decimal point and three after the decimal point.Mic audio can possibly interfere with transmitted tones. Setting Menu 16 DTMFST to OFF disables the sidetone but doesn not mute the mic.Setting Menu 16 DTMFST to DT-ST or DT+ANI mutes the microphone preventing it from interfering with transmitted DTMF and 1750 Hz burst tones.The mic can pick up the sidetone from the speaker and overdrive or distort the transmitted tones. Pressing keypad keys while transmitting does not mute the mic. If Menu 16 DTMFST is set to ANI-ST, the internal microphone is hot when DTMF or 1750 Hz burst tones are transmitted.Pressing the key sends '0' instead of 'D'. On firmware version BFS311, and possibly others, it is not possible to send a DTMF 'D' tone.The up/down arrow keys srcoll through the standard tone frequencies. CTCTSS transmit and receive tone frequencies can be set via the numeric keypad to any frequency from 60.0 to 259.9 Hz in 0.1 Hz increments.The UV-5R has a 26 MHz reference oscillator.

It is not known how much of this information is relevant to other firmware versions, models or clones from other manufacturers. From The RadioReference Wiki Most of the information on this page is also relevant to the UV-82 series and similar models that share the same microprocessor and RF chipset. I think it’s the most versatile, it has 2.5KHz steps, a small size, lots of accessories, FCC part 90 certified (so this can be used on Business Bands with an FCC license).

A few thoughts about each radio: The UV-5RA is still my favorite among the BaoFeng’s. BAOFENG UV-6 Handheld, Software and Antenna. Select the Settings / Other Settings tab, Firmware message 1 & 2 will show the actual firmware release. To find the actual firmware release, you need to run the latest CHIRP Daily Build. Baofeng has been updating the firmware and Not displaying the actual firmware number as described above.
