Only the active display, the display with the arrow indicator or the display selected by Menu 34 TDR-AB, will receive signals while receiving FM broadcasts.
When Menu 3 SAVE (power saver) is enabled, MENU 6 ABR (backlight timeout) is set to 9 or 10, and FM broadcast reception is active, several seconds after receiving a VHF or UHF signal the radio will make open squelch noise bursts over the FM broadcast audio and not properly revert back to the FM broadcast band receiver.ĭual Receive (TDR) does not work while the FM broadcast receiver is active. UV-5R BFS311 130903N Factory Frequencies Ch Freq Tone
The exact frequencies and number of channels may vary with different models and firmware versions. Several people have reported newly purchased units with the following frequencies preprogrammed from the factory. To enter 451.0125 the step can be set to either 2.5K, 6.25K or 12.5K and you must press or. To enter 451.00625 the step must be set to 6.25K and you must press or. To enter 451.0025 the step must be set to 2.5K and you must press or. You must have Menu 1 STEP set to the correct step size. 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. The kHz part of the frequency (the digits to the right of the decimal point) must be divisible by the step size (Menu 1 STEP). When entering frequencies via the keypad in VFO (Frequency) 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. In dual watch mode (Menu 7 TDR ON) the receiver on time is doubled to approximately 0.4 second due to checking two channels instead of one.īattery saver is activated after ~9 seconds of no receive and no keypad activity and is not active while scanning. When Menu 3 SAVE is enabled, the receiver is periodically turned off to reduce power consumption. Unit was purchased in 11/2013 and may have been manufactured the same month. 3 UV-5R Stock Dual Band Helical Antennaīaofeng UV-5R Notes (BFS311 Firmware) Test Unit. 1 Baofeng UV-5R Notes (BFS311 Firmware). _Then_ hit the '*' key to go into 'reverse' mode (sway transmit and receive frequencies), and then use MEM-CH to store the transmit frequency. The radio would report 'receiving memory' then 'transmitting memory', but would not transmit 'receive - offset' as one would expect.įinally I found a website that described the 'correct' procedure to follow: enter the receive frequency, then the offset, then use MEM-CH to store the receive frequency. I spent quite a while following the instructions and programming the receive frequency and the offset, then using the 'MEM-CH' menu option _twice_ (as per the instructions). Unfortunately the documentation and user interface on these radios is not very clear, and if you don't enter setting in exactly the right way (not necessarily documented!), the radio will simply take your input and discard it, without presenting any sort of error message.ġ) As was said above, make sure you are in VFO mode in order to program the memory if you are in memory mode and program a value it will just vanish.Ģ) If you are trying to program the memory location for repeater use, you have to _separately_ program the receive and transmit frequencies.
