1. Remember one S point is 6dB doubling the power just adds 3dB to your output So with an increase from 2W to 4W you would only gain half an S unit lf you need more power e buy amore powerful transceiver e buy an external power amplifier e use a better antenna How to disassemble UV 3R Taken from message 342 hitp groups yahoo com group UV 3R message 342 by Clint Set down a piece of cloth on the workbench to capture screws and prevent the front panel and display from being scratched Remove belt clip Remove antenna Remove battery cover and battery Remove screw on the knob and pull off knob from the rotary encoder Remove orange silicone washer from around antenna connector UV 3R FAQ 4 version 2011 12 22 24 Remove the two screws in the battery compartment Note if they differ from each other and which one went where Lift out the rubber flap that covers the DC and Mic Speaker connection Lift the bottom of the radio out of the case very carefully It should go straight up until it clears the case and at that point the portion with the PTT alarm light buttons on the side should clear the case At this point slide out the radio chassis from the top hole that has the knob Note that the speaker connects with springs to the circuit board If they are bent noticeably remember to gently straighten them before reassembly Remove the nut from the rotary encoder Remove the four screws holding2. make sure no CTCSS DCS are set switch UV 3R off open up the UV 3R as described elsewhere solder about 10cm of wire in place of the antenna connector connect the earpiece connect the charger to UV 3R the radio will power up gently lay the bare board on the flat non conductive surface using a plastic needle gently press down components until the squelch opens Congratulations you have successfully identified the fault Now you need to fix it but that requires an expert technician and specialized tools My VHF UHF transmitter does not work RF is generated by the SDR chip inside UV 3R Then applied to a buffer stage and switched to a dedicated amplifying chain one per band Each amplifier is composed of a driver and a final Can you hear your transmission on a nearby receiver Is there a difference between high and low power Do you get the expected power on the other band If so the SDR chip is working and the fault is in the amplifier chain Could it be that there is a cold solder joint in the VHF UHF transmitter chain TBC What is the strong signal on 156 MHz The carrier on 156 000 MHz marine channel 0 is caused by the 6th harmonic of the internal 26 MHz oscillator This oscillator is used to run the main radio SDR chip so there is no cure Other spurious signals can be heard on UHF as well every few MHz Fortunately they all stay out of the HAM bands The FM radio does not work Hold the orange button on the side
3. The issue is that some of the aftermarket antennas are fairly bulky and can put a strain on the SMA connector If you plan on connecting your Baofeng UV 3R to an external antenna use one of the SMA to UHF or BNC jumper cables Some suggested brand models MFJ 1716S MFJ 1713S Diamond SRH815 Diamond SRH519 Maldol MH 511 Comet SMA503 Is the SRH805 antenna any good The short answer is NO The long answer is that an antenna needs to be long to perform in the case of UV 3R close to a quarter of wave at the operating frequency and this dual band antenna is just 4 5cm tall Beware of Fake SRH805 on eBay They are even worse but see the picture section for a mod UV 3R FAQ 4 version 2011 12 22 11 MEMORIES How do I manually program memories First get a list of the repeaters or simplex frequencies you wish to program into the UV 3R You will need Receive frequency for the repeater PL tone if needed Omit for the simplex frequencies of course Offset direction plus or minus Zero for simplex Shift value for transmit Usually 600 kHz for 2 meters 1 6 or 5 MHz for 70 cm oY Make sure you are in VFO mode for 2 meters Display should show NO channel number In case press hold U V key long enough to get there it will cycle through memory mode UHF VHF To set the receive frequency lift knob and rotate to get desired value For 1 MHz steps saves some time press and release function key then rot
4. writes to your HT If you already have something stored in your HT do a Device Read and save this before you do the Device Write It is convenient to have a number of different memory files for such things as locations you regularly visit weather channels NOAA in the USA LEO satellites or public service monitoring frequencies if allowed When you are done exit the program and disconnect the cable from the computer and the HT Please turn the radio off before inserting or removing the programming cable and save yourself the possibility of doing some harm to them Once basic programming is done with Baofeng software then the program called CHIRP works better The main difference is Chirp does not have basic setup or config options but is easier to use since it has copy paste and multiple setups with tabs as well as importing data from various sources Also Chirp allows just setting the offset not having to enter the separate transmit frequency Even copying a bank of 2 meter and 70 cm freqs from a Chirps supported scanner works for monitoring but that does not give the offsets for transmitting to repeaters Programming does not work Help Do a system reset Set up PL tone offset shift and power level Set frequency Press F S then VHF UHF to store in memory Rotate knob first if you don t like the default channel It is easier to use the programming cable and software in the event that you have more than a few channels to

13. 2 one UV 3R FAQ 4 version 2011 12 22 21 Can I use the programming cable to remote control UV 3R No Only memories can be read and written with the programming cable Can update the firmware with the programming cable No Only memories can be read and written with the programming cable Can I use Yaesu programming cables No as the pinout is different FM radio reception gets interrupted with VHF UHF signal This is a feature To avoid it set your radio to a fairly unused channel or set an unused CTCSS DCS code before going to FM However if you like to monitor traffic on your local repeater while listening to the FM radio just set it to your favorite repeater Does Chirp software work with the UV 3R Yes this works with the UV 3R CHIRP is a FREE cross platform cross radio programming tool It works on Windows and Linux and MacOSX with a little work It supports a growing list of radios across several manufacturers and allows transferring of memory contents between them Mike N4MEP tells how used CHIRP to read all my stored memories from a Wuoxun KG UV3DP saved them as a CSV file then read from the Baofeng UV 3R to create the correct image file and imported the saved CSV file Then finally wrote all the memories to the radio You can get more info and download it HERE UV 3R FAQ 4 version 2011 12 22 22 TIPS amp TRICKS During scanning if you turn the dial the direction of scanning
14. 36 174 MHz 400 470 MHz It is not possible to restrict transmission to HAM allocations only therefore this little radio might be illegal in your Country The RX TX range can be modified by UV 3R programming software to lesson the chance of illegal transmissions if required but may not satisfy legal requirements For more information on reprogramming band edges please see message number 2968 Also the TX frequency can be set to within Ham bands as a safety margin but this does not permanently restrict TX to those Ham frequencies alone What is wide narrow setting This setting controls RX bandwidth and FM deviation These have been measured to be TX max deviation wide 4 8kHz TX max deviation narrow 2 4kHz Apparent RX 6dB bandwidth wide 8kHz Apparent RX 6dB bandwidth narrow 4kHz Adjacent channel selectivity measured as ETS300 086 was 70dB wide and 58dB narrow What does RelayM do Apparently it delays the return to receive after transmitting This should cut the roger beep on repeaters that add it automatically See hitp groups yahoo com group UV 3R message 1921 for a possible answer Note some older models and manuals refer to ElayM instead of RelayM UV 3R FAQ 4 version 2011 12 22 20 What does the Save function do While the users manual says it reduces the transmitted power when the received signal is strong that seems to be a wrong copy and paste from a Yaesu manual Measu
