Q:  What is the difference between the various models of UV-82?
A:   There are currently only 3 models of the UV-82.
          UV82  -  This is the standard VHF / UHF model
          UV82X - This model covers VHF and 220 MHz Ham Band.
          UV82C - This is a VHF / UHF transceiver that is Part 90 type accepted for Commercial use in the US.
Note: Models such as UV82L, etc are rebranded versions of the above.

Q:  Are there any function differences between the various models?
A:   The UV82C has two functions that set it apart from the others.
-   The radio can be locked (via software) to prevent unauthorized tampering and changing of frequencies. Channel Selection, Scan, etc. will still function as before.
-   There is an option allowing the Dual PTT Button to function as a Single PTT.
Q:  What revisions were made to the UV-82 Firmware?
A:   A current list of known changes can be found here.       Firmware

Q:  How can I determine the firmware release of my UV-82?
A:   Power the radio OFF. 
      Press and Hold the 5 key. 
      Power the radio ON.

         The LCD will show 6 characters.    This is the Firmware release.

Q:  Can the UV-82 firmware be updated?
A:   No. The firmware cannot be updated.
      The microcontroller is an OTP (One Time Programmable)
      Once 'flash' programmed at the factory, it cannot be changed.
Q:  Is this radio FCC Part 90 certified?       (Commercial)
A:   The UV82C is certified for Part 90 commercial service in the US.
      The Model C requires software to prevent accidental field programming.
Q:  Is this radio approved for Ham Radio use?       (Ham Radio)
A:   Yes.  It may be used legally by any Licensed Ham in the U.S.
Note: This radio is not certified for FRS, GMRS or MURS operation in the US.
     Consult your country's regulations regarding proper use and licensing.
Q:  I can't key or hear my local repeater.
A:   Review the Tone Access section of this page.

Q:  I can't hear my signal through the repeater, but I hear the repeater tail.
A:  The key here is that you can hear the repeater squelch tail.
      You are too close to your receiver and over powering (de-sensing) it.
      When this happens, you are blocking everything from your monitor.
          1) Listen to your signal on simplex to verify your audio.
          2) Call someone on the repeater to verify your signal quality.
               If they can hear you, then all is fine.

Q:  Can this radio listen to Aircraft frequencies?
A:   No.   They are out of the radio's frequency range.
        Also, the Aircraft Band is AM while the UV-82 is FM only.
Q.  Can this radio listen to NOAA / NWS frequencies?
A.   Yes.  However, it cannot be put in a standby mode and triggered by
       their 1050Hz alert tone.

Q.  Why does my FM Broadcast Radio keep cutting out?
A.   The broadcast radio gives priority to an incoming VHF/UHF signal.
       It returns to broadcast  X  seconds after the signal clears.
       X  is determined by the ABR setting.  0-5 secs (0-24 secs using CHIRP)
      To prevent the radio from switching, set VHF/UHF to an unused frequency.

Q.  Why is my audio 'chopping' when listening to a station?
A.   If this occurs, STE (Menu 35) should be set to OFF.
Q.   Why does my receiver 'pulse' when returning from a received signal?
A.   This is a 'bug' in some firmware releases.
If Save (Menu 3) is set to 1, 2, 3 or 4 and ABR (Menu 6) is set to 9 or 10, a pulsing may occur on a broadcast FM signal when returning from a received signal interruption.
- Work Around:  Set Save to OFF  or  ABR to 8 or less.

Q.  What range can I expect from these radios?
A.  There are many factors to consider.  Power, antenna, antenna height,
     HASL (height above sea level), terrain, obstruction, trees, horizon, etc.
     A good starting point for simplex operation would be Distance_Calculator   
     Your Mileage may Vary.

Q:  I programmed a channel, but it won't save.
A:   There are three steps to the process:         
          1) You must be in the VFO/Frequency mode
          2) Display A (top display) must be selected.
          3) Channel must be empty before programming frequency data.
              (use menu 28 to delete a channel)     Refer to Programming Hints

Q:  How can I store a 7th digit of a frequency?    xxx.xxx5
A:   Change Step (Menu 1)  to 2.5 kHz.
      Enter the first 6 digits of the desired frequency, then use the
          Up/Down arrow for the last .5 kHz.
              Example: 462.7125 would be:     4 6 2 7 1 2   Up Arrow.
              A tiny 5 will show to the right of the frequency display.

Q.  Can I store different frequencies in A and B?
A.   No.    There is only a single bank of 128 channels (0-127)
      The same frequencies show in both displays A and B.
      You can however change the way they appear.    (Menu 21 & 22)
      The display options are Frequency, Channel Name or Channel Number.
   Manual programming of memory channels can Only be done while
   display A (top display) is selected.

Q:  What is the purpose of A and B if they are both the same?
A:   Dual Receive. You can set each to a different preprogrammed channel.
      With TDR (Menu 7) turned on, your radio will sample between the
          two frequencies and stop on whichever one has activity.

Q.  Can displays be synchronized to show Name in A and Freq in B?
A.   No.  Display A and B operate independently.

Q:  Can I disable the transmitter for Receive Only frequencies?
A:   Yes. This can be done using the transmit inhibit function of your software.

Q.  Can I store FM Radio 65-108MHz channels into memory?
A.   No.  This is controlled by a separate receive only chip in the radio.
       You also cannot make this radio transmit on this band.

Q:   How do I switch modes?  (VFO/MR)
A:   Press and Hold the [MENU] key when turning radio on.
Q:  My receiver skips over some channels when scanning.
A:   There is a known 'quirk' with the UV-82 receiver.
       If a scanned channel has an R-CTCSS (PL) tone of 136.5 Hz
            or lower, the receiver will not stop on that channel. 
       R-CTCSS (PL) tones of 146.2 and higher work fine.
Note:   It is recommended to Not use RX Tones unless absolutely necessary.
Note:   The scan rate of this radio is only 3 channels per second.

Q:  My radio only scans my top group of frequencies, but not all.
A:   Power cycle your radio ON/OFF and the issue should disappear.
Q:  Why can't I key or hear my local repeater, fire dept, etc. ?
A:   Some Repeaters and Services require a CTCSS (PL) tone for access but DO NOT transmit one back.  If your display indicates there is an incoming signal but you hear no audio, you may have an incorrect or unnecessary RX tone set.
This can be tested by pressing the [M] button. When in doubt, leave the RX tone OFF

Q:  What are these CTCSS (PL) tones I keep hearing about?  
A:   A CTCSS is an 'Tone' sent along with your voice when transmitting.
      They are used to access a specific repeater and block interference.
          Visit CTCSS  for details.

Q:  How do I transmit a 1750 Hz tone for repeater access?
A:   Press the [PTT] button and then press the [F] button to transmit
          a 1750 Hz tone.

Q:  What are the DTMF keypad positions for A, B, C & D?
A:        [Menu] = A   [Up] = B  [Down] = C    [Exit] = D

Bug Note: When sending DTMF tone D [Exit], the speaker tones as well as the tones sent over the air are those for 0 [zero].

Q:  Are cables, antennas, spkr/mic, etc interchangeable?
A:  Many accessories are, such as Kenwood / Wouxun.
Q:  Is a radio case a good purchase?
A:  It depends on your use. Refer to Radio Shut Down below.  See FAQ 111

Q:  Is there a Battery Eliminator for the car?
A:  At this time, there is no known Battery Eliminator.

Q:  Is there a USB charger for the UV-82?
A:  No.  The UV-82 battery has a 7.4 volt battery.
      A USB port is only 5.0 volt.
      The standard charger supplies 8.4 volt during the charge cycle.
      At 5.9 volts, the UV-82 announces a 'Low Voltage' warning.  See FAQ 104
Q:  What battery comes with my UV82?
A:   The battery supplied with your UV-82 is the BL-8.
      The battery is:   Li-ion  7.4V  1800 mAh.

Note:  Some batteries are shipped from the factory with labels showing Ni-MH (nickel–metal hydride) or capacities shown as 2800 mAh. These were printed in error by the battery manufacturer and not at the request of US vendors.

Q: Is there an alternative to the Factory software?
A:  An excellent alternative is CHIRP.  It's easy to navigate and new features are added on a regular basis.
     This can be found on the CHIRP Software & Examples pages.

Q:  Why must I load an older cable driver for Vista, Windows 7/8/etc ?
A:  Many generic cables use Prolific chip clones/copies.
        Windows will load the latest driver which rejects cables using cloned chips.
        This is covered in detail in the  USB Cable Drivers  page.
        These cables work fine if the proper driver is loaded.

Q:  How can I be sure I order a USB cable with an authentic chip?
A:   Programming cables utilizing an FTDI chip will work with no problems.
      Call your local dealer before ordering to confirm chip set.

Q:  Is there software that can 'Open Up' the freq range of my radio?
A:  Not at this time.
Q:  I have NO audio on Transmit
 First, confirm you have no TX audio by listening to your signal on Simplex. If you experience no audio, the microphone jack might be stuck open with debris. Trim a Q-Tip to fit the microphone jack opening and dampen with denatured alcohol to clean the jack contacts. Allow ample time to dry.
Why is my microphone audio is low?
A:   Here's are some suggestions:
         1) Talk directly into the radio, within one inch.
         2) Try an external spkr/mic to confirm problem is the mic.
         3) Blow compressed air into the spkr/mic jack.
         4) If yo
u have an external spkr/mic, plug it in and out a few times.
                 The issue might be a dirty connector. 
         5) Ham Bands Only - Set to Wide Band.  5 kHz  (Menu 5 = W)

Note: Some have reported the need to open up the microphone hole in the plastic case. This can be done by CAREFULLY using a 3/64" drill bit and twisting it slowly by hand to clear out the opening, but avoid touching the microphone. There is approx 1/16" clearance between the inside of the case and the microphone element. 

Q:  Why is the audio less sensitive than my Icom or Kenwood?
A:  The UV-82 series was designed as a commercial radio, not ham.
      It was designed to block out background noise in an industrial environment.
      Talking right into the face of the radio cures most audio weakness. 

Q:  Is the PTT switch disabled when a Spkr/Mic is plugged in?
A:  When a Spkr/Mic plugged in, the dual PTT on the Radio is still active.
      When the PTT on the spkr/mic is pressed, display B is selected.
      All audio comes from the spkr/mic only, regardless of which PTT is used.

Q:   What Speaker Microphone options are available for the UV-82?
A:  There are 2 optional choices.
     1. Single PTT Spkr/Micr - Always selects display B.
     2. Dual  PTT Spkr/Micr - Lower Side PTT selects B, Top selects A.

Q:   Will the UV82 Dual PTT Spkr/Micr work with a standard UV5R?
A:  Yes. However it will function as a standard single PTT Spkr/Micr.
      Only the Lower Side PTT will function.  The Top PTT button has no effect.
      Using a Dual PTT Spkr/Micr will not create a new UV5R function.
Q:  Which antenna is best?
A:   It's all personal preference, but a good rule of thumb is:
      The longer the radiator, the better the range, especially on transmit.
      Short stubby antennas use a coil to match TX to 50 ohm, not radiate.
      The closer to 1/4 wavelength in the air, the better the performance.

      A field test was performed between 31 popular antennas.
     The results can be found HERE.

Q:  Can I use an antenna with an SMA RP connector?
A:   No. The RP stands for Reverse Polarity. The outer shell looks the same
but the Male/Female pin sequence is reversed.   SMA Female

Q:  My antenna doesn't screw in all the way.
A:   This is not uncommon on some aftermarket antennas. Purchase a thin 5/8" OD rubber O-Ring.  Take your HT with you to the hardware store to assure the proper fit.  You may want to superglue it to the bottom of the antenna ONLY Extended_Threads

Q:  Can I build my own antenna?
A:   Absolutely.  If you want to start small, try a simple ground plane.
      Here are the instructions for a GP antenna with a radial length calculator.
      The calculator covers all frequencies from DC to Light.  CALCULATOR
      A great project.
Q:  Display goes dark if I talk too long on Hi power.
A:   This is to be expected from a small radio.
          5 watts creates a lot of heat in a small unvented area.
          Give it time to cool down.  The LCD will return to normal.
          The same occurs if you leave the unit in the car on a hot day.
          Run low power whenever possible. This will also extend battery life.

Q: Why does my display show + and - at the same time.
In Channel Mode this is normal when the TX / RX frequencies differ,
In Frequency Mode  + or - is displayed based on Menu 25 (SFT-D)
If TX and RX are the same (simplex) the + - indicator does not display.

Q:  How accurate is the S-Meter?
A:   The What?  There's a signal indicator in the upper left.
       If there's a signal, it appears.  If not, it's gone.

Additionally: The signal indicator even shows full deflection on an unused channel when you (a) press the monitor button, or (b) when you set the squelch level to zero.
Q:  Why doesn't the S-Meter function in a normal fashion?
A:   The SDR receiver found in the UV-5R & UV-82 series does not measure an incoming signal in the traditional fashion based on strength, but rather the amount of noise. Once the signal becomes Full Quieting, it cannot determine the difference between an S1 or S9 signal. Unfortunately, this is by design.


Q:  How do I translate the Battery indicator in the upper right? 
A:   Tests have shown the following:        
(tests by Phil Souza)
       Full charge (approx 8.32 volts) 3 bars
       Battery drops to 7.09 volts, 2 bars
       Battery drops to 6.73 volts, 1 bar
       Battery drops to 6.29 volts, 0 bars
       Battery drops to 5.91 volts,
          the radio announces "low voltage" until the battery expires.
       Note: Measurements can vary based on temperature and load.

Q:  Why does my display disappear if I wear polarized sunglasses?
A:   LCDs function by polarizing the liquid crystal elements in the display.
       Polarized sunglasses will react to the polarized lens.   
LCD Wiki
Q:  Why did my radio shut down when I took it out of my pocket.
A:  If you carry your radio and keys in the same pocket, a case is recommended. If the charging contacts are shorted, the battery goes into the protection mode. There will be no damage to the radio, but it will power off. To reset the protection mode, the battery must be removed and reinserted.
Note: If you carry a spare battery, place it in a plastic bag for protection.


Q:  Did I get a used radio?  My UV-82 had frequencies pre-programmed.
A:   No.  Your radio is new.  These are channels used for factory testing.
      The easiest way to remove them is to:
       Press Menu, 41 (Reset), Menu, ALL, Menu.
Q:  My radio doesn't speak English?
A:   Press  Menu, 14, Menu,  Make selection,  Menu
        Options are:   CHI / ENG / OFF
Q:  How do I lock/unlock my keypad?
A:   Hold the  #  key in for 2 seconds.
       Pressing it quickly alternates TX power level.
Q:  Where can I get a User Manual and Schematic for this bad boy?
A:   Here is a link to the  User's Manual  and  Schematic 
The enhanced manual for the UV-5R is covers 98% of what you need for the UV-82, but goes into much more detail.
