TRANSMITTER and RECEIVER
21 Q: I can't key or hear my local repeater.
A: Review the Tone Access section of this page.
22 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.
23 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.
24 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.
25 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.
26 Q. Why is my audio 'chopping' when listening to a station?
A. The bandwidth settings (Menu 5) should to be set to WIDE.
27 Q. What range can I expect from these radios?
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
Your Mileage may Vary.
31 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)
32 Q: How can I store a 7th digit of a frequency?
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
tiny 5 will show to the right of the frequency display.
33 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.
34 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
With TDR (Menu 7) turned on, your radio
will sample between the
two frequencies and stop
on whichever one has activity.
Can displays be synchronized to show Name in A and Freq in B?
A. No. Display A and B operate independently.
36 Q: Can I disable the transmitter for Receive Only frequencies?
A: Yes. This can be done using the transmit inhibit function of your
37 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.
38 Q: How do I switch modes? (VFO/MR)
A: Press and Hold the [MENU] key when turning radio on.
41 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.
42 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.
TONE ACCESS (CTCSS, DCS, DTMF)
51 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
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
This can be tested by pressing the [M] button.
When in doubt, leave the RX tone OFF.
52 Q: What are these CTCSS (PL) tones I keep hearing about?
A: A CTCSS is an 'Tone' sent along with your voice when
They are used to access a specific repeater and block
interference. Visit CTCSS for details.
53 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?
[Menu] = A [Up] =
[Down] = C [Exit] =
When sending DTMF tone D [Exit], the speaker tones as well as the tones
sent over the air are those for 0 [zero].

See FAQ 111
Is there a Battery Eliminator for the car? A: At this time, there is no known Battery Eliminator.
65 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
At 5.9 volts, the UV-82 announces a 'Low Voltage'
warning. See FAQ 104
66 Q: What battery comes with my UV82 / 82X have?
A: The battery supplied with your UV-82 / 82X is the BL-8.
The battery is: Li-ion 7.4V 1800 mAh.
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.
71 Q: Is there an alternative to the Factory software?
A: Most users prefer 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.
72 Q: Must I load an older cable driver for Vista, Windows 7 & 8
A: Many bargain cables came through with Prolific chip clones/copies.
Windows loads the latest
driver which rejects these 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
A: Programming cables utilizing an
FTDI chip will work with no problems.
Call your local dealer before ordering to confirm
Is there software that can 'Open Up' the freq range of my radio? A: Not at this time.
MICROPHONE & AUDIO
81 Q: I have NO audio on Transmit A: If you experience no audio (after confirming on
simplex), 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
4) If you have an external
spkr/mic, plug it in and out a few times.
The issue might be a dirty connector.
Bands Only - Set to Wide Band. 5 kHz (Menu 5 = W)
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
83 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.
84 Q: Is the PTT switch disabled when a Spkr/Mic is plugged
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.
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 or 3/4 wavelength in the air, the
better the performance.
A field test was performed
between 31 popular antennas. The results can be found
92 Q: Can I use an antenna with an SMA RP connector?
A: No. The RP stands for Reverse Polarity. The outer shell looks the
but the Male/Female pin sequence is reversed.
93 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.
94 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
A great project.
101 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
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.
102 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.
103 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.
104 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.
105 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
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. 106 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
111 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
Note: If you carry a spare battery, place it in a plastic bag for protection.
112 Q: Did I get a used radio? My UV-82 had frequencies
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.
