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: 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.
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 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
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.
Q: 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 you 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 - Top PTT selects A, Side PTT selects B.
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.
The Side PTT will select display B while the Top PTT will have 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 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 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.
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
