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 this radio 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 is my audio 'chopping' when listening to a station?
A. If this occurs, STE (Menu 12) should be set to OFF.
Q. Why is my volume so loud? Is there a fix for this?
A. The good news is that there is a fix for this.
Follow this link to Audio Mod.
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.

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: 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: Are the UV-3R and UV-3R+ antennas the same?
The UV-3R requires an antenna with an SMA-Male connector.
The UV-3R+ requires an antenna with an SMA-Female connector.
The UV-3R+ and the UV-5R antennas are interchangeable. SMA_Female
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. 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.
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 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
