These are an economical Dual Band UHF/VHF Amateur Radio. The UV-82 series of radios feature a rocking Push-to-Talk button which allows you to transmit on two frequencies depending on how you push the button. By pressing up you can transmit on "Frequency A" and by pushing down you can transmit on "Frequency B".

Improvements over the Baofeng UV-5R include a louder speaker (1 watt), rugged case, larger buttons, and more powerful control processor. The radio barrows from design qualities of commercial Part 90 radios. The battery compartment has better contacts to prevent issues common with older Baofeng radios during off when the battery contact became intermittent.

Manufacture or distributor name variations include: Baofeng Pofung UV82 UV82X

There are variations of the UV-82. Some are listed here:

• Baofeng UV-82 - Dual Band VHF/UHF TX 136 - 174MHz, 400 - 520MHz for ham / amateur radio
• Baofeng UV-82C - Dual Band VHF/UHF TX 136 - 174MHz, 400 - 520MHz, VFO disabled, C "Commercial" claims to be Part 90 type accepted
• Baofeng UV-82L - Dual Band VHF TX TX 136 - 174MHz, 220 - 260MHz for ham / amateur radio (possibly a UHF variant also available)
• Baofeng UV-82X - Dual Band VHF TX TX 136 - 174MHz, 220 - 260MHz for ham / amateur radio (unknown if exactly same as 82L)

• NOTE: Not the same as the Baofeng UV-82 V2+ Tri-Power
• NOTE: The UV-82C disables VFO operation. Programming is done with software. It is possible to enable VFO with software.
• NOTE: There are UV-82L models that are dual band VHF/UHF TX 136 - 174MHz, 400 - 520MHz which appear to be identical to the UV-82 model. Chinese model designations are inconsistent. This is typical with Baofeng Pofung import radios.

• 128 Channels at 25KHz (wide band)12.5KHz (narrow band)
• Sensitivity ≤0.25μV (wide band) ≤0.35μV (narrow band)
• Operates at 7.4V DC ±20% from a 1800mAh
• Frequency step selection of 2.5, 5, 6.25, 10, 12.5, 20, 25, 30 and 50KHz
• Relative xmit power depends on model, standard is 5W / 1W or 2W on 220
• Audio Power Output 1000mW/10% (1 Watt)
• CHIRP compatible

Review

They are not manufactured to the standards of Kenwood, Icom, or Yaesu, however, for a fraction of the price they have a good place in the market for those on a budget. This is especially useful for a small business wishing to purchase quantities. The battery connect improvement should make them far more reliable than the UV5r. The ability to set them to channel mode only makes them useful for business.

The Baofeng UV-82L model was discontinued due to strong harmonics. When used on 1.25 meter the radio emitted on 70cm also (splatter) beyond acceptable limits. Also, the menu was flawed as the Chinese labelled 1.25-meter operation as UHF, which is incorrect as the band is within the VHF spectrum.
