New Radio – Baofeng UV-82

Thanks to Lewis over at Distant Signal Radio, the bad influence he is on my bank balance ;), I’m the proud new owner of a new Baofeng. This time it’s the UV-82.

This radio is a little different from the other Baofengs I have. Here are the main differences:

  • Dual PTT – This one is going to take some getting used to 😉
  • Higher capacity battery pack
  • A more rugged, commercial feel

This radio has a different method of selecting the VFO mode – holding the menu key while the unit is powered on. This is a little awkward, but since I only usually use my local repeaters when I’m mobile, it’s not much of an issue.

Here’s the radio itself, it has a much more commercial feel to it than the UV-5Rs, and it’s slightly bigger. Mainly due to the use of a larger standard battery & larger loudspeaker.

Back of the unit with the spec label. As per usual Baofeng are a bit conservative with the power ratings, more to come on that below.

Here’s the battery pack, a 2-cell lithium-polymer unit. This has a bigger capacity than the standard UV-5R battery, at 2800mAh.

Here are the power settings as measured by my GY-561. Frequencies used are 145.500 & 433.500

 

VHF High: 7W
VHF Low: 2.5W

UHF High: 6W
UHF Low: 3.1W

Baofeng UV-5R Manual Programming

I’ve always found programming repeaters into the UV-5R manually a bit of an arse, especially since the manual is pretty poor & very concise. Ringway Manchester have done a very good video detailing a simple way to get this done without a computer & most importantly, without any headaches!

Baofeng UV-5R RF Power Measurements

I’ve noticed that the RF power output from the Chinese radios can be quite variable from model to model, and even from individual radios of the same model & batch.
I’ve bought an RF Power meter (GY561) to do some tests on the HTs I have at present.

All tests were performed with the radio fully charged & still on the charging base, to make sure the supply voltage remained constant at 8.4v throughout the tests.
Frequencies used were 145.500 & 433.500 for VHF & UHF respectively.
The power meter was connected with ~8″ of RG174 Coax.

 High Power:

UV-5R 1 (S/N: 13U1136132):
VHF: 6.3W
UHF: 4.9W

UV-5R 2 (S/N: 13U1136114):
VHF: 6.5W
UHF: 5.2W

UV-5R 3 (S/N: 130U541416):
VHF: 7.1W
UHF: 6.3W

Low Power:

UV-5R 1 (S/N: 13U1136132):
VHF: 2W
UHF: 1.2W

UV-5R 2 (S/N: 13U1136114):
VHF: 2.3W
UHF: 1.5W

UV-5R 3 (S/N: 130U541416):
VHF: 2.7W
UHF: 2.1W
