Great radio to get started with DMR

Purchased as my first DMR rig, I was looking for a unit that had GPS capability, as well as VHF and UHF on both DMR and FM. This unit fits the bill perfectly. Included programming cable worked great with my Windows 7 machine and I was able to download the software from the Retevis website. Seems like Retevis is really going out to help Hams get on DMR, which is great. After using this radio for a week, I will say that programming DMR from scratch is not easy, however it is doable. The Retevis software is easy to work with however I will recommend a large monitor. Using a 12" laptop for programming is possible, but not easy. I know a lot of folks complain about the trackball, but once you are used to using it, it's really not that bad. You can program side buttons to do the same functions so it's not necessary to use the trackball. It's semi-protected from accidental use by the circle with arrows around it. Only semi-protected though; it is easy to brush with your fingers when grabbing the radio. Reception using the stock antenna is on par for the antenna of it's size, on FM. On DMR reception is incredibly clear, as it's digital. Audio is nice & loud on the internal speaker; I've had no trouble listening either indoors or outdoors. For me, the radio is a tad large however I'm used to a UV-5R which is substantially smaller. It's definitely solid though and the buttons have a great feel. The screen is nice, bright and easy to read; however it is not dimmable (currently) so i

Four Stars

Can't beat it for the price

Best radio to transition to Dmr and have a dual mode HT at hand.

Excellent radio, not only dual band ( programable) but dual mode. Perfect transition from analog system to the digital world. Code plugs are available online and easy to customize. Price and accessories make it a no brainer for any ham looking for a do it all handy talkie.

I find the RT82 easy to use after a short learning period

I find the RT82 easy to use after a short learning period. My audio reports are good and the audio I get from the radio are very good. It feels good and sturdy in my hand. I like being able to monitor/talk on both VHF and UHF, DMR and Analog. I use CPS2017 software to program it and seems to work great. The only reason I don't give it 5 stars is that so far I have been unable to find where to purchase just the battery for the RT82. UPDATE: Changed to 5 stars, since I was able to get a spare battery.

Solid build, great customer service

This is one chunky little radio, very solid feel in the hand and very good audio quality. When you get it don't forget to load the current firmware (it's easy). Also be aware the programming software will occasionally forget to save to file the contents of a zone, so be aware and keep extra backups on hand. I'm using it on both amateur bands, DMR and also on the marine band for kayaking. I had an issue with an external mic and contacted their customer service and they quickly resolved the problem, good folks.

Great radio, hard to program

I really like the radio, but it has a really steep learning curve for programming.

I find the radio to be great

Received, inboxed and field programmed this radio; did not have computer handy . I find the radio to be great, so far! It is a great design and packaging a great size to hold on to, just an overall great form factor. Using it on amateur frequencies for my groups 'Net' night last night , was told I have a good strong clear signal with the rubber ducky antenna that came with it , much stronger signal than my RT23 5W which I had used previously to talk to the same people. Hitting repeaters 16 to 20 miles away with the rubber ducky. Was told my signal came in full quieting and was totally impressed with both receive and transmit of this unit . Did have some trouble "field programming ", can only get it to lock in one repeater at a time, or one simplex frequency at a time ; not using the computer to program it seems to override the previous channel I had programmed. I am sure that it is just a matter of not using the computer program to enter the frequency information. Can only program on Repeater or simplex channel in “field” without computer by design. Definitely need computer for DMR, their software is easy to use. Have yet to be able to find a code plug for it; but have programmed over 100 Repeaters and simplex channels both in DMR and Analog. Nice form factor and easy radio to use.

Missing parts, resolved!

this is a great little DMR radio

The trackball is tricky to get used to and is a bit out of place on a portable radio. I would subtract a star for the trackball but, honestly, this is a great little DMR radio. Good battery life, well built, and the programming cable was included which makes it easy to set up. Just go to the Retevis website to download the latest software and firmware, then build your code plug and go. Don’t forget to register for your DMR ID so that you can access the system (yes, you need an ID beyond your FCC call sign to get on the digital nets). In analog mode, this radio works about as well as any of the new crop of budget radios. No complaints at all.
