PROGRAMMING THE RT3 FOR AMATEUR FREQUENCIES（一）
Please Note: Because of its length, the article is divided into two parts. It is from W3HEN, It should be useful for new hams. At the end of the article, we attached the relevant video for reference.
Now We are going to study how to programming the rt3 together!
Step #1 – Charging the Radio and Browsing the Manual
The RT3 comes with a cradle charger and AC adapter. Several hours were required to fully charge the radio.
When fully charged, the red bar on the charger will change from red to green. The manual is reasonably well written and all 98 pages are in English.
While reading the manual is more important than on most analog radios, I’ll endeavor to get you on the air without reading it.
I do recommend that you read the radio eventually, especially if you attempt to manually program the radio using the Windows programming software.
Step #2 – Obtain Unique DMR Identification
In great part, unique DMR identification numbers are distributed by DMR-MARC.Net. MARC stands for Motorola Amateur Radio Club. Since receiving your identification number can take a couple of days, I was tempted to make this step first on my list. All of your DMR transceivers will use the same numeric identification code.
Step #3 – Download & Install RT3 USB Drivers and Programming Software
Download USB drivers for the provided Retevis USB programming cable from Retevis.Com. The same site contains the RT3 programming software. Both files are contained within archives. Once uncompressed, run the driver followed by the programming software under Windows. I used a Mac Pro running Windows 7 Ultimate.
Step #4 – Locate the DMR CodePlug for your Region
Because DMR radios are much more difficult to program than analog amateur radios, most use a prepared programming data file that was prepared by others with much higher levels of expertise in DMR manual programming. A Google search for “DMR Amateur Radio Groups” may well locate the best source for the preprogrammed DMR data file for your area. Another course would be to ask fellow amateurs in your area for the site address. I choose the latter and accordingly downloaded the data file from VolNET, which contains repeaters and simplex frequency parameters for the eastern half of Tennessee. DMR is popular throughout the world and is widely supported by amateur radio groups.
