About the RT3 radio:

MD380 Tools is an experimental firmware for the TYT MD380/390 series DMR transceiver for the purpose of adding enhanced features. It was originally developed by Travis Goodspeed KK4VCZ with ongoing contributions from fellow hams. The update adds over 16 features not found in the original radio, including the ability to load the DMR User Database. I am using a Macbook with Mac OS and that makes it challenging to get Tyteras programming software CPS to run, which is a Windows application. TYT MD-380 Tools: A.

RT3 is a VHF(136-174Mhz)/UHF(400-480Mhz) DMR radio. Fashion design, good quality and low price, all make RT3 is a good choice for hams to use the Digital radio. With 1000 channels and 16 color Codes and 259 CTCSS/DCS Codes, totaling 272,000 combinations, it is easy to find an available channel.

High/low power (5w/4w),

Remote kill/stun/activate,

Voice prompt,

Power-on protection,

Text messages in digital mode,

Encryption function,Built-in CTCSS/DCS,

Priority scan,

Complying with digital protocol ETSI TS 102 361-1,-2,-3,

DTMF decoding and encoding,

Private call, group call,all call in digital mode,

Operate in both Digital & Analogue mode,etc.

All those functions make RT3 is suitable for hams. Updated software available for new features, When there is new software we will update it on our website, you can download here. When there is new firmware we also can provide the newest firmware.

About the MD380 TOOLS Firmware:

There are some very professional hams are not satisfied with the existing function. They do some revise for RT3’s firmware and do another firmware MD380 Tools. If you are interest, you also can try it with RT3. It will give you another DMR radio experience. Here i will introduce some new function of MD380 Tools.

1.It can make your radio storage more contacts information (you can imput the contacts list by .csv file directly. very convenient), and when some one calling ,you can see more on your radio lcd.

2. Change Date Format to: Alt. Status.
It’s all the way down at the end of the scrolling list of date formats. This turns off the Date and Time display and shows you Last Heard information instead. Trust me, you will like this. You will notice the date and time display will be gone, to be replaced by: “lh” followed by the call sign, and an arrow pointing to the Talkgroup number they were using.
3.Mic Bargraph: Enabled
This enables a cute flashing VU Meter when you are transmitting. Use it to see how hot your voice level is and adjust your mouth-to-radio distance or voice to make it consistent. Digital radio voices that are too hot sound awful, so use this feature as a reference for good operating practice.
4.Edit DMR ID:
You can now change the radio’s DMR ID without using the CPS software. Handy if you need to switch identities in the field.Some very interesting hidden features can be enabled under the Utilities MD380Tools menu. Scroll down to DevOnly!! and enable it. I believe you need to have Promiscuous mode enabled as well. This enables hidden menu items that are accessed with the single digits of the numeric keypad.

Here are the most interesting items:

8: Display screen one of diagnostic information . This screen displays some interesting data including current channel, zone, and talk group number. There appears to be an RSSI value, with normalized values from 1 to 5. There is an open ticket with the MD380Tools group to change this to display RSSI in dBm in the future.

9: Display screen two of diagnostic information. This screen displays calibration values for current power level, the TX and RX frequencies, color code, time slice and talk group name.

4: (Netmon4) Display the last 10 stations heard. Includes a time stamp, and the talk group heard on. An asterisk * at the end of the line indicates heard on your current talkgroup, an exclamation mark (!) indicates that station was heard on different talkgroup from the one you are currently monitoring.
5: Clears the list displayed in option 4 above. In an upcoming firmware release, this button will have called Netmon5, and will have new functionality.
3: Temporarily changes the current talk group that the radio will transmit on to the talk group the last station heard was using. This is of particular interest to those using the promiscuous mode. If you are monitoring stations with promiscuous mode enabled, you may hear stations come through that are not using the talk group your radio is currently using on the selected memory channel. You can press “3” on the keypad, and go directly back to the station you last heard. This works very well if you are using a hotspot device or hear something on a repeater but don’t have that talk group in a memory channel.
#: Displays heard list similarly to option 4, however displays DMR ID and talkgroup, instead of callsign. Green: Brings up the normal Menu of items. Allows changes in any of the normal items, but the Back (Red) does not function to exit the Menu. Press any of the other hidden menu digit access buttons to exit from the menu, and back to the hidden screens.
7: Exits from the hidden diagnostic screens.

Though I have introduce so many functions of MD380 TOOLS, If the RT3 already satisfy your basic requests. I do not recommend you to upgrade. If you upgrade to MD380 Tools, you will can’t revert to factory settings or factory firmware. MD380 tools writed by hams and it is free, they are very professional for radio. So I do not recommend you to upgrade avoiding mistakes when upgrading.

About how to upgrade RT3 with MD380 TOOLS, this is the method writed by Mark (VE3PZR). this method is simple but the users list is not the newest.

http://www.foxhollow.ca/DMR/?menu=experimental

Another method is a little complex. But all the information is newest. If you want to upgrade RT3 with MD380 TOOLS on Windows system. You need to run it on a Linux Virtual Machine. It need to download three .exe files. there is an guidance wrote by Warren Merkel, KD4Z. If you want to learn more you can watch this link. http://www.radioamatoripeligni.it/i6ibe/rt3/firmware/kd4z/kd4z.htm

Learn more details of MD380TOOLS you can click this link by KD4Z, Project page – learn more and get the PDF documents: https://github.com/KD4Z/md380tools-vm

Retevis is a Radio company, we have all knids of radio, analog radios, digital radios, childredn radios, business radios, mobile radios,etc. You must can find a model suitable for you. Retevis company has another new sub-brand Ailunce, it is mainly for hams. the first model HD1 is a dual band DMR radio. it not only save the RT3’s functions but also directly increase some MD380 TOOLS’s functions. It is also a good choice for hams.

At last i want to say again, though I have introduce so many functions of MD380 TOOLS, If the RT3 already satisfy your basic requests. I do not recommend you to upgrade. If you upgrade to MD380 Tools, you will can’t revert to factory settings or factory firmware. So think twice before you upgrade it.

Programming Your TYT MD-380 HT

OK so unlike many simpler & analog radios, you can’t just type in the frequencies you want to use into the keypad and off you go.
Instead, you must run communication software that will set the repeaters you will be using.
You can assign various repeaters to up to 16 different channels.
You can also program in analog frequencies (both simplex & duplex)

The good news is once you get your software file lined up, you can constantly tweak and re-program your radio
until its just the way you like it.

You’ll use the official TYT interface software to update the settings, download and install from http://www.tyt888.com/

Uncompress and install

It’s not signed, you may have to turn off program signing on your computer!

Once installed, run…

You’ll get a ‘default’ setup like so:

Turn off the radio, plug your radio into the programming cable, then turn on. Make sure it shows up as a USB device. Now select Read Data

Check that you have the STM DFU driver, not the libusbK driver installed

Now you have a ‘blank slate’ to work with, which is the default ‘codeplug’

If you by chance need to ‘start over’ with a blank original setup, this is the default codeplug file: Southpark season 7 download torrent.

Remember that ID number you got earlier? Now’s the time to use it. Type it into the General Settings window under Radio ID

As we determined, K2MAK is a good place to start so let’s program in this repeater that covers all of Manhattan:

This repeater carries

• Group 1 (World wide)
• Group 13 (World wide English)
• Group 3 (US + English / North America)
• Group 3172 (North East)
• Group 2 (NY-NJ Metro)
• Two TAC groups (wont be covered here)

We’ll enter all of these in as optional ways for us to communicate with others.

Go to the Digital Contacts window, to start it will have only “Contact1” which is group call ID #1

Click Add at the bottom to add a bunch of empty slots, then fill each slot with the Talk group and TG ID #

The blank/new codeplug has 17 Channel slots. Note that these aren’t necessarily ‘hardcoded’ to the channel selector, you can change zones to change which channels are used. In fact you can have dozens of Channels, split between zones. For now, though, we’ll only keep the first Zone and set up one channel per talk group.

In general:

• Each channel is for a specific repeater and talk group
• You can have a different repeater/TG per channel
• You can change out all of the channels when you switch zones. So, if you are often in both NY and Texas, you can have a fully different set of repeaters and channels you switch between!

However, we’ll start with just once channel for talk group 2, on the K2MAK repeater.

Set Name and Frequency

Let start by defining this to be the K2MAK NJNY Region channel:

The midtown Manhattan, NY repeater that is part of the Bronx-TRBO network. The Repeater Transmitting frequency is 448.2750 MHz and the Repeater Receiving frequency is 448.2750 – 5 = 443.2750 MHz

That means we should set our channel RX to 448.2750 and the channel TX to 443.2750

You’re not done! You next have to program in the Color Code for the repeater as well as the time slot. You’ll get this info from the repeater as well:

This goes on the right hand side, in partular m ake sure you have the right Color Code and Repeater Slot to match the Contact Name. The remaining you can set to None

Once you have the frequencies for your repeater set up you can speed things up by copying one channel:

and pasting it onto another. Note it will delete what was in the channel you’re pasting into

This time, I’ll program in the NE Regional, which is on Timeslot #1 so don’t forget to change it!

I’ll do the rest, ending with Worldwide. I set this to RX only so I dont accidentally TX on it!

That’s it! You’re ready to upload the data to your radio. Don’t forget you can always go back and mess with your codeplug and then re-upload it if you make a mistake or want to have more repeaters or contacts
