TYT MD-380 / MD-390 Experimental Firmware Features Explained

TYT MD-380 / MD-390 Experimental Firmware Features Explained
I just wanted to highlight and comment on some of the features added to a TYT MD-390 DMR radio after flashing a modified firmware. I'm very new to DMR so I'm just sharing what I've learned (or think I've learned) in just a few days.



MD-390 Program Pre-set Buttons

I programmed the upper side button for zone toggle. It will only toggle the first 4 zones. I have 7. How can I get it to toggle through all 7.

I am talking about the upper side button (above the PTT)' not the keyboard.

Please help with your comments

Fran MD390 return button

Hi. My name is Fran , my indicative EA4FRI . I am writing to you because I see you have experience in DMR systems. I'm starting to experiment with the DMR system. I bought a DV4mini and TYT walkie MD390 . It has everything very good. It turns out that I meet a somewhat strange problem is that the return button (red button) does not answer me . I tried it with "short" press and long press and unresponsive. Do you know of any similar problem ? What can be ? I sent a video on Google Drive. Thanks for your attention.

Tytera MD-390 vs MD-380

I have been pondering or not to purchase a MD-390 or 380.  I am wanting to get into DMR but I have not made the move yet. I wanted to start off with a handheld unit and then over to a Mobile radio.  I have 2 questions mainly.

1. What advantages does the MD-390 have over the MD-380 other than being water proof?  Looks like the MD-380 will do the same things the 390 will other than has a larger battery and is water proof.  Anyone know?  Also for the price difference I was just curious.  Even at $199 for the 390 it's not a bad deal.

Also with either radio, does anyone know if there are any AA battery holders available to use with it?  I was just wondering on this?  It would be nice to have the ability to use a AA batter holder on the unit in the event of your main battery being dead. Anyone know?  I would prefer a radio that has this capability if possible.

I have posted a video on the TYTERA MD-390 being submerged under water( for its baptismal).

Like its counterpart in the watch industry (TIMEX), the new DMR member of the TYT family still " keeps on ticking"!

MD-390 is a MD-380

Many people feel the MD-390 is a MD-380 in a different case. The FCC # on both radios is the same. If the 390 was different, wouldn't it have it's own FCC #? The fact that the same CPS programs both radios doesn't mean much, as the same Moto CPS programs all Moto Trbo radios.

Manufactures often make small changes to the PCB without getting a new FCC number. In this case the PCB might be a slightly different size even though the electronic design might be the same. There might also be some slight electronic differences. This is not to say it is legal under FCC Part 90 rules but that is the reality of what happens. From a practical viewpoint, if you have to add a resistor to the PCB because of some slight design defect, it is not reasonable to have to wait months to get new certification. I will also be willing to bet that some manufactures will take the FCC ID number from a competitor or even their own products and assign the same number to a completely different product.
