New Tytera MD-390.

[Project25_MASTR]

No Dual Band (In China that may mean ANALOG AND DIGITAL) which it does.



GPS is a big Questiona, Tytera says Yes, but they said the same thing on the 380, and it doesn't have GPS.



The one guy in Indiana is now selling at $175



Will be looking at Tytera on Wednesday at IWCE, get a "Demo"!

Let us know what you find out. I have to ask Hytera questions about trunking, find out about the Tytera 100W repeater and see if I can't spend some time with ether stack.

Looks like we'll have a Simoco repeater running up in the conference rooms.

I had some tyt radios before, anyone have this radio in VHF? I need to know before I get one if it will take 151.5125 and 158.4075, one tyt I had wouldn't take those two frequencies.

I like this radio so far from the reviews, i'd like th MD-390 to be out in VHF but nothing out yet.

I just got on DMR this week. I bought a Tytera MD 380 with all the extras less than 6 months old. DMR is another form of ham radio for communications. So far I like it.

MD-390 GPS DSDPlus test results

I got an MD-390 w/ GPS in the mail today and thought I would share some test results with the forum...

Photos are here https://www.flickr.com/photos/reffahcs/albums/72157670327492405

So bottom line, the GPS works.... sort of. It does have a GPS receiver built-in that uses the main antenna (similar to what Hytera does). The Satellite UnLock screen just means it hasn't acquired GPS lock, not that the GPS function needs to be unlocked, which is what I thought at first.

I say the GPS sort of works because you can look at the DSDplus screen shot and see that no GPS data was decoded. You can see it being received though, they are the two lines in the log that says DCC=1 Data Header followed by Rate 1/2 Data. I also uploaded a screen shot of the GPS burst captured via SDR#.

As far as CPS options go, you can enable GPS TX/RX per channel as well as and automatic GPS "ping" where it will transmit on a specified channel to a specified user at an interval of your choice. You can only send the pings/beacons to one specific ID, so either one talkgroup or one radio id. That's about it for GPS options in the programming software. If anyone wants to see screen shots of this let me know, but I'm assuming people have already seen these since the software is freely available?
I don't have another MD-390 to test the GPS transmit/receive with but we just got in some Hytera 785Gs at work so I might borrow one to do some testing over the 4th of July weekend.

Well hopefully that answers some questions about the GPS function of the new MD-390. Let me know if you all have any other questions about the MD-390 and it's GPS and I will try my best to help answer them.

I purchased an MD-390 Last week and the radio works great. Although I did not get the GPS module - did not know it was a different model. also I was told the 390 comes in a duel band with is also a slightly different model.

The problem I am having is that the radio clock stops when you turn the radio off and starts up again when you turn it back on. so the date does not change if the radio is off. I was told by the company I purchased it from and was told it is a firmware issue . Does anyone know where to get the new firmware from. I have Firmware Ver D013.009 CP ver. : V01.30

I was directed to the firmware for the 380- which the tag on the radio says it is a 380, for firmware but the numbers don;t match. Anyone have any idea what the proper firmware is and where I can get it.

Thanks

MD-390 firmware

Looking at Tytera's website I don't see any firmware for the MD-390.... Might still be a little too early for a first release.

I'll check my MD-390 tomorrow and see if it has the same bug you were talking about with the time.

MD-390 clock

I checked my MD-390 last night, I didn't have any issues with the time or date. I turned it off for several hours (with the battery still in) and it was good. I tried it with the battery out as well, for maybe an hour or so, no issues, the clock was right on when I turned it back on. I left it off over midnight too and the date changed just like it was supposed to.

Perhaps it's a firmware issue only related to the non-GPS 390? Could also be an issue with the rtc battery/supercap--whichever it uses?

I'll bet if you remove the battery and the clock resets there is no battery and it just gets it from GPS and maintains it if there's battery power.

 

[rsiena]

Can you go the the information section of the set up and tell me what your firmware version is?

mine Firmware Ver: D013.009
CP ver. : V01.30

Thanks for checking

MD-390 clock

The MD-380 has a 32.768 KHz crystal on the schematic (https://github.com/pchickey/md380-re/blob/master/datasheets/MD-380UHF-RF-schematic.pdf). I would have to assume this is for the RTC. If the MD-380 has an RTC, you would figure the MD-390 would as well?

I did my testing indoors as well... The GPS receiver is not very good on the MD-390 and even at it's best it takes a minute or two to acquire GPS. If there was no battery/supercap for the RTC, I don't think the MD-390 would be able to acquire the time from GPS before you would be able to go through the menus to look at the clock.

The clock gets the Date/ Time from the GPS (to)? If yes thats an fantastic news!

So i think you play arround with GPS can you tell me more about?

 

[softballfreakmom]

Hi. New here and looking at getting this radio as my first starter radio. I was told it does HAM and it also can do GMRS is this the case?

Also how does one set up an out door antenna for at home for this radio?

Very new to this world. I also read about repeaters. Do you program the radio for the said repeaters?

 

[teufler]

i HAD A TYT 390 GPS WITH VHF. bIOUGHT THROUGH AMAZON.

 

[teufler]

THROUGH THE SOFTWARE, you can program anything from 400-480 or 136 to 170 in the vhf spectrum. You get an sma to s0-239 adapter, about $3-$4 dollars. You can also buy a patch cable, that allows this connection. Personnaly, I just hook up and lay the radio on the seat or put in a cup holder and use an external speaker mic.If you use the radio at home , with an external anrtenna, just pout the radio in the desk charger , put some velcro on the bottom of the charger so it doesn't move around, and use a speaker mic.

I was told it does HAM

You are an Radio Amateurist (with a Callsign)?

Not yet. Probably going to happen in the year or next and I want to be sure I get all the correct information before I go spending any sort of money.


I wish not to be bashed in any way shape or form if that is ok

Don't worry, some of us understand that folks want to learn before spending money, and that not everyone that is licensed is comfortable with using their callsign as a forum handle. Hope to hear you on the radio when you do get your license.

But its not legal to transmit on a Radio Amateur Freq. without a Licence.
So in fact he cant transmit legally with this Radio (at the moment).

Wasn't planning on it. Was planning on getting all squared away in the license department before getting the radio.

I just wanted to know if it could do both Ham and GMRS frequencies.
