MD380 out of band reception

I have worked out how to program out of band. I have been able to enter RX freq upto 498.000mhz.
Change this in the setup.ini

Original value is

freq2=[400-480MHz]
data2=00400048

Change to the following
freq2=[400-520MHz]
data2=00400052

The last two numbers determines the frequency.


You can then enter any freq from the keypad you like upto around 498.

My radio works really well.

The only problem is that when you program your radio using the software it will only only you to enter VHF 136 - 174.

If you ever want to go back to original just change the values in the setup.ini back to original


It's likely chirp can be used to program out of band. A chirp plugin already exist although I don't know how complete it is.  Just because the display says something it doesn't mean it will actually work.  I'm sure there are filters in the radio to attenuate signals outside the bands it was meant for.  This make the question now.  
How far out of band can the radio TX/RX effectively?

freq2=[400-520MHz]
data2=00400052

freq3=[450-520MHz]
data3=00450052


I am able to program upto 498 and it receives fine, once I go over 498, it seems very deaf.

You need to program the radio with a codeplug that already has all your channels you need except for the ones above 480Mhz. You then add the  extra out of band channels you need, write this to the radio, then you have to program each channel from the keyboard, you require above 480.

Make sure when you program the radio with the TYT software you set the DIGITAL or ANALOGUE before you write to the radio as you can not change this via the keyboard.


You can program from the keypad in a limited capacity.  It's really only useful in circumstances where you are modifying a channel.  There is no way to create a new channel.  To do it you must enable the option using the software first. Then it will appear under utilities.
The chirp plug-in is available via github from travisgoodspeed. It's part of the 380usbtools package.  It's incomplete and can only do the analogue programming.  Furthermore it requires a manual read/write to the radio currently.

If you remove all of the frequency pull down picks from the list except [FrqRange] "freq0" and edit it for 400 to 498 and edit the next line as 00408098, you can program the radio with the TYT software as usual. You don't need the other ranges especially VHF unless you have a VHF radio.
Much easier than programming through keypad.

Is there a way to edit the experimental source code to allow up to 498MHz keypad entry?

Got this working and thanks! We have a lot of UHF T-Band activity here in NYC and nice to be able to monitor. I wonder if this mod would apply to all the other 480 Mhz limit DMR radios out there.

Anyone tried md2017 with this mod.
