    To obtain Motorola software see the Sticky in the Motorola forum.

    The various other vendors often permit their dealers to sell the software online (i.e., Kenwood). Please use Google or some other search engine to find a dealer that sells the software. Typically each series or individual radio requires its own software package. Often the Kenwood software is less than $100 so don't be a cheapskate; just purchase it.

    For M/A Com/Harris/GE, etc: there are two software packages that program all current and past radios. One package is for conventional programming and the other for trunked programming. The trunked package is in upwards of $2,500. The conventional package is more reasonable though is still several hundred dollars. The benefit is you do not need multiple versions for each radio (unlike Motorola).

Tytera How to program TYT UV-380 for simple radio to radio use

Hi,

I have been using TYT MD680D in a radio to radio (no repeater) short range function.
Due to supply issues I've moved to the UV-380 and am having issues caused I think by not setting the channel information correctly.

What I want to do is for handset a to speak to handset b and handset c. All on one channel.

Do I need to set caller groups etc? Can I set them so that they just broadcast and receive on the designated channel (we have an ofcom license)

I have so far just set the channels but not set anything else (ID, Contacts, groups etc)

Im sure this is the most basic of basic questions but all I find on the web is info about rpeaters and long rance aplications.
Basically I just want two way coms between 2 or 3 local handsets

I don't have the UV 380 but I do have a few other radios including the older, single band MD 380. If you are trying to use DMR and not analog to communicate with other users then yes, you'll need to make sure that your other DMR settings match as well. Here is an example of a DMR simplex channel that I have programmed in one of my radios;

The short answer:


Channel type is digital
Frequency 441.000 (send and receive / no offset)
Digital ID (my DMR ID)
Time Slot 1 (1 or 2 is your choice but they should all be the same)
Color Code 1 (again, your choice but they should all match)
TX contact (I have one for simplex labeled Comm, you'll need to create your own)


If you choose an analog channel, then you won't need the setting above other that frequency but you may want to choose some TX and RX PL tones to keep the chatter down.

You mentioned an "ofcom license" I'm not familiar with that but I'd suggest that you be licensed to use whichever frequency and mode you elect to use.

thank you.

the bit that i think is confusing me is the contact.

i can make a contact in the CPS which is eithe a call group or a private call.
having read up, a private call is a single radio.

however, i can’t add private calls to RX groups and i can’t see how to add radio is to call groups.

can you share the steps to make a simplex TX contact as you mention

Unless I'm misunderstanding your needs, you're not making a private call. I'm assuming you want everyone in your group to receive each of the transmissions from all of the users just as you would if you were running in analog, is that correct? If that's the case, you'll be using a group call. The talk group can be any eligible ID number. You could even reuse a current one since you won't be transmitting over a repeater. I suggest a unique one for clarity's sake.

Here is a screen shot of the code plug settings on my MD380. You'll first need to create the digital contact (in my case I reused an old one that I no longer used) and then followed up by creating a new channel (as shown on the left) As I noted above, you have latitude in which time slot and color code to use but they must be consistent between users. What is important is that each user have a unique user ID programmed into their respective radio.

Hopefully this is close enough to the UV 380 to get you going with your codeplug

Getting the 680s to work with others does take some experimentation. They're very good radios on the reliability, simplicity and quality front - but to get them to communicate with 'ordinary' ham style DMR radios needs the ham radio to be stripped back to basic functions. Forget the groups and other clever features. go with the all call group, cc1, slot 1 and simplex - this forces the radio to use the simplest possible mode and should work. The 680 works well with systems that are basically conversions from analogue - so a company who had 4 FM channels, just ends up with 4 digital ones. They could of course run on one frequency with different programming but that's where they start to lose compatibility.

Haven't heard from the OP in over a month, I wonder if he got things working?
