Hey, everybody. I am new to working with NXDN. I recently purchased a used Kenwood NX-300-K4 station. I want to use it with my mmdvm pi-star hotspots. Both are Chinese made but seem to support NXDN mode. I tried to create my codeplug from scratch. I created a NXDN channel with the hotspot frequency. I also set my official NXDN ID everywhere. When trying to transmit, the hotspot does not react. Perhaps I have not programmed the station correctly. Maybe someone can tell me the correct steps for programming this radio. For programming I use the application KPG-111Dv.5. Thanks in advance.

To anyone looking to acquire commercial radio programming software:
Please do not make requests for copies of radio programming software which is sold (or was sold) by the manufacturer for any monetary value. All requests will be deleted and a forum infraction issued. Making a request such as this is attempting to engage in software piracy and this forum cannot be involved or associated with this activity. The same goes for any private transaction via Private Message. Even if you attempt to engage in this activity in PM's we will still enforce the forum rules. Your PM's are not private and the administration has the right to read them if there's a hint to criminal activity.
If you are having trouble legally obtaining software please state so. We do not want any hurt feelings when your vague post is mistaken for a free request. It is YOUR responsibility to properly word your request.
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).
This is a large and very visible forum. We cannot jeopardize the ability to provide the RadioReference services by allowing this activity to occur. Please respect this.

Check your BER and tune the hotspot accordingly. You also need to enable NXDN on the hotspot. Also, it may take a second for the transmission to be captured by the hotspot, quick blips are not ideal.

Looks like the selected group in the screenshot is "10" which should be the "parrot" group, which should work.
I have no idea why it isn't even partially working. No special tuning of the hot spot is needed for receive, so it should be at least receiving- even if for some reason your radio won't receive the response due to a tuning issue.

Yeah! When I push PTT button , I get voice message: "no linked" But as I understand, parrot should work.
Do I need to prescribe TG in the station or in the NXDN settings in Pi-star?
In the station so it transmits the respective TG. In Pi-Star it is needed as well so the reflector of your choice is enabled by default. Otherwise switching them could take some time.
I never owned a NXDN radio myself, I just know the foundations of how it works

In the pi-star, the NXDN groups are set by PTT to connect. You will need the groups set in the radio to transmit to the right groups. You may have "10" as the default, but unless the radio is transmitting to group 10, it will think that the pi-star is changing groups. The radio defaults to no group, or '0', so transmitting it will give you the "not linked" as zero is not a valid reflector group.
Set up groups in the radio and assign the group list to the channel. Then go into the radio's contact list to find the group you want (try 10 for example) and PTT to the pi-star and you'll likely find that it will work.

All right, boys! Thanks everyone for the very helpful hints. I've figured out a lot of things thanks to you guys. But there are still a couple of questions I don't understand. There is this resource: NXDN Dashboard
Their NXDN Reflector 711. I see it in the general list of Pi-Star . And I've already connected to it. But I see that they have a list of rooms. By default, I'm connected to the English room. (Dest 11). I wonder how to connect to the other rooms. (Like the ECHO room, Dest 99.)
P.S. And I see my hotspots do not support NXDN mode. Well there is a local repeater with support for this mode. I ordered mmdvm modem with NXDN support from the Chinese).
