These can be referenced in the channel configuration. Talkgroup Settingsįor DMR I created a list of talkgroups. This section lists the specific settings for DMR mode. This makes the radio decode any transmission regardless of the NAC. To make the radio decode this you can use “F7E” as NAC on the RX side. After some investigation I discovered that this was due to another NAC being used for transmissions from people not on the same repeater. That lead to the situation that an OM coming from another repeater in the net was not heard on my radio.

In the area here we have some P25 repeaters connected to each other using their secondary receivers. A bit of exerimenting showed the source: “PTT Release Tone” under “Optional Features 2”: I have just been informed that my transmissions were terminated with some strange beep tone that was transmitted from the radio. To reset to the channel default you can choose “Talkgroup Rst” from the menu. Even switching the channel back and foorth keeps the selected talkgroup. Obviously there is no reset timer or the like that reverts back to the channel default.

You can scroll through the list of configured talkgroups and select the one you wish to use for the next transmissions. If this is programmed you can choose the talkgroup for the channel from the menu/front panel. Otherwise you will have the “Group” item in the menu but cannot select a talkgroup. In addition to this the option “Talkgroup Strapped” has to be deactivated. Select the default TG from the list with the number in “List Number”. This list has to be referenced in the channel settings of each P25 channel under “Talkgroup ID”. In order to be able to switch between different talkgroups you have to have a list of TGs to choose from.

In default settings all Calls on a channel use TG1 as destination. Some of those may also have an impact on other DV modes. Pure FM is always available independantly of the DV modes. I you need to switch you have to write another codeplug. That means you can use P25+DMR or DMR+NXDN or NXDN+P25 in a codeplug but not all three. Apparently the radio can only use two of the Digital Voice modes at a time. I use the radio in NXDN, P25 and DMR modes (and FM as well). This is my memo for various options that I discovered why program&try :). It seems like Kenwood uses totally different terminology to refer to configuration items in their radio programming software.
