Confirming we are talking about programming NXDN, right? If a different system type, please start a new thread and I'll help you there.
The starting steps are:
MENU
MANAGE FAVORITES
NEW FAVORITES LIST (or select an existing one to use)
(set the options - rename etc if you want)
Select REVIEW/EDIT SYSTEM
NEW SYSTEM
Select the system type you want: NXDN TRUNK for trunking systems, NXDN OneFrequency for single frequency trunks, or Conventional for conventional channels.
For conventional only, create a new Department, then within that new channel, then program teh frequency for that channel. Set the audio type as DIGITAL ONLY and set the RAN if known. Repeat for any additional channels.
For NXDN OneFrequency, select EDIT SITE, add a new site, then select SET FREQUENCIES and enter the frequency. After that, set ID SCAN to ON or select EDIT DEPARTMENT, NEW DEPARTMENT, NEW CHANNEL, then enter the Talkgroups you want to scan.
For NXDN TRUNK:
select EDIT SITE, add a new site, then select SET FREQUENCIES and enter the frequencies for each LCN. If you don't know the LCN, just hit ENTER for now on that field. Repeat until all the site frequencies are entered. After that, set ID SCAN to ON or select EDIT DEPARTMENT, NEW DEPARTMENT, NEW CHANNEL, then enter the Talkgroups you want to scan.
If you don't know the LCN, use LCN FINDER to find them as follows: (you will need to remember the System name you set above)
In the menu, select ANALYZE then LCN FINDER. Hit ENTER and scroll to the system and select it, then select the SITE and LCN Finder will start. when it's done, it will let you know and you can set all the found LCNs.
Now one word of caution here: IF there are frequencies that are not used, it will never find the LCN for them. But, it will give you the option of saving what it has found when you exit the LCN finder using FUNC-SYSTEM. It will ask if you want to save found LCNs. Select YES.
The above should get you running.
