As long as it is conventional you will be fine, which it appears to be.
Add the frequencies to the radio, were it asks for a RAN code leave the entry as "none". This will allow the radio to pass any NXDN traffic heard on the channel. According to the MATC license they are using 6.25Khz channels so you will need to set the modulation from narrow to very-narrow.
If you want to try and figure out what RAN they are using you can set up 63 channel with all 63 RANs and scan them to figure out which ones they are using. If you are able to figure it our you could then submit it.
Have fun, let me know how it works.
