I also agree with
@jaspence make sure the SD card was formatted using EZ Scan under the top Scanner/SD Card
By default the freq/talkgroup is assigned to a default scanlist, check what your default scanlist is and change/enable if needed.
In the Trunked/Conventional tabs, make sure the proper scanlist is assigned to the frequency/talkgroup.
To check the Talkgroup's scanlist, click on trunked system name at top then talkgroup tab at the bottom.
On the General Settings screen make sure scanlist is enabled.
PM me if you need more help and I'll try to help. It can seem overwhelming when you first try to set it up, but it really is pretty easy when you get used to it. I went through the same learning curve.
