The scanner uses quick keys for both conventional and trubking systems. FreeSCAN is a little buggy. It does not show quick keys assigned to systems in the left side browser window. Click on the Plus sign next to the system in trunking question and you will see a Simulcast group click on that and the simulcast page comes up on the right side. There you can set the quick key. The scanner will be set up ok not sure why trunk system quick keys do not show up in FreeSCAN system browser.
The 996XT doesn't assign quick keys to trunked systems. It assigns them to trunked sites. Therefore, FreeSCAN is NOT "a little buggy" with respect to this issue. You are "a little wrong".
