This is my first time doing this. There is a local hospital that uses a DMR repeater & I would like to find the group codes used. I'm currently using a PRO-668 scanner with the discriminator output. I am getting the sound a radio makes when it is keyed up but no voice. I am getting a bunch of errors as pictured below in a screenshot. Can anyone explain what I am doing wrong here or is this what its supposed to look like.
