OK thanks gentlemen, it works! This changes everything now. Holy smokes. OK, just in case someone else makes the same mistake as me, I had my control channel modulation set for TDMA CC instead of P25 LSM. So the unit was powering up wrong. I thought that was the setting for all of them, and I would simply click on the P25-LSB button on the bottom to get it receiving. But of course you can't do that when it is standalone.
