Is this your first vertex radio? If so you need to activate the channels in the bank (if they're Greyed out) by scrolling down the channels list and hitting the space bar.
Also go to channel/group allocation and put 16 channels next the group name.
Tip: I see you're programming some PD channels for recieve only, go to the area of the transmit frequency and hit the space bar and you should get ---.----- that means the channel is recieve only and will give you an error when you try to xmit.
