Update
There are 2 “panels”to connect the radio. Hit the uppermost panel and it connects right away. I don’t know why they don’t show a better separation. The only problem I found was I have to force quit the app and restart it to get the “write” to show up. Otherwise the keypad won’t go down. They could also change the color of some of the text fields to make it easier to read. 8Especially when saving.
