Is the radio near a battery or a lot of metal. Try exposing it more.

Check all connections maybe test it on a robot from another year.

Are you running on the 2.4ghz band or 5ghz band?

Are your battery terminals all secure?

Also, I do not know if leaving your radio out of your bag after the fact is legal. I am going to let some people with more knowledge comment for sure but its worth noting.
