Start here: An RF burn means current or electric field is concentrated at a contact point. Stop transmitting immediately; it is a safety failure, not a normal inconvenience.
Why this changes a real station
High RF voltage, common-mode current, poor bonding, exposed conductors, or the operator bridging two RF potentials can cause painful deep heating without the reflex of a low-frequency shock.
What it looks like in practice
A metal knob, microphone, connector, or counterpoise end can look harmless while carrying substantial RF potential on one band.
What to do next
Reduce power to zero, prevent access, inspect the complete antenna and station current paths, correct the cause, and perform the required RF-exposure evaluation before resuming.
Evidence boundary
Keep frequency, reference plane, antenna geometry, losses, measurement method, and safety conditions attached to the conclusion. A match, a DC check, or one field symptom does not prove efficiency or identify the complete RF path.
