This is fairly typical. I’ve seen some as high as 8 minutes. 

Some tips related to PA temperature:

- Make sure all right-side hardware is tightened

- Running from a lower supply voltage (e.g., the 11 V internal battery)
  should reduce power dissipation

- Keep the radio out of direct sunlight when possible

- In contests, use hunt-and-pounce operation, not continuous CQing
  (this tip applies to QRP operation in general; listen more
  than you transmit)
