Yup. My 5RV2+ has birdies at 416, 442, and 468 MHz (no antenna). Nothing on the other frequencies listed in the original message.

Baofeng radios have a 26 MHz reference oscillator.
The harmonics of 26 MHz in the receive range of most models would be:
104.0
130.0
156.0
416.0
442.0
468.0
494.0
520.0

There may be other "birdie" frequencies from other internal or external 
sources mixing.

What you receive can depend on how good or poor the shielding is on a 
model or particular radio and what type of antenna you use or if you 
remove the antenna.
