Interesting that ARRL still sells reference card for the UV-5R.

It's the older UV-3R that has poor harmonic suppression, according to 
this from ARRL's website.

QST, shows the Baofeng UV-3R has poor harmonic suppression. A member has 
recently referred me to a link which shows how to correct the problem:
