I think the guest is right. If you can tune it at exactly 97.3Mhz FM then you don't have a problem, if you can't you may still be able to hear it in Canada but it will be noisy (digital tune only.)
I have an AIWA walkman which is universal so I switched the radio system to the north America system. It works fine.
But my brother was not lucky. One of his friend bought him a car radio from the states as a present. The radio just could not tune the 97.4 Mhz FM in BJ (it could, any way, be at either 97.3 or 94.5.) And there was no manual so he had to give it up.
For the analog tuning radios I don't see a problem although I don't think a lot people are using it nowadays.
BTW, the radio here is not expensive.
If It is too much a trouble to find it out it makes sense to give it to your family as a present before leaving China.
