Has anyone else heard from the seller?

I just got another email...

We've sold this product for a long period of time, and we haven't ever met such kind of problem before. We're still finding out the solution.

We usually listen to PM radio in Taiwan, and it wouldn't interfere.

Could you please kindly let us know the range of AM radio you listen to? Like FM in Taiwan is around 80 to 149.
So we'll test it more precisely to solve this problem for you.

Sorry to make you feel inconvenient very much, and please say sorry to your friends for us ,too.
... sorry friends!
