I would like to remind us that it is our responsibility as hams to ensure that our radios are compliant with the spurious emissions rules applicable to where we operate. In many cases, the manufacturer does that for us. But for radios that are imported illegally as most of the inexpensive transceivers sold on ebay and Amazon are, it is our responsibility to quantitatively assess the radio's compliance with the rules ourselves before transmitting with them.
I would be interested if anyone who does this mod who has the ability
to check for spurious signals when unlocking the 220 feature to let us
know what they find.

As for illegal imports, the FCC has started enforcement actions
against a few companies. Baofeng, I believe, made some changes in
their radios recently to comply.

Just about 3 years, ago, I purchased a pair of BF-888's which were
advertised on the front of the package as license-free radios, like
they were FRS radios, but they weren't type accepted for that. They
didn't say they were FRS radios. Apparently the box advertising was
for another country, perhaps?

They were modifiable with CHIRP or other software to work in the 440
ham band, and can be put on FRS or GMRS frequencies, so they're useful
to me, but strictly speaking, I shouldn't use them on FRS or GMRS
because they're not type accepted for those services and they run
higher power than allowed for FRS (and I haven't). I can use them for
the 440 ham band.

These radios can be put on commercial frequencies but again, that
would be illegal in the US.
