Vast majority = GUM :-)

What matters is a sticker with very high PMPO number on there and lots
of blue LEDs.

Since new radios are mostly junk I haven't bought one in over 20 years
except a new living room stereo. And only because SWMBO kept complaining
that the old (well running ...) Kenwood tower was too large and "ugly".
Boy did I regret that, the new stereo is completely useless on the AM band.

I have yet to migrate into that sort of gear. Didn't have a need yet.
