Default Interesting radio I found.

I was at a local Salvation Army store and found this radio.

The USB flash drive and SD card ports play MP3 music.

Everything works except the telescoping antenna is broken off (that's
easy to fix, as soon as I find one).

But I'm a little confused. In the battery compartment it says to use UM1
1.5v. The PDF file (above) says rechargable batteries. And there is a
plug for a wall wart listed at 6V on the radio.

In the PDF file it also says D cells.

I dont do much with rechargable batteries. Are these UM1 the D cell
equivalant rechargables?
Just curious, I only intend to run it from the built in AC cord.

This radio was made in 2012 (sticker inside battery compartment).

This is the first portable radio I have ever seen that has a USB and SD
card for MP3 music, and with 7 shortwave bands plus AM and FM it does a
lot. Well worth the $5 I paid.

One other thing, there is a sticker on it that says it has 1000 watts
P.M.P.O HQ sound system.

YEA RIGHT..... 1000W from a 5" mono speaker powered by 4 D cells. Talk
about bull**** advertising....

Has anyone ever heard of a P.M.P.O power rating?

Either way, for mono, it has decent sound, which may output 5 watts

I bet this was a fairly costly radio when it was new....

Back to looking for a schematic for it. I dont really need one, I just
like to have them for everything I own. So far no luck finding one.

PMPO, which stands for Peak Music Power Output or Peak momentary
performance output, is a much more dubious figure of merit, of interest
more to advertising copy-writers than to consumers.

It was thought up for those who are impressed by big numbers when buying
audio gear. (Been around for years, google not working for you ??)
