I was at a local Salvation Army store and found this radio. QuantumFX Model: R-18US. AM/FM/SW1-SW7 RADIO WITH USB/SD BUILT-IN
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 UM11.5v. 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 bullshit 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 maximum....
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.
