Default Interesting radio I found.

A few things:

a) UM-1 is the Pacific Rim designation for a D-cell. Whether one-time or rechargeable. It relates to the physical size of the battery. Not to worry about 1.2 vs. 1.5 or 1.56 V. The circuitry will handle it. Unless there is a switch inside the battery compartment (as with many Grundig & some Siemens radios), ignore the distinction.

b) P.M.P.O is a measure of what happens when you short-circuit the entire battery capacity added to whatever charge is in whichever capacitors directly into the speaker, for about one millisecond. It is an impressive, but entirely meaningless number.

c) Essentially, this is an analog radio-in-a-chip, and for all that will pick up strong SW stations, and do otherwise OK on AM & FM. But it will not stand up to any comparison with a purpose-built SW radio of the same size and band-spread. Kinda-sorta like comparing a Mini to a Yugo. About the same size, four wheels, steering wheel, doors, seats, after which the resemblance stops.

I believe these retailed originally around $20 for about a week, then rapidly were 'remaindered' for prices all over the map. I have a very small Chinese 9-band radio

https://images-na.ssl-images-amazon....L._SL1500_.jpg That I snagged at Kutztown for $1. The two D (!) cells inside were worth more than the radio. It plays OK, but the 7-band radio I snagged a day later for $10 https://www.radiomuseum.org/r/siemens_rk_747rk74.html blew it away. Today, it resides on the bench primarily to pick up LO Signals when I am troubleshooting.

Not a bad find if you are into that kind of stuff - and it should last for years. But, it is Chinese.
