This "GP-4L" has come up in my research. 5 ounces. 3.4" X 2.55" X .83" From $23 to $26 from what I've seen so far.

I had an itty bitty Sony Walkman radio in college and am trying to find something like that. No speaker, just ear bud.

The GP-4 radio was originally designed for the US government. The State Department is still buying them by the tens of thousands, as they want all overseas personnel and dependents to be able to receive the latest news anywhere in the world. Only a tiny radio would likely by carried at all times, and the outstanding reception on AM, FM and SW would enable them to know what was happening and head for safety in the event of another embassy terrorist "event" like the two a few years ago in Africa.

Smaller than a pack of cigarettes, the tiny Survival radio is absolutely perfect to have handy to keep informed of the latest emergency news - on AM, FM, or two short wave bands! Digital dialing lets you select - and find again - any station.

Powered by two AA batteries which last for over 150 hours (over 300 hours with the supplied ear buds), this tiny radio had incredible reception. This tiny pocket radio can keep you informed of events even if you have to listen on short wave!

...marketed by County Comm and manufactured by Degen. This is a very simple to use single conversion AM-FM-SW radio with surprisingly good performance on SW. The GP-4 is an analog radio with digital frequency readout.

This is truly a pocket radio. The GP-4 checks in at 3.5"H x 2.5" x .75" D. With 2 AA cells installed, it weighs approximately 5 ounces. Frequency coverage for FM is 80 - 108 MHz and MW is 520-1710. Shortwave is broken into two chunks. Per the manual, SW1 = 5.95 - 9.95 and SW2 = 11.65 - 17.90 MHz. My unit was more forgiving on the band edges and gave me approximately 400 kHz additional coverage beyond the specs.
