I was looking for 100K if possible, I think it will continue to receive more and more stations the higher it goes; FM Radio is Line-of-sight and because of the curvature of the Earth it will "see" more stations the higher it is. It is only about 79mm x 65mm x 25mm (3 1/8 inches x 2 9/16 inches x 1.0 inches,) weighs about 40grams (1.4oz) and requires 5 to 6 volts consuming 24mA. Shown here next to a Thumb Drive for comparison.
