I've discovered that many of the speaker/earbud models use the earbud wiring as an antenna. Without the earbud plugged in, no reception. With the plug in, no speaker. Strange engineering.

An Amazon search will bring up a bunch of FM/weather radio combos. This one has a telescoping antenna and ok reviews. No evidence of earbud capability tho. Priced right. 8 oz sans batteries.

Midland makes an excellent weather-only portable. I've had it for several years.
