ROAD TEST

WHAT: "Radio on the Road: The Traveler's Companion," a guide to the frequencies and formats of more than 15,000 AM and FM radio stations in the United States and Canada, by William Hutchings ($14.95, Arrowhead Publishing; 1-800-431-7274 or 909-337-8937). Also lists stations that carry NFL and NBA games and such popular talk hosts as Rush Limbaugh, Art Bell and Dr. Laura (but not, alas, radio gods Don and Mike).

WHY: For travelers, the car radio still can be a peerless time-killer and a decent substitute for both human conversation or a map of the local landscape, cultural or not. And if you have a favorite talk show or NPR program you hope to tune in away from home, the "scan" button just misses-- or hits--way too much to be useful.

HOW: Extended, informal tryout. Carried the book in the car--it doesn't quite fit in the glove box--for six months, consulting it whenever frequent road trips faded the familiar signals of home. (Note: The type's real small. Please pull over first.)

RESULTS: Hey, it works--about 80 percent of the time. The third edition came out in 1998 (another due next spring), and station formats, especially on the deep-discount AM band, tend to change faster than the passing scenery. But the book helped make a spring weekend drive the length of Maine thoroughly happy, as I tuned from one Maine Public Radio link to the next in the chain without missing a minute of an all-day lineup that included "Car Talk," "Prairie Home Companion's" annual all-joke show and "World Cafe" (syndi- cated by the University of Pennsylvania's folk-rock-whatever WIOQ, another find). I got to hear the local news and (more important) weather in Greenville, S.C., and Harrisburg, Pa.--in both cases by announcers whose local inflections made both them and the passing countryside less alien. I found that car dealers across this great nation believe that shouting male voices with cheap reverb are the thing to have in a radio spot.

CONCLUSION: Worth more than most $14.95 auto accessories. Since it already doesn't fit in the glove box, maps would be a nice addition.

WHAT'S THE DEAL?

Two Continents for Less; Easy Belize

* For travelers younger than 26 and students who have more time than money, Council Travel is having a four-day sale on air fares to Europe and South America, starting Tuesday and ending Friday. The flights leave from BWI, Dulles and National and alight in 26 destinations, including Lima ($299), Guatemala ($239), Amsterdam ($250), Dublin ($214) and London ($169). But to qualify for these low-low fares, travelers must have an International Student ID Card (for students 12 to 32) or an International Youth Travel Card (for the 12-to-25 set, regardless of student status). To apply, visit Council Travel on 3301 M St. NW with proof of your age or student status, a passport-size photo and $20. To obtain the card before the sale is over, you must apply in person rather than by mail. (Travel is Nov. 1-Dec. 16 and Jan. 3-March 31, with some blackout dates.) So, do the math: a little inconvenience for a $169 round-trip flight to London equals . . . a smart deal. 1-800-226-8624 or 202-337-6464, www.counciltravel.com.

* To do Belize on a budget, Capricorn Leisure Corp. trades cushy comforts for low cost. The $508 package to Caulker Cay includes: American round-trip flight from BWI, National or Dulles, 20-minute air transfer to the castaway island and five nights of accommodations. What's missing: pool, air conditioning, room service. What's hard to beat, besides the price (Belize flights alone start at $677): the quaint charm of the turquoise-and-pink, seven-room, beachfront Trades Hotel, easy diving access to the barrier reef and no high-rise, wide-body resorts. Three-day advance purchase is advised, and travel must be completed by Dec. 10 (add $50 for weekend departures). 1-800-426-6544, www.capricorn.net.--Andrea Sachs

TRAVEL TIP 117

Tape That!

PROBLEM: Teens on overnight trips sneak out of their hotel rooms after their chaperons turn in for the night.

SOLUTION: Trust but verify: Tape their doors from the outside with masking tape.

TIP REPORT: Tipster Maggie Holobaugh of Takoma Park learned about this one the hard way, as a middle school student on a class trip. "Every night, teachers would tape our hotel room doors from the outside. If we left the room, there was no way we could 'tape ourselves in' again!"
