Washington is expected to get its second Spanish language station next week when ILC Corp. completes its purchase of music station WLMD-AM (900).

The new station, which will carry the call letters WILC after its owner, Israel Lopez, is expected to go on the air as early as Tuesday. The Laurel-based WLMD is owned by Mid Maryland Communications and went on the air in 1965. Pat O'Leary, program director of WLMD, said the 15-member staff had been notified of the change a couple of months ago but had decided to stay until the takeover. "Since 1980 we have been a hybrid of pop, rock and oldies, and we work on a creative presentation," said O'Leary. "The staff is close-knit and we believe in radio for the sake of entertainment."

The area's other Latin news and music station is WMDO-AM (1540). Myers Memorial

There will be a memorial Sunday for E. Carlton (Bud) Myers, who died last week and who led the old WOOK and current WDJY-FM (100.3) for many years. It's scheduled for 3 p.m. at St. Mark's Episcopal Church, 12621 Old Columbia Pike, Silver Spring. Geronimo in the Morning

The morning team for the last eight months at WAVA-FM (105.1), known as Charlie and Harrigan, were released by the Top 40 station this week. Alan Goodman, regional vice president of Doubleday Broadcasting and general manager of the station, said he couldn't discuss the reasons for their departure because of legal negotiations. Don Geronimo is now doing the morning show. Change at ABC

Ben Hoberman, president of ABC Radio, announced his resignation this week, effective next month when the merger of ABC and Capital Cities Communications Inc. takes place. Hoberman has worked for ABC for 36 years, six as president of the radio division, and has been credited with the tremendous growth of the country's largest radio operation. No successor has been named. King Expansion

Larry King, the reigning voice of talk, will be starting his nightly show an hour earlier -- at 11 p.m. -- starting Feb. 3. Mutual Radio Network announced this week that King will now have a six-hour program, with the last two hours a replay of the opening interview and phone calls to the guest. WAMU's Alterations

After weeks of speculation, WAMU-FM (88.5) has decided to move "Weekend Edition" to its Saturday schedule starting at 8 a.m. tomorrow. That will give WAMU a three-hour edge on competitor WETA-FM (90.9), which added the National Public Radio newsmagazine last week at 11 a.m.

"The NPR programs appeal to our listeners, and this is one more thing they will enjoy," said WAMU program director Craig Oliver. "We wanted to put it on, but not at the expense of bluegrass. The evidence is that bluegrass will do very well between 11 a.m. and 3 p.m., one of the strongest listening times in radio." Youth Ambassador

Anitra Rowe, producer of "New Attitude," a youth news program on 15 public radio stations, including WPFW-FM (89.3) every other Saturday, was selected by the National Center, a volunteer network, and Coleco, the makers of Cabbage Patch Kids, to be an international youth ambassador. Anitra, 11, a resident of Fort Washington, has been a volunteer with Pyramid Communications, a youth radio network, for 1 1/2 years. Tributes
