WXTR-FM/AM (104.1/1560), the reliable oldies station, has moved its offices 25 miles closer to Washington from La Plata. It is now headquartered right off the Beltway in Marlow Heights, in new quarters that cost $250,000. The transmitter remains in La Plata. "We sound better because we have rerecorded all the music, which took us 3 1/2 months to gather and record. And it makes the station and its personnel a lot more accessible to the total area," said Bob Duckman, the station's morning guy and program director. New Voices

Joe Palka of WRVA in Richmond is joining WMAL-AM (630) as production manager and weekend personality on May 1. He will be doing on-air shifts 2 to 6 p.m. Saturday and 1 to 7 p.m. Sunday . . . The new overnight announcer at WRQX-FM (107.3) has taken "Chris Jagger" as his on-air moniker, but at his last stop, WBMW-FM (106.7), he was known as Tommy Lee. At B-106, D.C. Stevens is taking over the all-night shift and Shotgun Phil has joined as a part-time announcer. Honor Roll

A new organization, the Washington Music Disc Jockey Hall of Fame, inducted 18 charter members last night, but not without some skeptical reaction from the radio community.

The people behind the effort wanted to remain anonymous, according to Michael Zuckerman, who works with Nard's Rock and Roll Review, a deejay service. "Some people in the broadcasting business -- radio, advertising, records -- got together and were talking about things they heard on the radio," he said. "It was about the same time as the Academy Awards, the Hall of Fame stuff with Mickey Mantle and Willie Mays. And we found out there wasn't anything similar for radio."

The group, according to Marcia Call-Pongrace of the local March of Dimes office, included one March representative, Michael O'Harro, the owner of Champions and a former disc jockey. "Basically," Call-Pongrace said, "because we work with so many radio personalities, we wanted to recognize their contributions. And we wanted to do this in conjunction with National Disc Jockey Day," which is today.

The criteria, she explained, were service to the March of Dimes and longevity in the market. Some station officials, who did not want to be quoted, thought the Hall of Fame event was too much a public relations event and criticized the selections for including some announcers who hadn't spent much time in the market.

The ceremonies took place last night at Champions, and 25 percent of the bar receipts went to the local March of Dimes chapter. Pictures of the Famers will be displayed at the Georgetown bar. Chosen were: Tom Walker of WASH-FM (97.1), Don Geronimo of WAVA-FM (105.1), Marty Dempsey of WBMW, John Dowling of WCLY-FM (95.5), Scharmaine Foster of WDJY-FM (100.3), Donnie Simpson of WKYS-FM (93.9), Beverly Fox of WLTT-FM (94.7), Bill Trumbull and Chris Core of WMAL, Jim London and Mary Ball of WMZQ-FM (98.7), Greg Cole of WPKX-FM (105.9), Jim Elliott and Scott Woodside of WRQX, Doug "Greaseman" Tracht of WWDC-FM (101.1) and Bob Duckman of WXTR. The list also includes Andy Parks, WMAL's traffic reporter, and George Michael of WRC-Channel 4, who started in radio and does morning reports for Q-107. Public Monies

WETA-FM (90.9), which receives 60 percent of its operating budget from its members, had raised $167,175 by Thursday noon in its spring membership appeal. The drive ends tomorrow night.

WAMU-FM (88.5), which relies on listeners for 65 percent of its budget, ends its pledge period tomorrow at noon. By noon Thursday it had $124,000 from the on-air appeal, which it added to $45,000 from an earlier effort to get members to renew.

By yesterday morning WPFW-FM (89.3) had a tally of $65,000. Its membership drive ends Sunday night, but then it switches to an "Adopt a Watt" campaign to raise $50,000 for a new antenna and other equipment. One watt costs $5.

Over at National Public Radio headquarters, where the national campaign was handling interviews with celebrities in Washington, New York and Los Angeles and keeping a tally on how well the member stations were doing, the atmosphere was frantic but upbeat. As singer Carol Lawrence was saying, "I use radio as a marvelous information partner during the day," someone was calling KTOO-FM in Juneau to check its progress.

As they registered a $2 million tally on the board midway through the third day, Pam Sweat, the Campaign '85 coordinator, said there had been very few snafus. "Arthur Miller didn't show up at the St. Regis, and we were upset," she said. "But then he called and said he was delayed at the dentist and didn't think we wanted him with his mouth full of cotton." Today Gerald and Betty Ford are scheduled to be interviewed, and Pearl Bailey will be anchoring from Washington.
