For an all-talk station, the folks at WTKK aren’t saying much. But we’re told the rumors are true: News Talk 96.9 FM is ditching its lineup of loudmouths in favor of music. The format change, which will take place right after the new year, means no more Michael Graham, who was sent packing last Friday, or midday host Doug Meehan, who actually left Boston a few weeks ago, or Rick Shaffer, cohost of the weekend “Money Show.’’ We’re told Jim Braude and Margery Eagan will be on the air as usual Wednesday morning, but that will be their last day at WTKK. Fans of “Jim and Margery’’ will be happy to learn, however, that they’re very likely to show up elsewhere on your radio dial sometime soon. No word on what sort of music 96.9 will be playing, but let’s hope it’s more soothing than Graham’s rants.
