Reading the latest (July) QST, I see that I'm not alone in recommending this
technique. See "Workbench" on pages 54-55, with a photo of about 10
turns of coax wound around a toroidal core. The author hasn't quite figured
out how multiple turns moves the effective range of the choke down in
frequency though. :)
