 However, Mediabase reports The Pulse's playlist under X026-FM rather than S012-FM.The Pulse's airchecks were changed to the same voiceover as the old Flight 26 branding rather than carry the old jingles from the old Sirius 9 channel.Most recently, to encounter sister channel The Blend's overhaul in September 2009, The Pulse dropped most of the 1990s songs that can already be heard on sister channel '90s on 9.
