Here are the hits I gottoday:
118.125 (Seafair Air Control Primary) - heard them for the first time, trying to figure out mic. troubles.
257.8 (Boeing Tower) The A-10 was suppose to fly before the Angels, but had gear and turned back.
143.6 (BA Ground Support) Good preflight listening; get updates
170.9 (BA Tower)Also good preflight listening
238.15 (Show Center/Delta Formation)
275.35 (Diamond Formation, 1-4 Air to Air)
345.9 (Solo 5-6 Air to Air)
Anytime the BAs are around the show area (ie, Lake Washington, between Seattle and Mercer Island), monitor 238.15.
