It used the famous call sign several times loud and clear (and that was from a very modest scanner on my kitchen table in Cambridge)! Must have a decent radio on board as it was much clearer than most of the "low cost" airlines earlier in the evening!
Well here in Stapleford (Cambs) my little Icom IC-R5 with its Watson W-881 Super Gainer aerial sure was picking up Essex Radar loud and clear on 120.625 on Thurs evening but I'm now kicking myself as I switched the darn thing off too early and MISSED it. Now im wondering what Air Force Ones departure schedule is like from SS so I can hopefully catch it then!
