This time the signal was too weak to see the symbols but knowing the message I could reverse the modulation to get the carrier, then measure its frequency. The spectrum peaked at -256 uHz and this offset in the decoder gave an easy decode. Without the offset - nothing, so this couldn't have been decoded without already knowing the message. -- Paul Nicholson --
