This is really very impressive Joe.  I'm listening on 18.143 at the moment
and adding the notch and equalising as you suggest above actually turn
barely readable audio into quite comfortable copy.  Someone your side of the
pond is talking about the K3, not sure of the callsign though!

73 and Happy Christmas!
