Hi Peter, yes I think I have seen that before when we were experimenting. As
you say this looks totally different. I do have some Spectran and Argo
screen grabs. The strange thing was the approximately 1.5Hz spacing, which
doesnt seem to relate at all to Loran. Its been off for sometime now. It
sounded Loranish but any pulse system probably would sound similar, and the
strength on the 3 sec Argo screen looked about right for Rugby.
Strange......
