From G3PLX:
I don't think the presence of the spurious emission (near 60kHz) from the
LORAN transmitter would cause any trouble to MSF itself. A quick calculation
says that the nearest spurii from the Rugby LORAN transmitter to the MSF
transmission would be respectively 8.9139804 Hz low and 5.94265 Hz high of
60kHz, and probably a long long way down on the main 60kHz carrier.
Of course that doesn't say that there isn't some disturbance from the LORAN
transmitter to the MSF transmitter due to non-linear effects arising because
of the proximity of the two transmitters to each other. The NPL people might
be more worried about that than the far-off sidebands which bother us up
here. But if there were effects like this, the solution wouldn't help us at
all.
