This sort of variable signal over quite short distances has been 
reported before on signals where sky-wave is present (G to 
Scandinavia, HB, and I).

As G4GVC and G3YXM are 150+km further North than G3YMC and 
myself, perhaps the answer is that the ground wave and sky wave 
combined to enhance Toni's signal in the Midlands, but to cancel it 
in the London area.
