My guess that they will be relaxed. From a spectrum management perspective I would not want to see too much of the spectrum taken up by modes that occupy too much bandwidth, especially if they are not spectrally efficient. As Ofcom will probably refer any request for changes of mode to me I suggest that in making the request that one is fairly general on type, e.g. data modes but specific on occupied bandwidth, e.g. 200Hz or 500Hz, that way one won't get pinned down too much and be able to experiment a bit, which is what Ofcom want to encourage. 73 John, G3WKL
