Now that I think about it, the 10 amp fuse should work fine, even for
CW, unless the Scout is using a very inefficient transmitter circuit,
which I doubt is the case.
I never really knew the difference between a fast blow and slow blow
fuse of the same value. So, if the fast blow does its job too quickly,
stick a 10 amp slow blow in there and see what happens.
