[David Ferrington, M0XDF]

OK, I accept what you are all saying about the gain, I was just  
postulating :)
I agree it does drop off, but I didn't think that much.
Anyone tried it with CONFIG:AF GAIN set LO? I haven't, just wondered.
If there was a config control for an offset, it would need to be based  
on the 4 'strenghts' I think, not on the Fx number, but the digit
