[Elecraft] oh no, another crazy audio idea from Holland

[Geoffrey Mackenzie-Kennedy]

Hi Paul,

How well your idea performs in practice would, I suggest, depend on the 
strength of the wanted and unwanted signals of course, but also on the *in 
passband* and skirt region IMD behaviour of the roofer(s), and all 'stages' 
that follow vs.applied AGC. Any IMD 'weakness' in this area would result in 
a compromise.
