[600MRG] FT Question Answered?

[Bill Cromwell]

Hi Frank,

That is what I was going to say in reply to your latest query. If you 
are using audio modulation in upper or lower sideband SSB non linear 
amps will ruinate and splaterate it.

But once in the RF domain we can use non-linear devices, such as heterodyne converters, Class E amps, etc.  Did I get that correct?  73 Frank K3DZ  / WH2XHA
