Has anybody built or played with high IMD solid state amplifiers? There is a
system called " Feedforward" which is well explained in "Single Sideband
Systems & Circuits" But i would like to know if anybody has implemented a
working model. Third order imd figures of greater than 60dbc is achieved. It
certainly would make a great driver.
Alternatively could your achieve high level of imd performance of greater
than 60db by using say a 4cx600J, with low plate voltage and low drive power
to achieve good third order imd performance? Maybe there is a high
performance imd tube that i am not aware of. Certainly the vast majority of
ham transceivers the imd performance is certainly very poor. Anybody looked
at the FT847? its a SHOCKER, maybe i just have bad example.
