I did not nor do I intend to raise false hopes about fixes to existing designs which will improve efficiency.
Concerning the SSTRAN AMT3000, this apparently was designed to provide optimum performance with modulation linearity which it does almost to a laboratory standard. I fear any changes to the circuit will upset this performance and I recommend against this. Since many posters have reported good range with this unit using their recommended coil loaded antenna, I would not fear investing in this (as I have). It may not be optimum in terms of efficiency but it is effective.
My hope is that some experimenters will take up this subject and develop high efficiency AM circuits. I am not willing to do this myself, but will be willing to advise.
Sorry if I implied that there is a simple fix.
