Dear All.

Thank you for your help on the DECCA info, so far I have not tried a Class D or E PA , my 500kHz TX having a power MOSFET in pseudso Class C, with Class D & E how is the PA output impedance calculated, for the output transformer, would it be permitted to use either a Pi or L-C_L (as I have done) to match the PA to the variometer and loading coil? .
