Hi Dave
Ia^2*Rloss is power lost not radiated. The Rloss figure is only they for
historical reasons...the "Efficiency" column is the only one that uses it.
You will just need more power to drive the calculated current through Rrad +
Rloss.
Thanks for the check on the down load....you both had me worried, until I
realised what I had done.
Cheers de Alan G3NYK
