Graham,

Looks like about 3.5 watts DC input (3 watts RF out) is lowest I can measure.

I will send one ping starting at 19:15 utc with Op32.

Hi Graham,

I carried out the RF output measurment today for the Class D Tx & the result is......

For PA 80 watts DC input the RF output is 72 watts.

Well  that  would  be  1  watt  dc  input  for  the  day light  decodes  ? that  would   re-write  the  book  of  Ae  amps   !

 

will  set  up    rx  again

Graham,

>>>>could  it  be  reduced  by  x 100  ?

The Class D Tx PA was running at 80 watts DC input last night, I will test RF out at that level later & post the result.
