[Lowfer] New bench testing of PA output filter

[Bill Ashlock]

Mike and all TX loop enthusiasts,

You may be interested in knowing that when I insert the 63uh-1.8n-63uh 
filter (IE: the Lyle filter) between my final and the loop stepdown 
transformer I loose at least 25% of the loop current for a constant 1W of 
input power. I have tried different types of cores and inductance/capacity 
ratios but the results are similar. Without the filter the total efficiency 
is about 95% and those little MPS6602/52s run as cool as cucumbers. I can't 
seem to make the Psice model agree with these results, however.

Bill
