Topband: Gamma match prob, summary and new question

[Barrie Smith]

Andy:

If you get any good hints please pass them on.

After a few weeks of gathering parts, I'm in the process of building the 
pi-network specified on W8JI's site.

I was impressed with the matching range of the pi-network.  With 
experimentation, I should be able to determine how well it works, excepting 
the loss factor.

I mentioned the pi-network here a couple of weeks ago, and was cautioned 
(mostly off-list) that this method would result in losses.

Well, every matching method will have some losses.  How much is too much I 
really don't know.  It would seem to me that if I'm able to match the line 
to the load well, then the losses would be less than if I were matching the 
line to the load not so well.

C1and C2 will be a vacuum variables.  The 90 microhenry L1 will be a coil 
from a Harris 10 KW broadcast transmitter, with a heavy, edgewound 
conductor.

Should know soon.
