Hi Terry, LF,

I want to add something to the TX/antenna matching discussion. Therehave often been querys about a schematic of my TX/PA system. So ifinally took the time to draw it, how it looks in principle. It is justone example how it can be done of course. Maybe it helps to get furtherideas how you can do it one your side.

First of all thanks to Andy for starting the Wellbrook discussion - it has
been very useful for me.

James - thanks for the information on the pros/cons of using Litz wire.
Although it seems obvious now, I hadn't realised the meaning of 10/44.

Mal - thanks for your helpful advice and info on your antenna loading
arrangements. I am still trying to picture it all in my mind but it seems
like the sort of relatively simple system I'm looking for - especially
keeping to 50 ohms. I have yet to find a supplier of the metal lined CH pipe
(Srewfix B&Q??)
