Jeff seems to be a very experience man with RF. I don't doubt his
comments about what is possible with a practical situation. I, however,
am playing with some fundamentals (free space, antenna characteristics,
etc) so that I understand how to catch up to the gurus here. My toy is
the modeling program. I do like to compare theory to practical
situations, however.


Yep, while nowt is perfect, there is always worth in something as a guide. I
got spoiled by op-amps, it's a different thing imagine stuff with actual
transistors. Just one example of how tough it can be without the guides.
