I thought filaments produced photons/light waves as well. You took me to light now you want to leave! Well, the light emitted by tube filaments is irrelevant to the RF function. I use light examples because light and RF are both EM waves and a lot more is known about light than about RF. Come on I just want a good basic understand on what it is the the Tx reflects the power , how it does it and a little simple math. My dad used to say if you can't explain something you think you know to someone else it might because you don't understand it yourself or lack command of the language. In this case for me it's both. What I am trying to say is that I don't know what happens inside a transmitter. Under Z0-matched conditions, as with a tuner, I believe that what happens inside a transmitter is pretty much irrelevant. The transmitter sees its designed-for impedance and that is essentially all that matters. What I am willing to discuss in detail is what happens at a Z0-match point (x) in an antenna system with reflections - something like the following: XMTR---51.5 ohm line---x---1/4WL 300 ohm line---1749 ohm load 100W -- 200W -- -- 0W -- 100W For these typical conditions, all voltages and currents are either in-phase or 180 degrees out of phase at the match point (x), which makes a power analysis the most simple analysis of all. -- 73, Cecil http://www.qsl.net/w5dxp -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 100,000 Newsgroups - 19 Different Servers! =----- |
