"Ian White, G3SEK" wrote in message ...
How would you explain what Cecil wrote? Who else but Cecil would dare attempt that? :-) I can understand your fear... Do you think the series reactance a system offers a PA may actually improve it's incident power? For example, reducing the load impedance will usually make the output device operate in a more linear way... but the efficiency drops and the greater heat dissipation and current are likely to shorten the lifetime of the device. Is that an improvement? By improve, i mean increase the incident power. I think this is possible, and i've actually measured it, if you read my original post. If you can improve the incident power (tuning) of a PA with varying the coax length, you might be able to adjust the SWR too, in certain cases... though in my case, the SWR stayed about the same.
