Agreed that a rig cannot detect the difference between forward and reflected power. If the reflection coeffiecient of the source is zero then final stage of a transmiter will look purely resistive to any power reflected by the load. Thereby that refelcted power is dissapated as heat. Other reflection coefficients at the source will yield lesser amounts of reflected power from the load as heat. This is true for a source equipped with a circulator and load but most ham transmitters are not equipped with a circulator and load. You must take the phase of the voltages or currents into account in order to calculate the interference power term. Only then will you be able to tell where the power goes. -- 73, Cecil http://www.qsl.net/w5dxp ----== Posted via Newsfeeds.Com - Unlimited-Uncensored-Secure Usenet News==---- http://www.newsfeeds.com The #1 Newsgroup Service in the World! 120,000+ Newsgroups ----= East and West-Coast Server Farms - Total Privacy via Encryption =---- |
