Did you study the material on my website? My measurement method is 
clearly described in several of the publications, including the RFI 
tutorial, the AES Paper, and the Power Point for talks I've done for 
several ham clubs and conventions. The equipment consists of an HP 
Generator and HP Spectrum Analyzer (which was used as a terminated RF 
voltmeter).

My work, and its publication precedes G3TXQ's by at least five years. 
His work is clearly inspired by mine (and I would think by W1HIS's), yet 
he fails to credit either of us. All of my writing credits others who 
have made important contributions on the topic I'm writing about. I did, 
for example, reference work and texts by Henry Ott, Clayton Paul, W1HIS, 
E. C. Snelling, Neil Muncy, Bill Whitlock, Jerry Sevick, and Doug DeMaw 
in the RFI tutorial.

The "Cookbook" that is part of my RFI tutorial is based directly on the 
measured data that is discussed throughout the tutorial and summarized 
in Appendix One.
