20 years ago I hated the guy, but over time I grew to respect him. He always stuck to actual facts and presented them whether you liked it or not. I was actually disappointed to hear he had passed away in February.

The chart of his shown in Radio World clearly acknowledges the fact that up to a mile and a half is range is technically possibe when conforming to the 3 meter antenna/ground lead restrictions. Years ago he posted his correspondence with the FCC chief engineer who confirmed that the "200 foot rule" was bogus

Something that had only occurred to me recently is that in every one of his many varied calculations over the years concerning potential part 15 AM range, a- He ALWAYS based it on a Class E transmitter.. Which has a greater potential than any Rangemaster or Procaster would.

I find that interesting, because other than the now discontinued SStran AMT5000, or or maybe a home scratch built unit, but there are no manufactured Class E Part 15 transmitters in existence and haven't been since the early 1970s.

So why did he always base his calculations on Class E Transmitters? The only reason I can think of was to make the range potential of the common part 15 to appear greater than what it actually is.

This from the guy often labeled as an enemy of part 15 AM
