Transmitter Power Supplies

Publish date:

I commend you on your recent article “How Transmitter Power Supplies Evolved” in the Feb. 1 issue.

I enjoy reading articles of a historical nature, especially those that contain pictures from the period. It’s obvious James O’Neal spent many hours of careful research and is well versed on the subject.

In an age when trade journals tend to focus exclusively on new products and trends, it adds perspective to see where the technology evolved from and how early industry pioneers attacked the challenges of their day. I was so impressed with this article that I forwarded it to my 83-year-old father, a ham and director of the local civil defense communications relay team. I’m sure he will enjoy it also.
