Ulrich L. Rohde's (DJ2LR/W2) name rang a bell. Look in my folder of 
antenna transmatchs and found a copy of an article from December 1974 
(page 48) written by him. The article was called "Some Ideas on Antenna 
Couplers". Basic idea was build a "L-Network" with a 4:1 autotransformer 
between the transmitter and the tuner to drop the output of the 
transmitter to less than 12.5 ohms. I was always interested in building 
that unit to see how it would work for QRP operations. Wondering if 
anyone remembers that article or how ever build a unit similar?

>>Hi Doug,

>>When I was a younger old man, *Ulrich Rhode* (Rhode and Schwartz Instruments) and a collaborator wrote "Communications Receivers: DPS, Software Radios, and >>Design, 3rd Edition".  I would recommend this book most highly for an EE.  It gets highly technical in spots.

>>Good luck,
