Look up Doug DeMaw's (I think he was still W1CER at the time) review of 
the Ten-Tec 544. It was a few paragraphs of description, some photos and 
almost a full page schematic of the optional internal SCAF filter. It 
was out of the AGC loop. It also was also an unattributed copy of his 
design. He never said that in the review.
